L/r 90° Elbow Carbon Steel Butt-welding Fittings

The butt welding pipe fittings could be seamless or welded in body.The seamless butt welding fitting means there is no welding seam on the body of the fitting when manufacturing,it is usually produced from the seamless steel pipes.The welded butt welding pipe fitting means there is a welding seam on the body of the fitting when manufacturing,usually,it is produced from the welded pipes or formed steel. plates.

A common example using welded pipe fitting is a pipe reduced by concentric reducer, welded to a weld neck flange and connected to an equipment. Figure below represent complete collection of butt welded pipe fitting

All butt weld fittings have beveled ends as per ASME B16.25 standard. This helps create full penetration weld without any extra preparation needed for the butt weld fitting.

Butt weld pipe fittings allow for changing the direction of flow, reducing pipe sizes and attaching auxiliary equipment.

Fittings applications and markets

Carbon steel pipe fittings production process

Manufacturing standards are governed under ANSI/ASME B 16.9. Butt-Weld Fittings are available in variety of kinds such as tees, caps, elbows, reducers and outlets.

ASME B16.9

This Standard covers overall dimensions, tolerances, ratings, testing, and markings for wrought factory-made buttwelding fittings in sizes NPS 1 ⁄ 2 through 48 (DN 15 through 1200).

A butt weld pipe fitting is made by the process of hot forming that includes bending and forming to shape. The starting material of butt weld fitting is a pipe that is cut to length, heated and molded into specific shapes by means of dyes. Heat treatment is also done to remove residual stresses and obtain desired mechanical properties.

Butt weld pipe fittings allow for changing the direction of flow, reducing pipe sizes and attaching auxiliary equipment.

A butt welding pipe fitting means the a pipe fitting which has the connecting end for butt welding.

The butt welding pipe fittings are used to connect with pipes or fittings with a same size and same schedule butt welding ends.The ends of the butt welding pipe fittings are plain ends or bevel ends.Commonly the butt welding pipe fittings includes elbows,tees,reducers,caps,paddles,stub ends,crosses,hot induction bends.

The benefit to using a butt weld fitting is that it doesn’t leak. Because the butt weld is welded directly to pipe and not simply bolted together, it is not only much stronger than a typical fitting, but it allows for better flow through the system with less resistance to friction. Welded fittings also allows for better layout designs through key features such as being more compact and greater in strength.
