HDPE Elbow Fittings

Description

This HDPE Elbow Fittings is a product used to connect pipes.The elbow fitting allows you to change the direction of the pipe at a 90 or other degree angle.Its own coupling can help you quickly connect to the pipeline and is safe and stable and will not easily burst.Compared with traditional pipes, it has significant advantages such as light weight, corrosion resistance, low water flow resistance, energy saving, simple and rapid installation, and lower cost, and has been favored by the pipeline engineering community.

Characteristic

High-density polyethylene has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. Dielectric properties and environmental stress crack resistance are also good. Hardness, tensile strength and creep are better than low density polyethylene; wear resistance, electrical insulation, toughness and cold resistance are better, but slightly worse than low density insulation; chemical stability is good, at room temperature Under certain conditions, it is insoluble in any organic solvent, resistant to corrosion by acid, alkali and various salts; the film has low permeability to water vapor and air, low water absorption; poor aging resistance, environmental cracking resistance is not as good as low density polyethylene, In particular, thermal oxidation will reduce its performance, so the resin needs to be added with antioxidants and ultraviolet absorbers to improve and improve this deficiency. The heat distortion temperature of high-density polyethylene film under stress is lower, which should be paid attention to when applying.

Application

HDPE pipes and fittings like this HDPE Elbow Fittings are mainly used for: municipal engineering water supply systems, building indoor water supply systems, outdoor buried water supply systems and residential communities, factory areas buried water supply systems, old pipeline repairs, water treatment engineering pipeline systems, gardens, irrigation and other industries Water pipes, etc. And they are indispensable parts.The interface part requires high dimensional accuracy. Although 80 percent of plastic products are formed by injection molding, this is usually formed by extrusion process.It is difficult for most of the injection molding process to meet the dimensional accuracy requirements of elbow fittings.Our products take mold cavity temperature and compression time as important parameters of the extrusion compression process. Through continuous technological improvement, these two process parameters are optimized to solve problems such as poor dimensional accuracy of pipe fittings so as to ensure the production of high-quality products in large quantities.
