Steel Braid Reinforced Plastic Clad Pipe,structure and features
Product Presentation
Steel mesh skeleton of polyethylene plastic pipe is coated with high strength copper coated steel wire Continuous winding core layer is raised strong skeleton, with high density plastic (PE) as basic materials, using a professional hot melt adhesive (high-performance modified polyethylene adhesive resin), on the production line Through continuous times, extrusion molding plastic composite pipe.
It is widely used in long-distance buried water supply and drainage pipeline system, and it is the first choice to replace steel pipes and other traditional pipes in China.
Product Property
1, with more than plastic pipe strength, rigidity, impact resistance, similar to steel pipe low linear expansion coefficient and creep resistance and other advantages, with the same corrosion resistance of plastic pipe, and the use of high temperature and corrosion resistance, low thermal conductivity.
2, the inner wall is smooth and the pipe wall does not scale, the transmission resistance is small, the same inner diameter of the water can increase the flow of 30% than the steel pipe.
3. Excellent wear resistance is 4 times that of steel pipe.
4, long service life, in the standard state, at least 50 years of safe use.
5. Excellent structure. The reinforcement skeleton and inner and outer layer of the pipe are mutually contained into a whole, without the worry of the inner and outer layer of the plastic and the reinforcement body.
6, excellent toughness, because the steel and plastic two materials are composite structure, will not occur plastic pipe difficult to overcome the phenomenon of rapid stress cracking, even if the pipeline is difficult to crack serious deformation, so its earthquake resistance is very good.
7. The pipeline is light in weight and flexible, with excellent construction performance and low construction cost. Pipe connection adopts electric hot fusion joint, strong axial tensile resistance, mature and reliable connection technology, complete pipe fittings and specifications, can be connected with other kinds of pipes, valves, equipment.
8, through adjusting the diameter of steel wire, steel wire root number, manufacturing pipeline of different pressure grades.
9, comprehensive cost-effective, safe and non-toxic, is the best substitute for steel pipe, spherical ink pipe and pure plastic pipe.
Technical Requiremen
The color is usually black, or it can be decided by both parties through negotiation. The inner and outer surfaces of the pipe should be smooth and smooth, allowing small pits and bumps with natural shrinkage, and not allowing bubbles, cracks, discoloration and obvious scratches. The two ends of the pipe should be cut smoothly.
Operative Norm
The sanitary index is in line with the provisions of GBT17219-1998 "Safety evaluation index of drinking water transmission and distribution equipment and protective materials". Product standard conforms to CJ/T189-2007.
Nominal OD,Pressure,Wall Thickness and Limit Deviation for Pipes for Water Supply,Special Fluid
Description:
1, product implementation standard: CJ/T189-2007 "steel wire mesh skeleton plastic (polyethylene) composite pipe and fittings"
2. The diameter of steel wire and mesh parameters are different for composite pipes with different pressure levels in the same specification; For special working conditions, both parties will negotiate separately.
3. Nominal pressure is the maximum use pressure of pipe conveying water medium under 20P. If the medium temperature changes, should be corrected.
4, the color of the pipe is generally black, and the buyer and the seller will agree separately when the user makes special requirements.
