HDPE Butt Reducing Coupling

When connecting with hot melt, the voltage is required to be between 200~220V. If the voltage is too high, the heating plate temperature will be too high, and the voltage will be too low, and the docking machine will not work normally; the interface should be aligned during the docking, otherwise it will cause Insufficient butt joint area, insufficient weld strength, and improper crimping; the pipe joints are not cleaned when the heating plate is heated, or the heating plate has impurities such as oil and sand, which will cause the joint to detach and leak; the heating time must be controlled Good, short heating time and insufficient heat absorption time of the pipe will cause the weld edge to be too small, and the heating time will be too long, which will cause the weld edge to be too large, possibly forming a false weld.

Features

High-density polyethylene is non-toxic, tasteless, and odorless white particles with a melting point of about 130°C and a relative density of 0.941 to 0.960. It has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. Dielectric properties and environmental stress cracking resistance are also good.
