Classification of SSJB mechanical pipe coupling:

1. According to the material, there are carbon steel, ductile iron, stainless steel mechanical pipe couplings.

1) Carbon steel mechanical pipe coupling:

Our company's carbon steel mechanical pipe couplings can be divided into following two type, their difference is the Follower, left photo Follower is similar with welded neck flanges; right photo Follower is similar with slip on flanges, the thickness is larger than left photo's, their function basically the same, can replace each other.

2) Ductile iron mechanical pipe coupling. Please check following different mechanical pipe couplings photos:

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.
