Buttweld Fittings

ASME B16.9 Pipe End Caps and Butt Weld Elbow manufacturer in India

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. We are the leading Buttweld Fittings manufacturer in India. We thrive to manufacture top-quality products, which are available at feasible prices.

Buttweld Fittings

Butt Weld Tee is a pipe fitting that has 3 openings. Each opening can connect pipes together. This is used to increase the flow of fluids and gases or divert the flow in different piping systems. This Tee Butt Weld helps in connecting the fitting to a stud or the divider. They are widely used in the transportation of potable water and firefighting systems. These tees are available either as equal or reducing tees. The Butt Weld Reducing Tee has an opening that is smaller in comparison to the other two openings. 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. We are the Pipe Fittings manufacturers in India who can customize all our products in different shapes and sizes as per the requirements of our clients.

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. If you have any queries or want to know more about our products, contact us for more information.

Manufacturing Buttweld Fittings

The most appropriate manufacturing method of a product will be decided with consideration of its material, sizes, shape, use, standards and other properties.

There are numerous processes for manufacturing Elbows alone, several examples listed as follows.

ELBOWS: Mandrel method (Hot Forming)

One of the most common manufacturing methods for manufacturing Elbows from pipes. After heating the raw material, it is pushed over a die called "mandrel" which allows the pipe to expand and bend simultaneously. Applicable to a wide size range.

Manufacturing Butt Welding ELBOWS

ELBOWS: Extrusion method (Cold Forming)

Using raw material with the same diameter as finished product, pipe is pushed through a die and formed into its desired shape. Usually applied to stainless steel, small to medium sizes.

Manufacturing chart-ELBOWS: Extrusion method (Cold Forming)

ELBOWS: UO method

After raw material plate is cut out into a specially designed shape, it is shaped first into an U-shape using a die and then into an O-shape (tubular form) using another die, finished with a single weld. Usually applied to stainless steel and non-steel material, small to medium sizes.

Manufacturing chart-ELBOWS: UO method

ELBOWS: "Monaka" method

One of the most common method for manufacturing Elbows from plates. After two pieces of raw material plates are cut out symmetrically, each piece are press formed and welded together, which somewhat reminds us of the Japanese delicacy, "Monaka." This method is applicable to various materials and can even be applied to large items with diameters over 1 meter. Has two seams and special welding technology is in use to meet various standards required by our clients (electricity, gas pressure vessels, etc.,) from whom Steel Tubes products continue to receive high acclaim.

ELBOWS: Hot Forming Die Bending method

After heating raw material pipe, it is press formed and corrected using different dies. The process may be repeated as needed to obtain the required shape, size, wall thickness, etc. Usually applied to thick-wall items that cannot be bent on a mandrel die.

TEES: Hydraulic Bulge method (Cold Forming)

After cutting and placing raw material into a die, the pipe is pressed as hydraulic pressure pushes out the branch. The Tee is pressed against the die, leaving the finished product to have a truly smooth outer surface.

Manufacturing chart-ELBOWS: "Monaka" method

TEES: Extrusion method (Hot Forming)

Using raw material with a bigger diameter than the finished product, the branch outlet is extruded from pipe while the main body is being pressed. The outlet's wall thickness can also be adjusted as needed. Applied to Tees with large diameters, heavy wall thickness and/or special material with challenging workability that cannot be manufactured using the hydraulic bulge method.

TEES: Steel Plate Welding method

Manufacturing methods for Elbows, using steel plates as the raw material. Includes UO-method, Monaka method and Throat-welding method.

UO method: After raw material plate is cut out into a specially designed shape, it is shaped first into an U-shape using a die, then the branch pipe is formed and then shaped into an O-shape (tubular form) using another die, finished with a single weld on the opposite side of the branch pipe. Usually applied to large diameter items used in severe conditions.
"Monaka" method: Two pieces of raw material plates cut out symmetrically are press formed and welded together. Usually applied to large-diameter items.
Throat-welding method: Mainly used for stainless and non-metal items, this method is similar to UO-method but with the weld on the same side as the branch pipe and the "branch throat." Usually applied to low-pressure, corrosion-resistant items.

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.

Manufacturing chart - REDUCERS: Outer Die method

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.
