ASTM A182 Stainless Steel F316 Weld Neck Flanges

Flanges are an essential component in piping systems. They help connect pipes, valves, and fittings, allowing for a seamless fluid and gas flow. Stainless steel flanges are highly preferred in various industrial applications because of their high strength, corrosion resistance, and durability. ASTM A182 Stainless Steel F316 Weld Neck Flanges are one of the most popular types in the market. ASTM A182 Stainless Steel F316 weld neck flanges are available in different types to cater to various industrial applications. These types include standard, long, and extra-long. Standard weld neck flanges are the most commonly used and have an average neck length. Long weld neck flanges are used in high-pressure systems where there is a need for increased strength and support. Extra-long weld neck flanges have an extended neck length and are highly preferred in high-pressure piping systems.

ASTM A182 Stainless Steel F316 weld neck flanges are essential to any piping system. They offer numerous benefits, including high strength, durability, resistance to corrosion, and ease of installation and maintenance. When choosing a stainless steel F316 weld neck flange, consider its type and ensure it is suitable for the specific application.


An ASTM A182 SS F316 weld neck flange is a type of flange that is made from stainless steel grade F316. It is a welding-type flange that is cast or forged integrally with the tapered neck. It is then buttwelded to the piping system. The ASTM A182 SS F316 weld neck flange is made of austenitic steel consisting of 18% chromium & 8% nickel and it is this composition that makes the flange strong & highly resistive to corrosion.

ASTM A182 SS F316 Weld Neck Flanges offer excellent corrosion resistance, high strength, and durability. They have a raised face & a tapered hub, facilitating smooth flow and reducing turbulence in piping systems.

ASTM A182 SS F316 Weld Neck Flanges are available in a range of sizes, typically ranging from 1/2 inch to 24 inches or even larger. The specific size availability may vary depending on the manufacturer & supplier.
