Stainless Steel Flanges Manufacturer | ASTM A182 Blind/ SORF Flanges

What Is Stainless Steel Flange?

Stainless steel Flanges are components of ferrous groups, which are employed to connect pipes, valves, and other piping equipment. Stainless steel flanges have an 11% concentration of chromium, which helps in forming a protective layer. The layer inhibits corrosion and oxidation in different systems. The flanges in this range bolster superior strength and securely seal the entire system. These flanges can also be welded and maintained easily for long periods.

ASTM A182 Flanges Features

ASTM A182 flanges are forged martensitic stainless steel components. Some of the features of the A182 module includes:

Excellent corrosion resistance
Superior strength
Able to withstand high pressures and temperatures
Act as secure sealant
Easy access for inspection and cleaning
Can be welded or screwed
Modified without causing damage to the whole piping module
Long service life and stability

SS Blind Flanges Vs Stainless Steel Slip On Flange

Flanges are components, which are available in a range of sizes and shapes, and face types.

SS blind Flanges are designed without a hub or a face. These flanges are utilized to seal or block piping systems. The flanges are generally bolted, which allows easy access for cleaning and inspection. They possess excellent strength, as they have to resist high pressures in the system.
Stainless steel slip on flange is one of the preferred and economical flanges in the piping industry. Designed with a low profile head these flanges can be slid on the pipe and welded using one or two filet welds. They are preferred in low-pressure systems.

ASME SA 182 SS Weld Neck Flange Application

ASME SA 182 SS Weld Neck Flanges are some of the strongest flanges in the system. Their long protruding neck provides support to different components during rigorous movement and rising pressures across the system. They are generally seen in applications, where there are fluctuations in the temperatures and pressures. These flanges can be employed to handle volatile and hazardous fluids at sub-zero temperatures. Commonly seen in machinery industry, ring artifacts, welding dissimilar metal, oil and gas transportation, power generation, etc.

Difference Between Stainless Steel Threaded Flange And SS Lap Joint Flange

Stainless steel Threaded Flanges are components, which have threads that help them in connecting to the corresponding threads onto pipe or valves. They don’t require welding and are not preferred in high-pressure systems.
SS Lap joint flanges are two-part flanges consisting of a backing lap joint flange and a stub end. The stub end is slid onto the pipe and butt-welded in place. These flanges are suitable for high pressure and temperature systems.
