ASME B16.9 Welded fittings

The ASME B16.9 Standard covers tolerances,  welded fittings pressure rating, overall dimensions, testing, as well as markings for wrought grade butt-welded fittings manufactured in a factory. Welded fittings produced according to the ASME B16.9 standard are available across the world in the size ranging between NPS 1/2 through  NPS 48 Carbon Steel Weld fittings are about  20% lower  ASME working pressures in comparison to a seamless type of fitting, even though the material used to produce and the size of both kinds of constructed fittings are the same. This is because the welded fittings dimensions will have a seam, unlike the seamlessly constructed fittings, which have no seams.

Seamless buttweld fittings have no seam welds and are therefore considered superior to welded BW fittings (a weld is always a weak point on the metal, prone to corrosion). ASME B16.9 Welded fittings are manufactured by processing seamless pipes into desired forms. The processing of these fittings is done by cutting, heating, followed by shaping them. Typically a Welded fitting could either have one, two or more welds. The number of welds on these Stainless Steel Welded fittings would be dependent on the dimension, in addition to the kind of fitting to be produces as well as the manufacturing process that has been adopted by the mill.
