1.Heat shrink tape
When connecting by this method, the casing of the joint should be made of polyethylene and have the same density as the insulation pipe to ensure the sealing of the joint. Then foam is performed on the joint casing. After the foaming is completed, high-density polyethylene is used for sealing, and finally the sealing is continued by welding.
2. Electric heating fuse
This welding method requires a sleeve embedded with resistance wire, tightly wrapped around the hot-melt sleeve in the housing with a binding tape, and then the power is turned on. The welding time needs to be preset, and the welding stops after the power is turned off, and the sleeve is completely Cool, using this connection, welding is very safe and easy to operate.
