The chemical name of hdpe pipe is high-density polyethylene, which is a thermoplastic resin. HDPE Pipe have very high crystallinity, non-polarity, and excellent electrical conductivity, so they are widely used in wires and cables.
When selecting a HDPE pipe, first look at the shape to see if there is any deformation, whether the surface is smooth enough, and whether the color is uniform.
The wear resistance of hdpe pipe is very good, its shear strength is very high, and its crack resistance is very outstanding. According to the data, the wear resistance of hdpe pipes is better than that of steel pipes, even four times higher, which means that the service life of hdpe pipes is also longer.
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.
HDPE Dredge Pipe should not only have good economy, but also have more stable and reliable interface, better material impact resistance, crack resistance, aging resistance and corrosion resistance.
The hot melt welding machine adopts drawing plate structure and electric heating method.
