With the enhancement of people's awareness of environmental protection, the requirements for building water supply and drainage are higher and higher, and various new structural PVC-U pipes came into being. Its functions and characteristics are different.

Polyethylene of raised temperature resistance, abbreviated as PE-RT. As a new type of plastic pipe, PE-RT pipe has become the main force in building hot water system and floor heating system, especially in floor heating pipe system, with its long-term hydrostatic strength, temperature resistance, pr......

Because the floor heating pipe is a coil, a bundle of 200-300m, the deviation of the middle pipe is not easy to find, and there will be potential quality problems. PE-RT pipe production requires that the good properties of the raw materials be "duplicated" to the pipes, and it is hoped to realize co......

Process flow: granular raw material → drying → extruder heating → special die for PE-RT pipe → vacuum calibrating tank → cooling tank → printing → high-speed haul-off → chip free cutting machine → coiler → inspection of appearance and size → simple packaging → pressure test → packaging after passing......

According to the raw material characteristics of PE-RT pipe, the length diameter ratio of the screw is relatively large, which is usually designed as 33:1. The double-stage mixing screw is adopted in the screw structure, and there is a mixing element in the middle and head of the screw to avoid exce......

The US plastics industry saw increased trading in the first six months of this year – but with imports far exceeding exports. Figures in the Plastics Industry Association’s Global Trends report reveal that trading volume exports plus imports – rose by nearly 28% for the first half of the year, ......
