Merchant coupling

Merchant couplings are specialized fittings used to join pipes in a straight-line run, primarily in low-pressure piping applications like water, oil, air, and gas lines. THey are typically made from steel tubing and be available in various materials, including carbon, galvanized, and stainless-steel. Merchant couplings are designed for use in situations with pressures of 150 psi or less and are not suitable for high-pressure environments.

These couplings are available in different styles, including full and half merchant couplings. Full merchant couplings are used for stronger connections, while half merchant couplings provide a threaded outlet for welding onto flat surfaces, including tanks. Merchant couplings can have either straight or tapered threads, with tapered threads providing a better seal because of their design.

Overall, merchant couplings are essential for creating long, continuous runs of pipe while ensuring a secure connection, making them a vital component in various industrial and construction applications.
