Stainless steel coupling is a short pipe component used to connect two pipes or pipe sections in a straight line. It is mainly divided into two types:

• Equal Coupling: A product with the same thread size at both ends, used to connect pipes of equal diameter
• Reducing Coupling: With different thread sizes at both ends, used to smoothly transition a larger diameter pipe to a smaller diameter pipe

This pipe clamp is connected with NPT (American standard pipe taper thread), with a tooth angle of 60° and a thread taper of 1:16, which can form an effective mechanical seal when tightened. This connection method does not require welding, and installation and disassembly are very convenient. It is one of the most common connection forms in industrial and civilian pipelines in North America and globally, and is highly cost-effective and flexible.

304 stainless steel (cast as CF8) is the most widely used and cost-effective stainless steel grade. It exhibits good corrosion resistance in water, air, and various weakly corrosive media, effectively preventing rust and ensuring the cleanliness of fluid media. Its excellent mechanical properties and ease of processing make it an ideal material for manufacturing low-pressure pipe fittings in fields such as water supply and drainage, general chemical engineering, etc. It combines reliability and economy.

Class 150 cast pipe clamps are the basic components used to connect straight pipe sections in low-pressure piping systems. They are widely used in commercial and residential water supply and drainage systems, fire pipelines, and general industrial utilities such as compressed air and waterways. Pipe clamps, with their simple and reliable design, provide an economical and efficient connection method for constructing long-distance, continuous straight pipe sections using standard length pipes.
