DHPI-Composite Pipe Manufacturer

Are you looking for durable, high-quality, and affordable composite pipes?  DHPI SRTP composite pipe will be your perfect solution.


SRPE composite pipe is steel wire reinforced polyethylene (SRTP) pipe that could be used in water supply, sewage drainage, and even in the deep sea because of its high-pressure porous material.  It uses HDPE resin as the raw material for the inner and outer coasting to ensure the water is non-toxic.  And the middle layer uses the adhesive resin to ensure that the pipes are integrated without stratification.For application, SRTP has very strong properties.  It combines the characteristics of PE pipe and steel pipe.  Not only does it have the corrosion resistance, long service life, and good flexibility of PE pipe, but it also has the strength and stiffness of steel pipe. So SRTP pipe can adapt to various extreme environments that might not be stalled conveniently, such as mountain areas, the bottom of the sea, and areas prone to earthquakes.  It is absolutely the perfect product you can choose.


We, DHPI is the biggest manufacturer of steel reinforced polyethylene (SRTP) composite pipe, have been producing this kind of pipe for 27 years.  Our product is used in China very widely.  And we have the capability to undertake large projects, such as the North Water Transfer Project (our national project) from 2017;  the pipe has been safe applied for 9 years.


We are not only a pipe manufacturer, but we also prove the integrated solution to your questions.  We hope to build a great relationship for your easy purchase of your next project.
