Stainless Steel 310 Flanges and ASTM A182 F310 Blind/ Weld Neck Flange

What is Stainless Steel 310 Flanges?

Stainless Steel 310 Flanges belong to the carbon austenitic grade. These flanges are utilized in high-temperature systems of up to 1150 degrees C. These flanges ensure a secure seal and resist corrosion and oxidation across different environments. Their high concentration of chromium and nickel allows these modules to work in carburizing and reducing sulfur atmospheres. The flanges in this grade are also preferred in cryogenic temperatures due it superior toughness and lower magnetic permeability.

DIN 1.4841 Forged Flanges Application

A DIN 1.4841 forged flange is utilized to link parts and components of machinery. These flanges have consistency in the composition as well as their structure. The flanges in this grade have several applications, which include utilization in cryogenic components, food processing, furnaces, burners, ore processing, petroleum refining, power generation, coal combustors, cement plants, thermal processing, and so on.

Comparision Between SS 310 Weld Neck Flange and A182 F310 Slip On Flange

Weld neck and slip on flanges are the most popular flanges utilized in the piping industry. These flanges can be differentiated based on some basic aspects.

A SS 310 Weld Neck Flange can be recognized by its long tapered and protruding head. An A182 F310 slip on flange has a low profile head.
Slip on flanges are slid on the pipe and welded using a fillet weld. Weld neck flanges are directly welded onto the piping component using a butt-weld.
The long neck of the weld neck flange provides support to other components through high pressures and temperatures. Slip on flanges are used in low-pressure and temperature applications.

SS Grade F310 Blind Flanges VS ASME SA182 SS 310 Pipe Flanges

SS 310 Blind Flanges are designed without a face or a bore. These flanges are utilized to seal piping ends or block them for new installation or repairs. The flanges in this grade are generally bolted and can be used for inspections and checks. The 310 blind flanges can withstand heavy pressures.
SS 310 Pipe Flanges are diversified and have over 13 types. These flanges possess a range of faces or bores, which can be welded or bolted. They can be utilized in high as well as low pressure or temperature systems.
