SSJB Mechanical pipe coupling, also called flexible coupling, flexible pipe coupling, slip on coupling, mechanical coupling, dresser coupling, type 38 coupling and others. Mechanical pipe coupling is made up of follower, sleeve, rubber seals and other components. This type coupling's function is similar with rigid coupling, connecting two pipes, without welding or flange, only screw the bolts and nuts, the rubber seals will prevent leakages. At the same time, there will be some movements. SSJB gland loosing expansion joint Europe standard: BS EN 10311-2005.

Classification of SSJB mechanical pipe coupling:

1. According to the material, there are 3 types of mechanical pipe couplings.

(1). Carbon steel mechanical pipe coupling. It can be divided into two type, their difference is the Follower, first type Follower is similar with welded neck flanges; second type Follower is similar with slip on flanges, the thickness is different, their function basically the same, can replace each other.

(2). Ductile iron mechanical pipe coupling. 

(3). Stainless steel mechanical pipe coupling.

2. According to whether concentric, there will be concentric coupling and eccentric couplings. Eccentric couplings also called step coupling.
