ASME B16.47 Industrial Flanges Manufacturers and Suppliers:
MSS-SP 43 and ASME B16.9 Buttweld Fittings are used for a piping system where the diameter is above 2 inches and for smaller size pipes forged threaded and socket weld fittings are used.
Buttweld Elbows are used to change the direction of pipelines with 45deg, 90deg, and 180deg being the most used elbows. to branch pipe, Tees and cross are used to increase or reduce the pipe bore size reducers do the work perfectly and to blind the pipeline butt weld caps are used.

ADCO Forge and Fittings is dominating player in the market of manufacturing and exporting large inventory of Buttweld Pipe Fittings ASME B16.9 in India (Asia), Middle East, and African Counties. Having complete solutions of pipe fittings that covers size ranging from NPS ½ through NPS 48 (DN 15 through DN 1200) for the industries like Chemical, Fabrication, Food Processing, Oil and Gas, Power, Petroleum, Shipbuilding, Etc.
Alloy steel and carbon steel pipe fittings dimensions and tolerances are covered under ASME/ANSI B16.9 specification. The MSS-SP 43 specification integrates ASME B16.9 to cover nickel alloys and stainless steel buttweld fittings. These pipe fittings are specified by nominal pipe size and pipe schedule. welded or seamless pipes are used to produce buttweld fittings such as tees, elbows, reducers, caps, reducers, and olets.
Stainless Steel welded butt weld fittings are more common due to their cost advantages. Similarly, as steel pipe, buttweld pipe fittings are sold from Schedule 10 to Schedule 160 and Sch 10 is the most common stainless steel buttweld pipe fittings.
We have the ready inventory of Industrial Flanges in the different size ranges of 1 Inch, 2 Inch, 3 Inch, 4 Iinch, 5 Inch, 6 Inch, 7 Inch, 8 Inch, 9 Inch Pipe Flanges.
