PIPE FITTINGS DIMENSIONS
(ASME B16.9 / ASME B16.11)


In this article, we show the ASME B16.9 (butt weld type) and ASME B16.11(forged type) pipe fittings dimension and weight charts by fitting shape (elbows, tees, caps, concentric and eccentric reducers).


 

BUTT WELD FITTINGS SIZES ASME B16.9

butt weld fittings

Butt weld elbows, tees, reducers and caps are a special type of pipe fittings that are welded with pipes to implement specific layouts for a pipeline. Butt weld fittings are used for bore sizes above 2 inches, whereas forged fittings are used for pipeworks below 2 inches. The ASME B16.9 charts reported below, show the butt weld pipe fittings dimensions and weights in kilograms – dived by shape.

FORGED FITTINGS DIMENSIONS ASME B16.11

Forged fittings are manufactured our of forged steel and used in pipelines and pipeworks below 2 inches (sometimes up to 4). Forged pipe fittings dimensions comply to ASME B16.11.

This type of fittings can be grouped into two major groups: threaded (the pipe is screwed into the fitting) and socket weld (pipe fittings welded onto the pipe). For more information about forged fittings, read this article.

Forged fittings dimension and weight

Dimensions and weights of forged fittings per ASME / ANSI B16.11 can be downloaded here.

If you are looking for Weldolet dimensions and weight (branch connections, under the forged pipe fittings family), refer to this article
