SS 316L flange is a type of stainless steel flange made from Grade 316L, which is a low-carbon version of 316 stainless steel. This material is well known for its excellent corrosion resistance, especially in harsh environments involving chemicals, saltwater, or high humidity. The low carbon content in 316L makes it ideal for welding applications, as it minimizes the risk of carbide precipitation and ensures better resistance to intergranular corrosion.

These flanges are commonly used to connect pipes, valves, pumps, and other equipment in a piping system. They are strong, durable, and can handle both high pressure and high temperature, making them suitable for a variety of industries including oil and gas, chemical processing, food and beverage, pharmaceuticals, and water treatment. Different types such as weld neck, slip-on, blind, socket weld, threaded, and lap joint flanges are available, depending on the specific needs of the system. Overall, SS 316L flanges are a reliable and long-lasting solution for applications that demand high corrosion resistance and mechanical strength.

ASTM A182 F316/316L – 2" Dummy Flange

This refers to a dummy flange (also known as a blank flange or blind flange) manufactured from Stainless Steel ASTM A182 Grade F316/316L, with a nominal bore size of 2 inches (50 NB). It is used to close the end of a piping line or nozzle opening, providing a secure seal for testing, maintenance, or temporary shutdown of a section of the pipeline.

Detailed Description:
The ASTM A182 F316/316L dummy flange is made from forged stainless steel containing molybdenum for enhanced corrosion resistance, especially against chlorides and acidic environments. The “L” variant (316L) offers lower carbon content, minimizing carbide precipitation during welding and improving resistance to intergranular corrosion.

Specifications:

• Material: Stainless Steel

• Grade: ASTM A182 F316 / F316L (Dual Grade)

• Type: Dummy Flange / Blind Flange

• Size: 2 Inch (50 NB)

• Standard: ASME B16.5

• Pressure Class: Commonly available in Class 150 / 300 / 600 (as per requirement)

• Facing: Raised Face (RF) / Flat Face (FF) as specified

• Finish: Machined Face with Smooth Surface Finish

• Manufacturing Type: Forged, CNC Machined

• Application: Used to terminate or isolate sections of stainless steel piping systems in chemical, petrochemical, marine, and process industries.

ASTM A182 SS 316 BSP Thread Flange 2" manufactured by Raj Metals, Mumbai is a high-quality stainless steel threaded flange designed for superior corrosion resistance and mechanical strength. Produced from Stainless Steel Grade 316, this material contains approximately 16–18% Chromium, 10–14% Nickel, and 2–3% Molybdenum, which together enhance its resistance to chlorides, acids, and high-temperature oxidation. The presence of molybdenum makes it far more durable than SS 304, especially in marine, chemical, and industrial environments.

The BSP (British Standard Pipe) threaded flange is manufactured as per ASME B16.5 and BS 4504 standards, ensuring perfect dimensional accuracy and thread compatibility. The thread type follows ISO 7/1 – BSPT (British Standard Pipe Taper) or BSPP (British Standard Pipe Parallel) as per customer requirement. The nominal size of 2 inches (50 NB) allows it to fit standard 2" BSP threaded pipe connections without welding, providing easy installation and maintenance access.

Each SS 316 BSP Thread Flange is forged and machined from ASTM A182 F316 stainless steel, ensuring a fine-grain structure, excellent tensile properties, and leak-proof sealing. The material offers a tensile strength of around 515 MPa, yield strength of 205 MPa, and elongation of 40%, providing excellent ductility and mechanical reliability under pressure and vibration.

These flanges are generally available in pressure classes from 150# to 600#, and can be supplied in Raised Face (RF) or Flat Face (FF) designs depending on the piping system requirement. The standard surface finish on the sealing face is Ra 3.2–6.3 µm spiral serrated finish, ensuring proper gasket grip and tight sealing under pressure.

Applications include chemical plants, petrochemical refineries, food processing units, water treatment systems, marine fittings, and gas distribution lines, where corrosion resistance and hygiene are vital.

At Raj Metals, Mumbai (+91 81045 97964), every flange undergoes PMI testing, dimensional inspection, and visual surface examination to ensure conformance to ASTM, ASME, and ISO standards. We supply SS 316 BSP Threaded Flanges in both machined and mirror-polished finish, with full traceability and material test certification (MTC) provided upon request.
