Hot Water Reinforced Plastic Pipe 15mm 2.8mm DN25-DN400

Grade:Hot Water
 
Product:With The Inner Stainless steel Ring Plastic-Steel Composite Panel for Hot Water
 
Decriptions
 
All steel and plastic pipe products base pipe raw material galvanized steel pipe internal burr must be removed, each pipe inner wall using polishing equipment for 360° no dead corners to remove the obvious internal burr and zinc slag, zinc tumor, etc., roughness in line with the national lining plastic standards. The bond degree of plastic layer and steel layer reaches 98%. Completely replaced the old inner wall sandblasting process. The internal burr of galvanized steel pipes for all inner ring steel pipes must be removed. The company is using independent research and development and apply for a national patent "a double screw pipe wall polishing equipment" (patent no.: ZL201721080676.1), can within 15 seconds to pipe wall dirt and oxidation cleaning, after polishing treatment, get a certain roughness and smooth surface, enhance the bond of pipe and PE, improve the quality and corrosion effect. There is no obvious zinc slag, weld and legacy in the pipe, and the weld height shall be less than 0.1mm.
 
With the inner stainless steel ring plastic-steel composite panel is combination with PEX pipe and Hot dip galvanized steel pipe and the inner stainless steel ring. It is used by constant pressure and high temperature composite technology,ensure the inner plastic pipe in good shape and bonding the steel pipe well,without glue cracking and shrinking issues happening. The hot DIP galvanized steel pipe is adopt the international leading high-frequency new welding technology,and galvanized with high quality 0 pure Zinc plating. 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.
