The welding of HDPE impermeable film uses wedge welder and double track hot melt welding. Wedge welder can not weld parts, should be used extrusion hot melt welder, with the raw material homogenous electrode, forming a surfacing single weld.
The hot melt welding machine adopts drawing plate structure and electric heating method.
HDPE is a good pipeline, not only should have good economy, but also should have a stable and reliable interface, material impact resistance, cracking resistance, aging resistance, corrosion resistance and a series of advantages, compared with the traditional pipe, HDPE pipeline system has the following series of advantages:
Ningbo Sunplast Pipe Co., Ltd has been focusing on manufacturing of plastic piping systems for more than 15 years. We started the business as a micro factory which had less 5 workers & only one extrusion line for 20-315mm HDPE pipe, but now, we have been growing to be a modern international factory owning three manufacturing workshops & more than 200 workers. Equipped with world advanced pipe extrusion lines and injection machines, the company’s annual output of plastics reaches over 15000 tons.
Hdpe tube is a kind of pipe made of High Density Polyethylene (English name is "High Density Polyethylene", referred to as "HDPE").
PPR pipe specifications are expressed by tube series S, nominal outer diameter DN × nominal wall thickness EN
