Welded pipe fittings in carbon steel and stainless steel are the joining components that make possible the assembly of valves, pipes, and equipment onto the piping system. Welded fittings compliment pipe flanges in any piping system and allow:
All butt weld fittings have beveled ends as per ASME B16.25 standard. This helps create a full penetration weld without any extra preparation needed for the butt weld fitting.
Welded pipe fittings are made as per ASME spec B16.9. ASME B16.9 covers factory made wrought steel butwelding fittings in sizes 1/2″ to 48″. This standard however does not cover low pressure corrosion resistant buttwelding fittings. See MSS SP-43, Wrought Stainless Steel Butt-Welding Fittings.

Socket Weld Fittings are also called as high pressure fittings and used in various industries applications. These Socket Weld Fittings are attached to pipe with flanges and then assembled with stronger weld. Although Socket weld Pipe Fittings are widely used for small pipe whose nominal diameter is NPS4 or smaller.
