When installing plumbing pipeline

1. Installation of PEX plumbing pipeline mainly on butt welding. Flange connections to put only where adherence to the connecting pipes, fittings and plugs, as well as material lines, where it is necessary for the installation conditions.
2. Laying PEX plumbing pipeline must be made at elevations specified in the installation drawings, while liquid PEX plumbing pipe should be installed in compliance with slopes that provide fluid flow during transportation. Gradient, is taken within 0,002-0,005.
3. Fixing plumbing pipeline carry on hangers, brackets, braces or other types of steel, fabricated on site. The distance between the supports to take: for steel plumbing pipeline 2-4 meters for non-metallic plumbing pipeline 1-2 pm
4. Fixture on the non-metallic plumbing pipeline mount separately to plumbing pipeline did not experience additional load.
5. The distance from the axis of PEX plumbing pipe to the wall in mm taken depending on the nominal bore in mm
6. The smallest radius of bending pipes allowed:
a) for bending of tubes with padding it with sand and heating at least 3.5 outer pipe diameters;
b) for bending of tubes on the machine without packing sand (cold) not less than 4.0 outer diameter pipe;
c) for a plumbing pipeline when the bending radius of less than 2.5 outer diameters of pipes and plumbing pipeline with a nominal bore exceeding 100 mm manufacturing the knee bends and welded from individual sectors.
7. When connecting pumps and devices mount plumbing pipeline to produce such a way that the weight of plumbing pipeline and fittings are not transmitted to the pumps.
