US plastics sector rises in first half as trade deficit increases

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, ......

Design of screw barrel of PE-RT pipe extruder

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......

Process control of PE-RT pipe extrusion production

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......

PE-RT pipe extrusion equipment

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......

Overview of high speed extrusion production of PE-RT floor heating pipe

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......

Performance Characteristics of Various PVC-U Pipes

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.
