What is Stainless Steel Flanges?
Stainless steel flanges belong to a ferrous group of alloys. Designed with a minimum of 11% chromium content, the flanges show enhanced corrosion and oxidation resistance properties. The flanges of stainless steel are used to connect a range of piping equipment in place. The versatile flanges are well suited in high-temperature applications giving them excellent strength and torsion. A SS flange type can be threaded or welded following standard procedures.

What are Stainless Steel Pipe Flange used for?
Stainless steel pipe flanges are designed in a range of sizes and dimensions to suit different applications. SS flanges are a common feature in oil and gas industries, chemical processing, petrochemical refineries, pulp and paper productions, and so on.

Stainless Steel Lap Joint Flange Vs Ss Slip On Flange
Lap joint and slip on flanges are versatile grades in the C276 alloy grade. Both these flanges can be distinguished from key features.

A Stainless steel Lap Joint flange consists of a backing flange and a stub end which are welded in place using a butt-weld. SS Slip on the flange is slid on a piping grade and welded using one or more fillet welds.
Lap joint flanges are utilized in high-pressure applications. Slip on flange is a item of choice in low pressure applications.

How do you measure Stainless Steel Weld Neck Flange?
Stainless steel weld neck flanges are measured based on the inside and outer diameter of the flange. The flange class and thickness are employed in tuning the flange to suit different needs. The hole size and pitch circle diameter also play a crucial role in determining the dimensions of these flanges.

What Grade Of Stainless Steel Plate Flange Will Not Rust?
All grades of stainless steel are designed possessing superior corrosion resistance properties. When exposed to a range of oxidants and reducing agents for a period of time, they will eventually rust after providing a long service life across stress-induced environments.
