Slip type expansion joint also called as tubular expansion joints , pipe expansion connector, it’s a compensation device for thermal fluid pipeline. It is mainly used for straight pipe linings, 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 expansion joint is suitable for the medium pressure 2.5 MPa or less, medium temperature within 40 ℃ ~ 600 ℃.
Product features of slip type expansion joints:
- Slip type expansion joint uses new seal material flexible graphite ring, with strong strength, low friction coefficient (0.04 ~ 0.10), not aging, effect is good, convenient maintenance, etc.
- The service life of the slip type expansion joint 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.At the same time, the sealing effect caused by abrasion wears off after so many years, but again the fastening flange, strengthens the sealing performance, can also will loosen bolts in press circles, then into a layer or two layers of sealing ring, clamping pressure circle, continue to use.
- Slip type expansion joint is suitable for chloride ion content requirements, especially suitable for medium or environment excess chlorine ion system.
- Slip type expansion joints have single direction and bi-directional compensation structure, bi-directional type’s feature is that the expansion joint can achieve two-way compensation function, no matter the medium enter any end and increase the amount of compensation.
- Buried slip type expansion joint can be directly buried underground, maintenance well is not necessary, low engineering cost.

1.Slip type expansion joint has large compensation amount. It won’t generate blind flange thrust or internal pressure thrust, no instability and water hammer. In appearance design, the thrust can be ignored, since it has little effect on the fixed support, thus, fixed support and concrete foundation can be smaller to reduce engineering cost.
2.Slip type expansion joint employs unique sealing technology and most advanced sealing material, unique operation mode enables very slight abrasion, no leakage, no need to change sealing material in 15 years.
3.Other compensator has disadvantages of small compensation amount, low safety performance, inconvenient to maintain, especially used in city underground pipe network. Choosing Lanphan slip type expansion joint, you can lay a long distance pipeline(no need to install expansion joints within 1000m), our products can reduce hydraulic resistance, reduce loss of pressure, reduce cost reduction, also save project cost for 20% to 30%.
4.Safe operation in condition of high temperature and high pressure.
5.Easy to maintain: available for maintenance with temperature and pressure.
6.Convenient to design: in condition of large axial displacement or axial thrust, and pipe network structure needs to be adjusted, applying vertical pipeline structure can obtain larger compensation amount and balanced capacity, also able to change pipeline direction according to pipeline network structure, only need to calculate its force of friction.
