Stainless Steel Forged Fittings Specification

How does stainless steel forged fittings compare to cast fittings in terms of strength and durability?

Stainless forged fittings have superior strength and durability compared to cast fitting. This is because the stainless steel forged fittings manufacturer in India uses the forging production process. They also have higher durability and can resist mechanical stress better. They also have better impact resistance due to their dense and more uniform structure.


Stainless Steel Forged Fittings

What are the different pressure ratings and classes available for SS forged fittings?

The different pressure ratings and classes available for SS forged fittings range between class 2000-9000. There are also SS forged fitting available with 6M and 9M pressure ratings. They are mostly recommended for high pressure performance like in subsea oil & gas.

How do you identify the quality and authenticity of stainless steel socket weld fittings?

Incorporating proper quality control measures for stainless socket weld fittings can ensure they are reliable and authentic. You can conduct different types of tests like material tests to confirm the chemical composition and mechanical properties of the fitting. Visual inspection can help determine surface defects whereas NDT is designed for finding out sub surface irregularities. You can also conduct dimensional tests to ensure the SS socket weld elbows are within recommended dimensions. Clients can ask for several other tests on the SS forged pipe fitting as per their application requirements.

Can SS socket weld fittings be used in both above-ground and underground installations?

The SS socket weld fittings can be used for above-ground applications as the material has natural corrosion resistance properties. However, underground applications mean exposure to more corrosive conditions. To tackle this, the fitting can be coated with an extra layer of protection.

What are the industry standards that govern the manufacturing and use of stainless steel forged pipe fittings?

There are various industry standards for stainless steel forged pipe fittings like ASME B16.11, B31 series, ASTM A182, etc.


Stainless Steel Socket Weld Fittings are a family of high pressure fittings used in connecting and creating pipe-work systems whereby they are welded into the system using circumferential socket welds. These SS Socket Weld Fitting mainly used only in conjunction with ANSI Pipe and are available in the same size range. SS Socket Weld Elbow, SS Socket Weld Tee & SS Socket Weld cap are used in areas where pipe-work is permanent and are designed to provide good flow characteristics. We are manufacturer, supplier & stock holder of Stainless Steel Socket Weld Fittings in four pressure ratings: 2000lb, 3000lb, 6000lb & 9000lb. The same range of Stainless Steel high pressure fitting is also available with screwed ends with NPT threads.
