Stainless steel clamp is a fastener used to connect pipes of different diameters. It is often used in locations where the pipe diameter needs to be changed in the pipeline system. It is made of stainless steel material and has the characteristics of corrosion resistance, high strength, and long life, which can meet the use requirements in different environments. The main body of the stainless steel clamp is divided into two parts, upper and lower, which are connected by bolts or nuts. The inner wall of the clamp has a groove design, which cooperates with the sealing ring to achieve the sealing effect at the pipe connection. The opening sizes of the two ends of the clamp are different. One end matches the larger pipe diameter and the other end matches the smaller pipe diameter. The middle transition section presents a conical or stepped structure. Some models of clamps have reinforcing ribs on the outside to improve the pressure resistance.
