PDO Approved Buttweld Fittings Manufacturer In India, Check ASME B16.9 Pipe Fittings Dimensions Chart.
When it comes to pipe safety, ASME has just the correct definition. The industries and the government have been relying on ASME B16.9 Pipe Fittings since 1922 as they truly serve the purpose of their work.
This standard Buttweld Fittings Manufacturer In India offers sizes NPS ½ through NPS 48 (or DN 15 through DN 1200) from dimensions to tolerance, testings, etc. One of the highlights of this factory-Made Wrought Buttwelding Fittings is that they cover fittings on all types of walls, no matter their thickness. However, this one does not cover the corrosion-resistant buttweilding fittings. These Seamless Buttweld Fittings come with short radius elbows and return.
The dimension of the ASME B16.9 Seamless Welding Fittings are ANSI/ASME B16.9 Fittings, ASME B16.28, MSS-SP-43. These are available in size NPS ½ through NPS 48 (or DN 15 through DN 1200). We offer different fittings like Seamless, Welded, ERW, and Fabricated according to your requirements. Various schedules like 10S, S20, XS, S100, XXS, etc. are available, when it comes to thickness. Finally, this standard is available in different types of Elbow like 45 Deg Elbow, Long Radius Elbow, Short Radius Elbow, LR Elbow, SR Elbow, and Tee like Unequal Tee, Reducing Tee, Pipe Tee, Butt weld Unequal Tee, etc.
We are high-quality manufacturers of Schedule 40 Steel Pipe Fittings in India. According to the client's requirements, we have ANSI B16.9 BW Fittings available in all dimensions, shapes, and sizes.
