SSJB(AY) Dismantling Expansion JointGland Loosing Expansion Joint

SSJB(AY) Two End Covers Type LappedSteel Expansion Joint

Two end covers type lapped steel expansionjoint at both ends are covers, in the cover channel is trapezoidal sealingring, after the pipe insert into the sleeve, just tighten the connection bolt；Sealing ring without leakage, no welding,easy installation;Consist of two covers, sleeve, two sealing rings andconnecting ties. The only difference between SSJA type is that one end of SSJAis cover, the other end is flange;

metal Bellows Expansion Joints

Composed of ametal bellows and flange, which can compensate for thermal and mechanicaldeformation, and absorb a variety of mechanical vibrations, to reducedistortion and prolong the pipeline’s service life; To compensate thepipeline’s axial, lateral and angular displacement caused by thermal expansionby metal bellow’s expansion and migration, large compensation, good elasticity.

Technical data:

Material:Carbon Steel, Stainless Steel, Ductile Iron

Workingpressure：0.1-2.5 Mpa

NominalDiameter: D100-D3000mm

Fatigue life:1500 Times

ApplicableTemperature:-20℃~+450℃

ApplicableMedium: Air, compressed air, water, sea water, oil, acid, alkali, etc.
