Introduction: Cross helically wound steel wires reinforced PE composite pipe is a kind of composite pipe, which is made of HDPE as matrix, steel wire wrapped with adhesive resin as reinforcement and connected with matrix by adhesive resin. The bonding resin becomes the common bonding factor between steel and HDPE, which gives the composite pipe excellent mechanical properties.

Product parameter: Specifications

Standard: GB/T 32439-2015 《Cross helically wound steel wires reinforced-polyethylene composite pipelines for water supply》

CJ/T 189-2007《Steel wire reinforced thermoplastics (PE) composite pipe and fitting》

Product advantages:

● The products are characterized with low linear-expansion coefficient and creep resistance similar to steel pipe, and with the strength, rigidity shock strength exceeded plastic pipe.

● The corrosion resistance of the pipe is as the same as plastic pipe, but the temperature resistance and the thermal conductivity is lower than plastic pipe.

● The structure of the pipe is excellent: the body of intensifier layer is placed between the plastic layers with the special technology so there is no worry about peeling off each other.

● The products can overcome the problem of the rapid stress crack of plastic pipe. Because of the compound structure of the steel and the plastic materials, the rapid stress crack phenomenon will not occur.

● The inner wall of the pipe smooth and dirty free, the delivery water-head loss of the pipe is about 30% lower than steel pipe.

● The kinds of the pipe with different pressure degree can be manufactured by adjusting the diameter and quantity of steel wire. Light weight and easy installation; various specification and type of the pipe joints are all in readiness and the connection technique is mature and credible. The pipe connection adopts electric tie-in, and tension ability of connection is stronger.

● The pipe can be connected to various pipe, vale and equipment.

● Possessing high reliability, the service life of the pipe can be lasted for over 50 years under normal condition. With preferential price, good performance and non-toxic characteristics, it is the best one to take place of steel pipe, nodular graphite pipe and pure plastic pipe.
