Slip type expansion joint, also called tubular expansion joints, slip type expansion connector, is a kind of hot fluid pipeline compensator.
It is mainly used for straight pipes, and suitable for hot water, steam, oil medium, through the sliding movement of the sliding sleeve external sleeve, achieve compensation of thermal expansion. Slip type compensator is suitable for the medium pressure 2.5 MPa or less, the medium temperature and 40 ° C ~ 600 ° C.
Slip type expansion joint uses new sealing material, the flexible graphite ring, which with strong strength and low friction coefficient (0.04 ~ 0.10).
The service life of the slip type compensator is long, fatigue life is the same with pipeline. Sliding surface through special processing, in salt water and salt solution environment, corrosion resistant performance is good, more than 50 times higher than austenitic stainless steel.
Slip type expansion joint for chloride ion content requirements, especially suitable for medium or environment excess chlorine ion system, sleeve type compensator is one-way and two-way compensation structure, bi-directional type is characterized by whatever medium from compensator inflows, the sliding sleeve are always free at the ends of the expansion joint, achieve two-way compensation function, increase the amount of compensation. Buried slip type expansion joint can directly be buried underground, installation time is not set up maintenance well, low engineering cost.
