    Description

    Fittings are important instruments that help join different piping systems together. Butt weld Fittings provide a unique way to join piping systems together. In this, fitting pieces of metal are placed over each other and welded. These fittings are unique because of the superior strength and excellent tolerances they exhibit in stress-induced environments. The Butt Weld Pipe Fittings provides options for manipulating the piping system in various directions or pressures. These fittings provide a leakproof and reliable piping connection. The Butt Weld Elbow is used to change the direction of flow of both fluids and gases in these systems. These elbows come in either short or long radius elbows. Their direction can be changed by 22.5, 45, 90, and 180 degrees. The Butt Weld 90 Elbow is known as a quarter bend elbow and is the most common elbow in the industry. These elbows possess superior tensile and yield strength. They allow for a smooth movement of flow through them. Reducing Elbow Buttweld are made up of openings of different sizes. This enables them to connect pipes of different sizes in a piping system.

    These tees are common components in vacuum cleaners. In the Butt Weld Reducer, different sizes of pipes can be installed. These reducers are also used in systems wherein the pressure is increased or decreased significantly. They are available as either concentric or eccentric reducers. 

    The Butt Weld Pipe Cap is used as a protective device on pipes, which protects them during transportation from falls. It also acts as a device to prevent the pipes from getting corroded due to moisture build-up. Butt Weld stub ending can also help eliminate air blocks in pipelines. They are available in lengths up to 700mm. Our experience makes use of the latest technology and top-quality raw materials while producing all the products of the ASME B16.9 Buttwelded Fittings.
