Heat shrinkable belt type sleeve joint
Heat shrinkable belt type sleeve joint is made by special import heat shrinkable belt, through the flame heating contraction, make the tight connection of the HDPE outer protection pipe and the joint sleeve, not only ensure the sealing of joint and water proofing property, and can absorb the axial displacement of the pipe, it requires simple equipment and instrument and it really convenient and practical for small diameter pipeline.
Electric welding type socket connectors
Sleeve joint with electric welding is through special plastic welding equipment to heat the wire in the polyethylene casing, by heating and a certain pressure, make joint casing and polyethylene outer pipe as a whole system.
Welding tensile strength of the joint is not lower than the shell material, it is stable and reliable, easy to operate, and can do 100% air test.
Adopting professional electrical control box to make automatic control of heating process, through the control of the different process parameters, optimal melting effect, so as to ensure the quality of welding joint and sealing, and deliver higher axial force.
