Stainless Steel Flanges: Types, Specifications, Weight Chart, HSN Code, Uses & Applications

  Stainless steel flanges are essential piping components designed to connect pipes, valves, pumps and other equipment through a secure bolted joint. Their corrosion resistance, mechanical strength and availability in different configurations make them suitable for demanding industrial environments. Depending on the piping requirement, options include Weld Neck, Slip-On, Blind, Socket Weld, Threaded, Lap Joint, Long Weld Neck, Spectacle Blind and Ring Type Joint designs. A suitable Stainless Steel flange Manufacturer can provide these products according to required dimensions, pressure ratings, material grades and applicable standards. What Are Stainless Steel Flanges? A flange is a rimmed or flat component used to create a detachable connection between piping components. Unlike permanent welded joints, a flanged connection can be dismantled for inspection, cleaning or maintenance. Stainless steel construction is particularly useful where corrosion resistance and long service life...

Benefits: Easy installation, cost-effective, and widely available.

C. Blind Flange

Description: A solid flange without a bore, used to close pipe ends.
Uses: Pipelines requiring inspection, maintenance, or testing.
Benefits: Provides a strong seal and prevents fluid flow when needed.

D. Threaded Flange

Description: Has internal threads to match externally threaded pipes.
Uses: Low-pressure applications where welding is not possible.
Benefits: Quick installation and removal without welding.

E. Socket Weld Flange

Description: Features a recessed socket to hold the pipe before welding.
Uses: High-pressure and small-diameter piping systems.
Benefits: Strong and reliable connection with excellent fatigue resistance.

F. Lap Joint Flange

Description: Works with a stub end for easy disassembly.
Uses: Systems requiring frequent dismantling, such as in chemical processing.
Benefits: Cost-effective and ideal for non-permanent connections.

2. Uses of Stainless Steel Flanges

Industries worldwide depend on stainless steel flanges due to their versatility and durability. Some common applications include:

  • Oil & Gas Industry – Used in pipelines for drilling, refining, and distribution.
