50mm Steel Plastic Composite Pipe 3.8mm For Water Supply Pipeline System

Grade:Hot Water

Product:With The Inner Stainless steel Ring Plastic-Steel Composite Panel for Hot Water

Decriptions

The plastic pipe is used by high quality and 100% virgin PE,which meets the standards of food hygiene and drinking water.The hot melt adhesive resins are good quality,high purity with excellent bonding strength,ensure the bonding strength between the steel pipe and plastic pipe. The plastic-steel composite pipe head is fixed the inner 304 stainless steel ring,which is national patent products. The inner stainless steel ring perfect resolves the separated problems between the plastic pipe and steel pipe,for which the expansion and contraction happens, or the flow water impacting the pipe head for long time. The revolutionary technology can protect the water quality well,meanwhile elongates the pipe service life greatly and makes price competition. The big size pipes form DN-200 to DN400 are used by same technology as small size pipes, which is hard to achieve by most of other companies.

Installation and connection Method

1. Groove connection

a. Select a Standard-Compliant Grooved Fitting;

b. The working pressure of the grooved pipe joint should match the working pressure of the pipeline;

c. Select the rubber sealing ring of the composite drinking water standard, and the hot water pipe adopts the temperature-resistant rubber sealing ring.

2. Threaded connection

a. Choose the Threaded Fitting that meets the requirements;

b. The plastic-lined pipe shall not be directly connected with the valve, and a special transition pipe joint with internal and external threads of brass lined with plastic shall be used;

c. The plastic-lined pipe shall not be directly connected with the water supply spigot, and a special brass inner thread pipe joint shall be used;

d. Special transition joints should be used when connecting plastic-lined pipes with copper pipes and plastic pipes;

3.Flange connection

a. When the working pressure of the pipeline system is greater than 1.0Mpa and less than 2.5Mpa, flange connection can be used;

b. The pressure level of the flange matches the working pressure of the pipeline;

c. Rubber gaskets are used for flange gaskets. When large-diameter gaskets need to be spliced, they should use oblique lap joints, and no flat joints.
