Stainless Steel Socket Weld Flange Manufacturer and A182 SWRF Flange

What is Stainless Steel Socket Weld Flange?

Socket weld flanges are compact structures that have a socket wherein a pipe is inserted. The pipes within the socket are secured using one fillet weld. The ferrous coating on these flanges gives them superior corrosion resistance properties. These flanges are designed for high-pressure pipes of small sizes. The flanges are available as raised or flat-faced and used as per the requirements of the application.

ASME B16.5 Socket Weld Flange Uses

Socket weld flanges are generally used for high-pressure pipes of smaller sizes. These flanges are a preferred choice in systems where internal welding operations are difficult. They are widely seen in stainless steel superheaters as they avoid cracking defects caused by thermal stresses. These modules act as standard applications for a major type of material.

ASTM A182 F304 Socket Weld Flange vs ASTM A182 F316 Socket Weld Flange

304 and 316 grades of ASTM A182 socket weld flanges are amongst the popular grades of flanges used in this range across piping systems. These flanges can be readily distinguished based on their respective chemical compositions.

A 316-grade socket weld flange possesses a chemical composition of 16% chromium, 10% nickel, and 2% molybdenum. A 304-grade socket weld flange has a chemical composition of 18% chromium with 8% nickel.
The 304-grade has superior corrosion resistance properties but is not safe from chloride pitting. In the 316-grade, the 2% of molybdenum allows it to be resistant to pitting by chlorides.
304-grade is cheaper than the standard 316-grade of socket weld flanges.

Differnce Between ANSI B 16.5 Class 600 Socket Weld Flange and class 2500 Socket Weld flange

Class 600 and 2500 are pressure classes of socket weld flanges. A pressure class is defined as the maximum pressure allowed that a flange could withstand as the temperature increases. ANSI B16.5 class 600 flange is designed to withstand pressures up to 890 psi of pressure at 600 degrees F. A class 2500 socket weld flange is bigger in comparison to a grade 600 flange. These flanges can withstand pressures of 4730 psi at 600 degrees F.

SS Socket Weld Flange Features

Some of the features of a socket weld flange include:

A socket or recessed area is utilized to fit the pipe
Well suited for small pipes, for higher pressures
Available in raised or flat face
No requirement of pre-weld bevelling
Corrosion resistance properties due to ferrous coating
Welding using a single fillet weld
