Buttweld

Buttweld

Buttweld fittings are pipe fittings used to connect sections of pipe by welding them together, offering a strong, leak-proof, and permanent joint. They are commonly used in high-pressure and high-temperature piping systems across industries such as oil & gas, power plants, petrochemicals, and shipbuilding. Buttweld fittings come in various types including elbows, tees, reducers, and caps, which allow for directional changes, branching, and diameter transitions in the piping layout. These fittings are manufactured to ASME B16.9 and B16.28 standards and are available in materials like carbon steel, stainless steel, and alloy steel for compatibility with a wide range of applications.
