Leading Manufacturer of Stainless Steel 347 BW 90 degree, 180 degree Elbow, Long & Short Stub End, DIN 1.4550 Lap Joint Stub End, EN X6CrNiNb18-10 Piggable Bend, JIS SUS347 U Bend, GOST 08Х18Н12Б Hot Induction Bend, BS 347S31 pipe fittings, AFNOR Z6CNNb18-10 Elbow (1D, 1.5D, 3D, 5D, 10D) Fittings

Stainless steel 347 pipe fittings are available in sizes from 1/2" NB to 48" NB and come in seamless and welded types. They adhere to ASME/ANSI B16.9, ASME B16.28, MSS-SP-43, BS1560, BS4504, and BS10 standards. These fittings, including elbows, tees, U pipe bends, and stub ends, offer thickness options from Schedule 5S to XXS. Manufactured to ASTM A403 / ASME SA403 WP347 specifications, they provide excellent resistance to intergranular corrosion and high-temperature stability, making them ideal for demanding industrial applications.

In 347 stainless steel buttweld fittings, seamless and welded options play crucial roles in meeting diverse industrial needs. Seamless fittings offer superior strength and corrosion resistance due to their lack of welds, making them ideal for high-pressure and high-temperature applications. Welded fittings, on the other hand, are typically more cost-effective and easier to manufacture in larger sizes, making them suitable for lower pressure applications. Both types ensure reliability and performance, adhering to stringent industry standards and specifications.

Producing SS 347 fittings involves selecting high-quality 347 stainless steel and forming it through hot forging or cold forming techniques. The fittings are then precisely machined to achieve accurate dimensions and smooth surfaces. Welding may be performed for specific types, followed by heat treatment processes like annealing to relieve stresses and enhance mechanical properties. Rigorous inspections and testing ensure compliance with industry standards, ensuring the fittings meet required specifications for performance and reliability in various applications.
