Vikalp Steel Industries is an ISO-certified and MSME-registered company specializing in the manufacturing of stainless steel stub ends. Below is a comprehensive overview of our product offerings:

Product Description: Stainless Steel Stub Ends

Stub ends are essential components in piping systems, serving as alternatives to welded flanges where rotating backup flanges are desired. They are predominantly used with standard lap joint flanges and are integral in facilitating the assembly and disassembly of pipelines without the need for cutting or welding. This design ensures ease of maintenance and flexibility in various industrial applications.

Manufacturing Types

We manufacture both long pattern and short pattern stub ends, adhering to the following standards:

  • ASME B16.9: Factory-Made Wrought Buttwelding Fittings
  • ASME B16.28: Wrought Steel Buttwelding Short Radius Elbows and Returns
  • MSS-SP-43: Wrought and Fabricated Butt-Welding Fittings for Low Pressure, Corrosion Resistant Applications

Size Range:

Our stainless steel stub ends are available in the following size ranges:

  • Outside Diameter: ½ inch to 24 inches
  • Wall Thickness: 2 mm to 100 mm, encompassing schedules SCH5, SCH10, SCH20, SCH40, SCH80, SCH120, SCH160, and XXS

Grade Range and Chemical Composition:

We offer stub ends in various stainless steel grades, each with specific chemical compositions:

  • 304/304L: Low carbon content for improved weldability.
  • 316/316L: Enhanced corrosion resistance due to added molybdenum.
  • 321: Stabilized with titanium for resistance to intergranular corrosion.
  • 347: Stabilized with niobium for enhanced corrosion resistance.
  • 904L: High alloy with excellent resistance to corrosion in aggressive environments.
  • 317L: Higher molybdenum content for increased corrosion resistance.
  • 310S: High chromium and nickel content for excellent oxidation resistance at elevated temperatures.

Connection End Types:

Our stub ends are designed with the following connection end types:

  • Type A: Suitable for standard lap joint flanges, with a machined serrated face and specific corner radii.
  • Type B: Compatible with slip-on flanges acting as lap joint flanges, featuring a machined serrated face and distinct corner radii.
  • Type C: Versatile for use with both lap joint and slip-on flanges, offering a smooth surface and adaptable corner radii.
