buckling-type pipe connector pipelineinstall easy to connect, effectively improve further
pipe jointbearing capacity and corrosion resistance.
4., because being respectively respectively equipped with the O RunddichtringO that twice and tubing base layer inwall coincide on pipe joint inner core I and pipe joint inner core II, exist again
withholdinner core I He
withholdthe concavo-convex socket joint position of inner core II be provided with
withholdthe y-type seal ring that inner core II inwall coincide, forms multiple-sealed structure thus, effectively prevent the intrusion of various source of corrosion, guarantee
pipe joint andbody is not corroded, and effectively extends pipeline working life.
5. because of
withholdinner core I He
withholdthe position, termination that inner core II is connected be provided with
withholdthe concavo-convex thread bush be connected together in the termination of inner core I, without the need to thermal source, without the need to main equipment, work under normal temperature operating mode, installation and maintenance are extremely convenient.
