Half Coupling is also called Half Socket which is a Pipe Fitting for extending and connecting pipes. Female NPT threads for connecting to the male pipe. The half coupling has threads for creating tighter seals than straight threads.
Stainless steel 304, and 316 stand out for their enhanced durability and resistance to corrosive elements, making them a reliable choice for demanding applications.
Type 304 stainless steel is a chromium-nickel material that resists corrosion caused by water, heat, salt water, acids, minerals, and peat soil. Type 316 stainless steel has a higher nickel content than 304 stainless steel, which, combined with molybdenum, provides greater corrosion resistance.
To ensure the quality and compatibility of different systems.150# stainless steel half couplings are ideal for general use and reduce the risk of operational disruption due to part failure or incompatibility. Use Class 3000 fittings in high-pressure applications, and use PTFE tape to secure the seal.
Stainless steel threaded half coupling suitable for a variety of applications in harsh environments. Like electric power, chemical engineering, shipbuilding, nuclear energy, garbage disposal, natural gas; petroleum oil etc.
