Weld neck pipe flanges
attach to the pipe by welding the pipe to the neck of the pipe flange.  This allows for the transfer of stress from the weld neck pipe flanges to the pipe itself.  This also reduces high stress concentration at the base of the hub of the weld neck pipe flanges.  Weld neck pipe flanges are often used for high pressure applications.  The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe.  Weld Neck Pipe flanges with a hub have published specifications that range from 1/2" thru 96". We provide Weld Neck pipe flanges in all material grades, specifications and sizes.

Weld neck pipe flanges are typically provided with a raised face, flat face, or RTJ facing.  When a raised face is necessary for weld neck pipe flanges, the standard height is 1/16" for weld neck pipe flanges fewer than 400#.  For weld neck pipe flanges of 400# and up, the standard weld neck pipe flange raised face height is 1/4". 

We manufactures weld neck pipe flanges in all steel material grades, including carbon weld neck pipe flanges, stainless steel weld neck pipe flanges and alloy weld neck pipe flanges. This Flange also has many different weld neck pipe flanges in stock and ready to ship.  Weld neck pipe flanges in stock include ANSI B16.5 weld neck pipe flanges, ASME B16.47 Series "A" weld neck pipe flanges; ASME B16.47 Series "B" weld neck pipe flanges, Pressure Vessel weld neck pipe flanges.  We also manufacture custom weld neck pipe flanges per customer requirements.

There are many different flange standards to be found worldwide. To allow easy functionality and inter-changeability, these are designed to have standardised dimensions. Common world standards include

  • ASA Flange /ANSI flanges /ASME flanges (USA),
  • PN flanges /DIN flanges (European),
  • BS10 flanges (British/Australian), and
  • JIS flanges /KS flanges (Japanese/Korean)

       In most cases these are not interchangeable (e.g. an ANSI/ASME flange will not mate against a JIS flange). Further, many of the flanges in each standard are divided into "pressure classes", allowing flanges to be capable of taking different pressure ratings. Again these are not generally interchangeable (e.g. an ANSI/ASME 150 will not mate with an ANSI/ASME 300).
These pressure classes also have differing pressure and temperature ratings for different materials. Unique pressure classes for piping can also be developed for a process plant or power generating station; these may be specific to the corporation, engineering procurement and construction (EPC) contractor, or the process plant owner. The ANSI/ASME pressure classes for Flat-Face flanges are 125# and 250#. The classes for Ring-Joint, Tongue & Groove, and Raised-Face flanges are 150#, 300#, 600#, 900#, 1500#, and 2500#.
The flange faces are also made to standardized dimensions and are typically "flat face", "raised face", "tongue and groove", or "ring joint" styles, although other obscure styles are possible.
Flange designs are available as "weld neck", "slip-on", "lap joint", "socket weld", "threaded", and also "blind".
Other countries
Flanges in other countries also are manufactured according to the standards for materials, pressure ratings, etc. Such standards include DIN, BS, and/or ISO standards.
