Fittings
At Metrade, we specialize in providing top-quality Buttweld fittings that are engineered for durability, precision, and performance. Designed for applications where long-term reliability and pressure resistance are critical, our Buttweld fittings are the go-to choice for a wide variety of industrial systems. They offer seamless, high-strength connections that minimize the risk of leakage and maximize the integrity of your piping network.
Buttweld fittings are a type of pipe fitting used to connect pipes, valves, or equipment by welding the fitting directly to the pipe. These fittings are commonly used in systems that require strong, permanent, and leak-proof connections. The term “buttweld” refers to the process where the ends of the pipes or fittings are butted together and then welded along the joint to create a secure connection.
