Types of Stainless Steel Coupling
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
NPT Threaded Connection
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.
Material Properties of 304/CF8
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.
Application of Stainless Steel Casting Coupling
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.
