Stainless Steel Half Couplings are usually made of stainless steel material, cast pipe fitting with female National Pipe Taper (NPT) threads for connecting and/or extending pipes going in the same direction. The design of the half coupling allows it to achieve a tight connection and reliable sealing through threaded connections.
The material used in stainless steel half coupling is generally 304 stainless steel or 316 stainless steel. They have a smooth and corrosion-resistant surface with good durability. It is a very commonly used pipe connection fitting and is widely used in pipeline systems, especially where threaded connections are involved.
They are commonly used in piping systems in the chemical, petroleum, food processing, pharmaceutical, and other industries to connect pipes, valves, equipment, or other accessories. Stainless steel half coupling can provide reliable sealing and connectivity and is suitable for the transmission of high pressure, high temperature, or special medium.
