Pipe connection: copper fittings

There are two main types of fittings for copper tubing: Capillary solder fittings and press fittings.

plumbing copper fittings

Connecting copper brazing process is based on the capillary attraction of copper pipes, fittings and soft or hard solder for soldering. Copper pipes and fittings for soldering is collected and heated to the desired temperature, the solder is applied to the neck of the fitting for copper pipe and melt. Due to the capillary attraction of the solder is drawn into the gap between the pipe and fitting to form a reliable connection.

Press fittings crimped press systems tools. For different sizes of fittings are appropriate crimping jaws. Thanks to consistently obtain a constant force crimp durable reliable permanent connection pipe and fitting. Technique instant cold press connection speeds up the process of installing copper plumbing pipe 3 times and makes it safer because it requires no heating.

Boilermate problems

Hydraulic Externally very similar to the expansion tank flange heating systems. However, the appointment and service conditions have other, hence there are structural differences.
First, the mode of operation over the accumulator loaded. In normal operation, its frequency response ranging from 5 to 15 times per hour in a properly-chosen volume of the accumulator. If the volume is chosen correctly, this quantity can increase up to 20-30 times per hour. Of course such an operation requires a robust, resilient membrane that can withstand a large number of loads. Amtrol WH-41Z Boilermate, Amtrol WH-41L, Amtrol CH-41Z Boilermate Champion Indirect-Fired Water Heater, Amtrol CH-41BZ, Amtrol CH-80Z Boilermate Champion.

Secondly, hydraulic accumulators are used in household plumbing, so the material must be non-toxic and approved for use with clean drinking water.
Third, the water supply system in most cases comes from a well or wells. It is saturated with oxygen, which is released and accumulates in the membrane. Therefore, the large accumulator at the top of the diaphragm and the valve sleeve is to vent the air. The appearance of the accumulator presented earlier in Figure 5.

Fourth, the accumulators are usually placed on cold water line in the water system, so in terms of the temperature at which they are being more benign regime. Typically, the water temperature in the system can not exceed 30 ° C.

As Boilermate and indirect water heater systems, hydraulic accumulators are filled with water is not full. The volume of "issued" when using water accumulator is less than the useful volume of the expansion tank heating system.

Other features of the expansion tanks

Expansion tanks may be used to prevent damage to the system from water hammer. This phenomenon occurs in the pipeline at the sudden turn off or turn on the pump, quick opening or closing the valve. Loads can be many times greater than static and it can lead to the destruction of pipelines, threaded connections or plumbing devices. To avoid this, and given that the volumetric changes in the pressure variations are small, are encouraged to use expansion tanks of small capacity 0.2 liter

Also, tanks can be used as a tank with a fire liquid fire suppression systems, and as back-up tanks in those cases where the electricity is turned off. Hydraulic tanks are used not only in domestic but also in industrial and agricultural water supplies. At the same household series is designed for working pressures up to 6 bar and the Professional Series - up to 16 bar.


The design of the expansion tank is shown in Well-X-Trol Well Tank

Before proceeding further to the detailed description and principles of selection of tanks, you need to say a few words about the main elements of these devices the membrane.

Choosing energy-efficient pumps for water wells and other needs

In the water supply borehole Circulating Taco 007 pumps play a major role in Tacoity consumption. Currently, their market is represented by numerous companies pumping near and far abroad. The bulk of the downhole Circulating Taco 007 should be allocated Grundfos, Taco, Espa, Little Giant, Pedrollo, Speroni, Dab et al.

Deviations of the parameters of Grundfos UP15-10SU7P/TLC pumps in operation

Members of pumping equipment have a choice, and often, considering proposals analogues, preferred option with a lower initial price, paying no attention to the cost of subsequent maintenance. At the same time selecting the best option must be done from a position of minimizing the total amount of expenses for the period of the equipment. In this method of analysis will help the consumer life cycle cost of equipment, in which the main role belongs to the cost of the pump life. The amount of energy and materials used by the system depends on the type of pump, the type of installation and operation method of the system. These factors are interrelated.

Moreover, they must be carefully matched to each other, providing for its work, the lowest energy consumption, the lowest operating costs, other benefits. The initial purchase price is a small part of the cost of "life cycle" for commonly used pumps. Analysis of the life cycle cost is a management tool and can help companies minimize the amount of costs, maximize energy efficiency of pumping systems and determine the most effective solution. Components of the life cycle cost analysis typically include: initial cost, installation costs, fees, energy costs, maintenance costs, repair costs, downtime costs, environmental costs, the cost of recycling.

Grundfos UP15-10SU7P/TLC with Comfort Valve

National and global markets become more competitive, organizations must continually look for ways to cut costs to improve profitability of their activities. Work equipment company deserves special attention as a source of cost reduction, especially as a source to minimize energy consumption and reduce the downtime of the enterprise. As an example, consider two alternative pumping equipment for installation in the borehole. The first option - the pump Little Giant 10-120-100, second option - the Grundfos pump 26-99.

Grundfos mq3-35 – a power pump for a great plumbing syst

Based on the high degree of reliability, due to reliable protection against surges and voltage fluctuations, overheating, overloading, "dry run", etc., the service life of Grundfos pumps more than two times higher than that of pumps Little Giant. To begin to compare the cost of the designed equipment: Little Giant 10-120-100 - 1493 Euro, and the SP 125-5-A - 7940 Euro.

PEX tubing pipe and household use

PEX polymer is a material obtained by cross linking the carbon atoms using three different methods. These methods result in PEX-a, PEX-b, PEX-c. Even though the same material is obtained by using these manufacturing processes, the difference is in PEX costs. It costs a lot less to fabricate PEX-a and PEX-b than it costs to make PEX-c.

Many times when using PEX tubing people can see that the resistance of this material is not quite as good as it should be. Used in bathrooms PEX has a major disadvantage.

When the cold pipe is placed next to the hot pipe, water will start forming on the cold pipe, and it will eventual fall on the floor. When living in a building, this means that the neighbors living downstairs will get a permanent wed wall from the pipes used above. The problem is usually solved with isolation on top of the polymer pipe. This means additional costs and additional work. If the bathroom has in wall pipes, the walls will have to be removed so that the plumber can reach the pipes.

Even so, PEX supply stores still have a lot of good things to say about the material they are selling. PEX supply companies have an increased demand for this product only because it is much cheaper than traditional metal pipes, and it is a lot easier to install and use, requiring far less fitting tools.

But costs can reach the same amount, when thinking of permanent replacements of the tubes. If the pipes work perfectly for the cold water installations, in hot water these pipes can cause a lot of problems.

What polymer pipes are really good for is electrical cabling. Some cables need to be placed on the exterior walls inside the hose, thus representing a danger to children or even to adults. Polymer tubes can hold the cables together in an isolating layer.

Domestic Taco pumps. How to choose right?

Pumps of all types presented on the market today differ in the first place, technical characteristics. In addition, the pumps vary in purpose, principle of operation and size.

Main technical characteristics to which attention should be paid, by choosing an Taco pump - his head and power.

• Taco 007 SF5 - Taco 007 Stainless Steel Circulator Pump
• Taco 007 F4 - Taco 007 Cast Iron Circulator Pump
• Taco 007 F3 - Taco 007 Cast Iron Circulator Pump
• Taco 007 F5-7IFC - Taco 007 Cast Iron Circulator Pump with IFC (Integral Flow Check)

Pump head determines the maximum depth at which it can pump water. Performance of the pump, its ability to pump a certain amount of fluid per unit of time depends on its power.

The pressure is calculated as follows: first calculate the distance from the source water to the level of water-points. For example, if the well is in the area is filled with water to a depth of 20m, a crane located on the second floor of the house, at a height of 4 m, the required distance will be 24. Then make corrections on the coefficient of head loss of the jet, due to friction, the value found in this case is multiplied by 1.15. Then add the length of the pipeline, from home to the wells, for example, 7 meters. Thus, a value indicating the minimum allowable pressure pump. In the calculation of this value is 34, 6 pm

Based on the average liquid flow rate is determined by the required pumping capacity. Suppose, for the needs of one person to 800-1000 liters of water per day. The resulting number is multiplied by the number of inhabitants of a country house. For example, a family with two children will spend a day about 3600 liters. We add to this flow of water for irrigation area of 500 liters per day per hundred square meters, with an area of garden in five hundred parts consumption is approximately 2500l.

Eventually creating a sum / 3600 2500 = 6100 liters or 6.1 cubic meters. m / s gives a rough idea of the required quantity of water consumed on the farm and, therefore, helps to orient the choice of the pump power required.

Regardless of all its features, any Taco pump provides comfortable accommodation in a suburban environment at relatively low cost.

Plate heat exchanger

Heating surroundings enters the apparatus through the pipe flow of coolant in the unit, located on the fixed base plate (see picture) and through the angular hole gets in the longitudinal collector formed edges of the plates with angled holes after assembly.

Heating surroundings in the collector comes to the last plate is distributed over the channels between the plates, which are reported in one corner of the collector through appropriate arrangement of the seals. When driving on sub plate channel heated medium flows over the undulating surface of the plates, heated from the reverse side of the heating surroundings. Heated medium then enters the pex manifold and exits the apparatus through the pipe out of coolant.

Heating surroundings is moving in the apparatus toward the heated and fed through pipe water flow coolant then passes through the lower reservoir, is distributed through the channels and moves on them. Through the upper reservoir and the nozzle exit of heating water leaves the heat exchanger.

Multi-pass plate heat exchanger

Usually used one-way plate heat exchangers. Their distinguishing feature is a 100% backflow of the two media. All input and output connections are connected to the fixed plate. This method greatly simplifies the installation service. A small temperature difference between the environments may require the use of multi-pass plate heat exchangers. In this case, the connecting pipes are fed to both a fixed and a clamping plate.

Mixing valves

diaphragm valve - butterfly valve in the form of an elastic membrane, moved along the axis of the flow in the saddle valve (Fig. 5). Diaphragm valves are particularly well suited to work in hostile environments, because they do not have the seal and movable metal parts are separated from the working environment diaphragm.

diaphragm valve

hose valve - ceiling flow rate through the pinches elastic (rubber) hose, inside of which is transportable operating environment (Fig. 6). The main advantages of hose valves: design simplicity, efficiency in the sludges and pulps (where most other types of valves is broken), resistance to corrosion and abrasion.

hose valve

Depending on the working environment and its parameters are divided into steam valve (for water and steam), energy, petroleum, sewage, ventilation, cryogenics, vacuum, tank.

By Material distinguish body parts of PEX fittings:

1) steel (carbon or stainless steel);
2) stainless steel;
3) titanium;
4) iron (cast iron);
5) Ductile iron;
6) non-ferrous metals;
7) PEXs;
8) ceramic (porcelain);
9) glass.

By their functional PEX fittings divided into the following classes:

valves designed for complete coverage of the flow in the pipeline;

Control Valves - to regulate the flow of the working environment in order to regulate the relevant process parameters (temperature, pressure, composition of materials involved in the process);

distribution and mixing valves used for the distribution of flow in certain directions;

safety valves - to protect the facilities serviced by the excessive pressure increase through the issuance of excessive amounts of the working environment;

safety valves designed to protect the equipment from accidental changes in the parameters of the working environment. In contrast to the protective, safety valves in case of emergency conditions is closed and disables serviced land than protects it from harmful influences;

fazorazdelitelnaya massorazdelitelnaya and PEX fittings designed for automatic separation of environments depending on their phase and state.

USA radiators

The advantages of cast iron and aluminum radiators




Gone are the days when the radiators were exclusively iron. Today, manufacturers of radiators offer a wide range of products made from different materials - iron, steel, aluminum and bimetal radiators. Each material has its advantages and disadvantages.
The main advantage of cast iron radiators - their incredible durability and resistance to corrosion. The service life of cast-iron radiators is 50 years old! At the same radiators of this material is not demanding as a coolant for a long time keep warm. If, however, cast iron radiators increased cross-section of water channels, then wear it, as they say, will not.
However, cast iron, as a structural material, has its drawbacks. Among them - not very high heat transfer and a large internal volume. In addition, the iron particles can contaminate the heating system. Given the pros and cons, cast-iron radiators are widely used in the construction of buildings of varying height. Production of cast iron radiators is less expensive, which makes cast iron radiators available for most buyers. And their appearance is much more attractive than in Soviet times. Among the models of cast-iron radiators manufacturers offer products, stylized antique, as well as heating radiators with modern design.
Unlike the cast-iron radiators, aluminum radiators have a high emissivity and low weight. Among the advantages of aluminum radiator manufacturers also produce an attractive and modern look of the material. Aluminum radiators are more expensive than iron, and thus more demanding as a coolant. Therefore, when purchasing aluminum radiator is essential to specify how they are adapted to USA conditions.
However, manufacturers of radiators have found a solution for low-quality coolant. This - bimetal radiators. In the production of radiators of this type of aluminum are inserted water channels from the steel pipe. Therefore, bimetal radiators combine the reliability and advantages of aluminum radiators. Lifetime bimetallic radiators higher than aluminum. In this case, they are less demanding as a coolant, rather than aluminum radiators.
Most aluminum radiators are used in low-rise building, in private homes and cottages.
When buying a radiator, except for technical data, to draw attention to the manufacturer radiator. On the market today are many European and USA companies engaged in production of radiators. The advantages of European manufacturers - modern design and high quality materials. However, manufactured in Europe radiators are often not adapted to Chicagon conditions. Therefore, the reliability to take USA radiators, most of which takes into account the quality of the domestic carrier. Moreover, among USA firms have manufacturers producing radiators, not inferior in design and quality of European counterparts.

PEX fittings

By the application of valves are divided into the following categories:

Industrial valves general purpose manufactured commercially in large quantities and is designed for environments with frequently used values of pressure and temperature. These PEX fittings are equipped with water pipes, steam pipes, municipal pipelines, heating systems, etc. In Chicago, such devices are widely represented products of the German manufacturer ARI-Armaturen GmbH, Polish - Zetkama, Slovenian - POLIX, Chicagon - Corporation Kyiv PEX fittings. This is mainly valves, shut-off and control valves, pressure reduction valves, temperature regulators, safety valves, balancing valves, steam traps.

Industrial valves for special conditions designed to operate at relatively high pressures and temperatures, at low temperatures, in corrosive, toxic, radioactive, viscous, abrasive or granular media. This fixture include: PEX fittings of high energy parameters, cryogenic, corrosive, fountains, valves with heating, valves for abrasive slurries and bulk materials. One of the largest predpriyatiyproizvoditeley in Chicago is the JSC "Ivano-Frankovsk Valve Plant".

Special valves are designed and manufactured for individual orders on the basis of specific technical requirements (eg, for experimental and unique industrial installations, including those for nuclear power plants).

Ship PEX fittings available for work in specific conditions on ships of the river and sea fleet in the light of increased demands on the minimum weight, vibration resistance, high reliability, the special conditions of management and operation.

Advantages of PEX Tubing

Over the years, this type of tubing is offering incredible benefits to users primarily due to its incomparable quality and essential features that define the nature of such tubing systems. Here are some noticeable advantages that have significantly benefitted a large number of users to a great extent.

>> One of the greatest benefits offered by the PEX tubing is unparalleled durability of the material which makes it one of the most long lasting tubing systems. The strength and sturdiness of the material allow people to secure firm connections with minimum fittings for installation process.

>> The tubing offers high resistance against corrosion thereby protecting such tubing systems from getting spoiled or damaged. This is the primary reason that accounts for the diverse usability of the tubing in varied types of applications. PEX tubing therefore offers exceptional utility as compared to several other materials like copper and lead that easily fall prey to such chemical attacks.

>> Unlike other materials, PEX tubing is manufactured through a process of extrusion which significantly reduces several overhead costs. These costs may include storage costs, shipping charges and various handling costs which can be quite problematic for the manufacturer to bear such additional costs.

>> PEX tubing offers incomparable flexibility which is quite a rarity in various other plumbing materials. Owing to their increased elasticity, the PEX tubing can be easily bent and twisted for the purpose of attaining safe and secure connections for easy installations. This in turn makes this type of tubing ideal for its use in a large number of plumbing systems.

>> PEX tubing that is used in a large number of plumbing systems allows smooth and unrestricted flow of water without any noise. This kind of tubing is therefore largely preferred to other materials that are not that effective in such operations.

Amtrol expansion tanks for heating systems

They are used in modern energy-saving heating systems closed. What these systems differ from traditional described in the article "The Evolution of heating systems"

Amtrol Expansion tanks are steel housing with built-in membrane of artificial rubber and are designed to compensate for the expansion of the liquid circulating within the heating system.

Amtrol expansion tanks for heating differ:

*on the maximum allowable working pressure, ie wall thickness of the tank (depending on the operating pressure used type of heating system)
*the type of mounting flange to the tank - removable or fixed membrane (for tanks with small capacity are usually rolled manner of attaching the flange to the tanks of large capacity flange screw, which allows the replacement of membranes)
*the type of rubber - for systems operating on water use heat-resistant rubber SBR, for the systems to use antifreeze membrane of rubber Nitril
*in capacity, which should be specially calculated for each specific system, depending on its internal capacity and power boiler

The design, selection and calculation of the expansion tank for heating

Amtrol expansion tank

Amtrol expansion tank - a product consisting of a metal container containing within the second container in the form of elastic rubber for heating and plumbing supply buildings of varying height.

So far, the function of this apparatus is little known and most consumers are sold without the necessary explanations.
In this text we want to explain the need, and emphasize the importance of its function and why did not need to look for other solutions, leading to unjustified material costs.

The first chapter, we shined on "expansion tanks for heating systems"

Evolution of heating systems.

The old heating system housing using natural circulation of hot water, which is used to support piping of suitable diameter, the large size of which decreases with time, and more and more increasing distance from the boiler to the radiators.
