China Threaded Coupling Factory Custom Pipe Fittings Stainless Steel Extra Heavy Half Merchant Coupling Manufactured Per ASTM A865 ASME B1.20.1.
Made of 304 stainless steel, corrosion-resistant ductility at high temperatures, and low magnetic permeability;
Female x Female thread; Connection: NPT-NPT;
Female National Pipe Taper (NPT) threads for connecting male threaded pipes;
Pipe threads are used widely for pipes and are easy to replace and install;
It is a good choice for laying pipes in home buildings, and it is not easy to damage after long-term use.
There are so many different types of couplings available and each one has its specific application. For example, when connecting drop pipes in a well, you may consider using merchant couplings to connect them.
Extra-heavy half-merchant couplings are manufactured by ASTM A865. This type of coupling is furnished for the extra strong and double extra strong pipe. All are taper-tapped.
The stainless steel coupling has anti-corrosion, high strength, good sealing, aesthetics, and many other advantages. Safe stainless steel material lets pipe coupling be used in multiple applications, even those with high standards and strict demand applications.
Merchant coupling is a familiar fitting in pipelines. It is economical, durable, and a cost-effective pipe fitting. Merchant coupling is available in various materials to meet the needs of different applications, such as carbon steel and stainless steel, and a simple design to connect pipelines. Standard and extra heavy coupling are two typical types of coupling, female thread according to NPT and BSP thread.
