India's Top 10 Carbon Steel Flanges Manufacturers, Suppliers & Exporters in 2025
Carbon Steel flanges are a straightforward engineering solution that is vital to the industry. Flanges, in simple words, are used to connect joints in a piping network. As a result, they are one-of-a-kind couplings for connecting pipes, with numerous advantages over welding these joints. Electric welding, for example, can join two steel pipes of the same diameter. The shortcoming of this method is that after it has been welded, it is difficult to remove. A flange solves this problem by providing a connecting edge on the inside or outside. If a flange is used, a gasket seal can be placed into it and then secured with a screw cap. This design allows for easy disassembly when the pipeline fails or needs to be updated. Steel flanges make cleaning, inspection, and customizing simple. They are most commonly circular, but they can also be square or rectangular. The flanges are built for certain pressure ratings and are bolted together and welded or threaded to the piping system. Because flanges contain less carbon, they take longer to oxidize. Wide or irregular grains result from improper forging processes. The casting flange is, therefore, more susceptible to hardening, cracking, and forging than the casting flange. There are many types of flanges, and the most common ones used for industrial applications are discussed below.
Most Common Types of Flanges
1. Welding Neck Flanges:
The welding neck flanges are referred to as the high hub flange. It aims to transfer stress from the flange to the pipe, hence reducing excessive stress concentrations at the flange's base. A weld neck flange, also known as a high-hub flange or a tapered hub flange, is a type of flange. A weld neck flange is a spherical fitting with a protruding rim around the circumference. These flanges are usually forged from steel and welded to the pipe. Several holes are bored into the rim to allow the flange to be attached to another flange.
2. Slip-On Flanges:
Customers prefer slip-on flanges, also known as SO flanges since they are often less expensive than weld-neck flanges. These flanges are designed to glide over the pipe. They have an interior diameter that is slightly greater than the pipe's exterior diameter. Fillet welds join the pipe to these attachments.
3. Socket Welding Flanges:
Socket-Weld Pipe can be placed into a female socket on flanges. Fillet welding is done on the pipe from the outside. The pipe can be inserted into the flange like a slip-on flange since the counterbore is slightly larger than the matching pipe's O.D. The socket flange can only be used on pipes with a nominal diameter of 150 or less.
4. Lap Joint Flanges:
Lap joint flanges are used on pipelines with lapped pipe or lap joint stubs. A lap joint flange has two parts: a stub end and a loose backing flange. The stub end of the pipe is butt-welded to it, allowing the backing flange to freely pass over it. A lap flange is used when frequent dismantling is required and space is restricted.
5. Threaded Flanges:
Threaded flanges, also known as threaded pipe flanges, are extensively used in several industrial applications as pipe flanges. Although this type of joint connection is quick and simple to use, it is not suitable for situations that need a lot of pressure or heat.
