Manufactured by us in ASTM A403 WP309, ASME B16.9, ANSI B16.9, ASME B16.28, ANSI B16.28, ANSI B16.25, MSS-SP-43, and MSS SP-75 INTERNATIONAL standards, our 309 pipe fittings can well define the epitome of preciseness and quality. This huge range consists of butt welding fittings like Elbows-long and short Radius; Tees-Equivalent and Reducing; Crosses; Caps; Reducers; Collars; and many other variations in configurations. The Stainless Steel 309 elbow is a very important fittings installed between the two pipes to enable directional changes of 180°, 90°, or 45°. When the ends of the pipes in question differ in size, they get processed into butt welding fittings so they are termed as reducing pipes or reducing elbows.
We provide pipe fitting elbows that can be bent up to 180°, 90°, or 45°, and with numerous radius options including 1D, 1.5D, 2D, 3D, 5D, 6D, 8D, and 10D, comprising short and long radius variations. Each of our ASTM A403 elbows is carefully shaped with a mandrel, thereby ensuring uniformity and reliability of shape in every piece.
At Sankalp Alloys Overseas, the meaning goes beyond just products; it symbolizes excellence in consumerism. We work our best to assure that every client gets fittings that are tailor-made according to their criteria and specifications. By virtue of better corrosion resistance and high-temperature properties, Stainless Steel 309 Pipe Fittings find continuing applications in a very wide spectrum of industries, including petrochemical, oil and gas, power generation, and other general industries.
