DONGHONG Pipe Industry is the top 10 largest PE pipe manufacturer, we have the capability to make 300000 ton PE pipe each year, the raw materials are imported from all over the world, mainly from Korea and advancement equipments from Germany. We have more than 2000 employees. Our products  have passed the ISO 9001 AND ISO 14001 Standards. Our new product "Steel mesh reinforced composite PE pipe"-"RTP" is a new technology imported from Taiwan, this product has more benefits than PE pipe.

 

 

Steel Wire Reinforced Composite Polyethylene (SRTP) Pipe

 

Product Structure

Taking high strength steel wires coated with adhesive as the reinforcement between inner and outside composite thermoplastics, this product series is a new style of low, medium and high pressure resistant composite pipes. Because the reinforcement is wrapped into continuous thermoplastics, this kind of composite pipes not only overcomes defects of both steel and plastic pipes, but also possesses their common advantages. It's a revolutionary technical outcome not only for construction and municipal water supply pipelines after galvanized steel pipes are forbidden, but also for strong demand for large diameter rigid pipes from industrial fields like oil, petrochemical, pharmacy, food, mining and fuel gas, etc. Corresponding fittings of steel wire reinforced thermoplastic composite pipeline are electro-fusion fittings. Fusion of the pipeline outside plastic surface and the fitting inner plastic surface will be reached through the internal heating unit of the fittings in pipeline connection, thus they can be connected firmly.

 

Product Characteristics

• It's properties of strength, rigidity and shock resistance are better than that of plastic pipes.
• double-faced anticorrosion: It has the same anticorrosion property with plastic pipes.
• raised working temperature; low thermal conductivity; heat preservation for outer surface of pipe not needed in winter and no dewing in summer.
• Smooth inner surface and non-scaling make head loss lower than steel pipes by 30%.
• Mature electrofusion connection technique is adopted in pipeline connection; Electrofusion fittings have complete types and specifications, and the joints have strong resistance to axial tension.
• Light in weight, thus it is convenient to transport and install; integrated reliability of this pipe line is high; its service life could reach 50 years under normal working conditions.
• Due to its advantages of low cost, health and non toxic, it is the best substitute of galvanized steel pipes.

Technical Requirements

 

Common color is black and other colors are available by joint negotiation between supplier and buyer. Inner and outer surface of the pipes should be smooth. Natural shrinking tiny pits and bulges are allowed while air bubble, crack, decomposition allochromasia and obvious scratches are not allowed. Pipe ends shall be cut flat.
