A pipe flange is a disc, collar or ring that attaches to pipe with the purpose of providing increased support for strength, blocking off a pipeline or implementing the attachment of more items. They are usually welded or screwed to the pipe end and are connected with bolts.

A weld neck flange (also known as a high-hub flange and tapered hub flange) is a type of flange. There are two designs. The regular type is used with pipes. The long type is unsuitable for pipes and is used in process plant.. 


  • Materials - ASTM A105M
  • Dimensions - ASME B16.5


  • Oil, Gas, Petrochemical.


  • All Flanges when possible will display a heat number, size, table, grade and dimensional standard.

    Forged Steel Flanges

    • Forged Steel flanges are commonly used and specified in the Oil, Gas, Petrochemical and mining sectors, where pressure, temperature and safety considerations often specify the ANSI B16.5, ASME B16.47 or BS4504 standards.
    • The manufacturing method involves the hot forging of suitable steels prior to final machining.
