HDPE silicon-core pipe is a kind of communication optical (electric) cable protection tubing, which is produced and shaped through extruding synchronistically the silicon-core material with low friction coefficient inside HDPE pipe. Thus the HDPE silicon-core pipe provides the convenience for the cable laying because of the lubricating solid tunnel with durability and lower frication coefficient. It becomes the most advanced optical cable protection in world at present. Its advancement is presented on the replacement of cable personal pulling. The cable-blowing machine will blow the cable into the lower friction HDPE pipe and the cable goes forward at high speed in the suspension state. This cable laying way avoids the cable damages caused by the pulling. The cable blown once can reach more 2000 meters. For that, the accidental signal loss caused by machine pulling has been reduced greatly and the too many knots resulted from the pulling length limitation has been decreased greatly. At the same time, the well digging quantities have been minimized and the project cost has been saved. The HOPE silicon-core pipe has the high intensity, excellent property resisting high or low temperature, adaptability for steepness and bending changes.

Early or late, Mingzhu Company has introduced eight extruding product lines reached international advanced level. The product lines have been equipped with online test system for the pipe wall thickness. The real time inspection and control for the wall thickness guaranteed the quality's stability. In addition to more than 1,300,000 meters pipes with all specifications, the gas pipes production capacity has reached 50,000 tons per year. The output and sale volume take the first position at domestic in present.

The PE water supply pipe is extruded by the extruding product lines with special purpose polyethylene material. The pipes apply to cities and towns water supply pipeline net, irrigation and channel water project, garbage treatment site, sewage collecting pipeline project and agriculture spray irrigation project. Because the PE pipeline adopts the thermal fusion and electric fusion connection technologies, the interface has been integrated and the pipeline can resist the hoop stress and axial shock resistant stress produced by inside pressure. In addition, the PE pipe does not contain the heavy metalsalt stabilizer. The second pollution for drinking water is avoided for the pipe material no toxic, no pipe scale and not breeding bacteria.

Special,stucture,high intensity, excellent airtight property, no leaking.
Anti-corrosion treatment for the metal part, be durable.
The metal part can be made of copper or stainless steel etc according to the customer's requirement.
Mingzhu company's electrofusion fittings adopt international advanced techniques
Adopting special purpose material for PE pressure pipeline
Special mould design guarantee the precision and stability for the pipefitting size
Adopting the auto-coiling tech to guarantee the heating wire's average tension force, to reach stable quality and get the fine welding effect.
Concealing the heating wire can improve the fittings' resistance for external force shock greatly. And avoid the short circuit due to extruding by the heated PE material flow.
The welding effect can be observed by the observation hole
The bar code includes the optimum parameters and provides the convenient welding method.
