Fittings are important instruments that help join different piping systems together. Buttweld 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 Cap 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.

REDUCERS: Outer Die method
One of the most common method for manufacturing Reducers, using an outer die. Raw material pipe is cut and pressed in an outer die, compressing one end of pipe into a smaller size.
REDUCERS: Plate Forming method
Plates can also be used to manufacture Reducers. In an UO method, plate is cut in a specially designed shape which is formed into an U-shape and an O-shape respectively, then finished with a single weld seam. The “Monaka” method for Tees is similar to that of Elbows, using two symmetrically cut plates formed and welded together with two seams. Both methods are used for large diameter items.
CAPS: Deep Drawing method
One of the most common manufacturing methods for caps, where plate is cut out in a circle and formed by deep drawing.
LAP JOINTS / STUB ENDS: Flare method
One of the most common manufacturing methods of Lap Joints / Stub Ends. One end of the raw material pipe is spread out to form the brim. There are other methods, where the brim is welded onto the end of a cut pipe or where the whole product is machined from block.
