Stainless steel flanges are essential components in piping systems used across various industries, including oil and gas, chemical processing, power generation, food processing, and construction. They are utilized to connect pipes, valves, pumps, and other equipment to ensure smooth and secure operation. Understanding stainless steel flange sizes and grades is crucial for selecting the right product that meets the requirements of your specific project. In this guide, we will explore the different aspects of stainless steel flanges, their sizes, grades, and importance, as well as insights about reliable Stainless Steel Flange Manufacturers in India like Riddhi Siddhi Metal Impex.
What are Stainless Steel Flanges?
Stainless steel flanges are mechanical fittings that join pipes and equipment in a piping system. These flanges allow for easy disassembly and maintenance of the system, as well as facilitate proper sealing. They come in a variety of types, including:
Weld Neck Flanges: Used in high-pressure systems due to their strength and durability.
Slip-On Flanges: Easy to install and cost-effective, suitable for low-pressure systems.
Socket Weld Flanges: Ideal for smaller pipes and high-pressure applications.
Blind Flanges: Used to close the ends of piping systems.
Lap Joint Flanges: Often used with stub ends for systems requiring frequent dismantling.
Each type of flange serves a specific purpose and provides different levels of strength, durability, and sealing.
Stainless Steel Flange Sizes
Flanges are available in a wide range of sizes to meet the needs of different piping systems. The size of a flange is determined by factors such as pipe diameter, pressure ratings, and application requirements. Common standards for flange sizes include ANSI/ASME, DIN, BS, and EN.
The most widely used dimensions are classified under the following:
Nominal Pipe Size (NPS): Represents the approximate inner diameter of the pipe.
Pressure Rating: Ranges from 150 PSI (Class 150) to 2500 PSI (Class 2500), depending on the system's pressure requirements.
Flange Dimensions: Includes outer diameter (OD), bolt circle diameter (BCD), thickness, and bolt hole size.
For example:
Class 150 flanges for a 2-inch pipe may have a thickness of 19.1 mm and a bolt circle diameter of 120.7 mm.
Class 600 flanges for a 4-inch pipe may have a thickness of 57.2 mm and a bolt circle diameter of 190.5 mm.
Manufacturers like Riddhi Siddhi Metal Impex, one of the leading Stainless Steel Flange Manufacturers in India, produce flanges in a variety of sizes and specifications to meet customer requirements.
Stainless Steel Flange Grades

Preferred for chemical and marine applications where corrosion resistance is critical.
321 Stainless Steel
Stabilized with titanium, offering high-temperature resistance.
Commonly used in heat exchangers and high-temperature environments.
347 Stainless Steel
Provides enhanced resistance to oxidation and intergranular corrosion.
Suitable for systems exposed to high temperatures and corrosive substances.
Duplex and Super Duplex Stainless Steel
Combines high strength with excellent corrosion resistance.
Used in offshore, oil and gas, and marine industries.
