PVC water supply pipe with the health grade PVC resin as the main raw material, adding stabilizer, lubricant, quantitative filling agent, hyperchromic agent by extrusion, injection molding and injection molding machine of plastic extrusion molding machine, through a water cooling, curing, finalize the design, inspection, packing and other processes to produce the pipe.

GOST 3262-75 Water Pipes for Water-supply and Gas-supply Steel Pipes


PVC water supply pipe size of the phi 20, Phi 25, Phi 32, Phi 40, Phi 50, Phi 63, Phi 75, Phi 90, Phi 110, Phi 125, Phi 140, Phi 160, Phi 180, Phi 200, Phi 225, Phi 250, Phi 280, Phi 315, Phi 355, Phi 400 etc.. PVC is shown to the pipe pressure is represented as the nominal pressure, denoted by Mpa. Nominal pressure is 0.63Mpa, 0.8Mpa, 1.0Mpa regulation, 1.25Mpa, 1.6Mpa 5. Each pressure zone minimumGOST 3262-75 Water Pipes for Water-supply and Gas-supply Steel Pipes: minimum diameter 0.63Mpa pipe is 63mm, the minimum diameter 0.8Mpa pipe is 50mm, the minimum diameter 1.0Mpa pipe is 40mm, the minimum diameter 1.25Mpa pipe is 32mm, the minimum diameter 1.6Mpa pipe for 20mm and 25mm. Pipe length is generally 4m, 6m, can be reached by both supply and demand.

The main features:

1 light, handling convenience: smaller density, handling, loading and unloading, convenient construction.

2 excellent corrosion resistance: excellent acid and alkali resistance, corrosion resistance, for the chemical industry’s use is suitable for.

3 small fluid resistance: the inner wall of the pipe is smooth, the roughness coefficient is only 0.009, small fluid resistance, effectively improves the hydraulic condition of the pipe network, reduce the system operation cost.

4 high mechanical strength: pipe has good pressure resistance, impact resistance and tensile strength.

5 simple construction: pipeline connection construction quickly and easily, low cost of construction engineering.

6 low cost: the price is low, and transportation, convenient construction, long service life, so the overall low cost.

7 did not affect the water quality: by the dissolution test confirmed that does not affect the water quality, suitable for popularization and application in large area.

The scope of application Gost8733 Gost8734 Carbon Steel Pipes:

1 Industrial and civil building indoor water supply, water system;

2 live buried in residential water supply system, plant;

3 of urban water supply pipeline system;

4 water treatment plant pipeline water treatment system;
