The quality of Uniplastic pipes is very good.
The pipe is the material used to make the fittings. Different fittings to use different pipe, the pipe directly determines the quality of the fittings. Construction projects, power plants, chemical plants and other such pipe, there is the implementation of the standard GB/T5310.
Used in high-pressure boilers: there is the implementation of the standard GB/T8163; seamless steel pipe for the transmission of fluids: there is the implementation of the standard GB3087; low-pressure boiler seamless steel pipe: there is the implementation of the standard GB/T9948.
Selected materials:
PPR pipe using triple-propylene polyethylene as a material, has a moderate price, heat and corrosion resistance, stable performance, not scaling, the use of life can be up to 50 years, etc., can be embedded in the wall, or deep wells pre-buried. But the construction technology requirements are high, need special tools and professional understanding of the construction in order to protect the safety of the system.
PVC pipe is the world's favorite, popular and widely used a pipe, it has good processing performance, low manufacturing costs, insulation, corrosion resistance, etc., can be used as a water supply fittings for the building water supply project or sewage.
For HDPE pipe, it uses the material is very high crystallinity, non-polar thermoplastic resin made of a kind of pipe, the surface course of milky white, can be corrosion-resistant to most of the life and industrial chemicals.
