Wesupply series of stainless steel expansion joint, rubber expansion joint,rubber couplings and dresser sleeve coupling, which is needed to be used in thedrilling fluid & solid control system.
FlexibleRubber Joint (Single Arch) Rubber Expansion Joint
A kind of rubber coupling with goodelasticity, high air tightness, good shock absorption and noise reductioneffect to be used for pipeline with high pressure and large displacement, easyinstallation;
Adopt new technology of gas blowingmold, the rubber sphere made of inner & outer rubber layer, Nylon fabriclayer and steel wire reinforcing ring; No gaskets required, integral rubberflanged design, Flange adopted according to DIN PN16/10, ANSI 150/250/300 lbs.,BS, JIS 10K.
•Face to Face: 6” on sizes 2”- 8”. 8” onsizes 10”- 12”
•End Connections: ANSI 150 Flange xFlange
•Materials: Buna (Nitrile), EDPM, orViton®
•Other sizes available upon request
•Application: Allows movement tocompensate for expansion or contraction that result from temperature changes.Reduces vibration and pulsation.

Metal Expansion Joint Dismantling joint
SSJA(AF) Dismantling Expansion JointFlange Loosing Expansion Joint
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;
