Leading SS Flanges Manufacturer & Supplier In India

As a leading Stainless Steel Flanges Manufacturer In India, Ashwin Impex provides superior quality SS flanges with exceptional ductility, resistance to corrosivity, and strength. The beneficial properties of stainless steel flanges are due to their material composition which consists of low carbon steel with a minimum chromium content of 10% or higher by weight....

A flange is a ring of stainless steel designed to couple multiple sections of pipes to a pressure vessel, pump, valve, or any other type of industrial equipment. SS Flanges Manufacturers provide flanges that are usually welded into the pipes or mounted with the threaded screw on the industrial equipment.

SS flanges are manufactured by using multiple manufacturing techniques viz. Casting, cutting from rolled plate material, or forging.

Some of the common types of flanges offered by Stainless Steel Flanges Manufacturer in India are long welding neck, lap join, welding neck, slip-on, socket weld, threaded and blind flanges. The purpose of the industrial application differs. For instance, pipes with slip-on-pipe flanges can be easily assembled and disassembled.

What are Stainless Steel Flanges

Stainless steel flanges are a simple engineering solution used to link joints in a piping network. They offer many advantages over the welding. For eg, two same-diameter steel pipes can be merged together using electric welding but the disadvantage of this process is that it is difficult to dismantle once the welding is done. The only solution is to slice the connection by using a cutter or electric welding machine. A flange solves this problem by providing an internal or external edge for connection. When the pipeline has to be repaired, it can be easily dissembled.

Type of MS & SS Flanges

Weld neck flange
Welding neck flanges can be easily recognized because of their long tapered hub that gradually expands to the wall thickness from a pipe or fitting. The long tapered hub is of enormous importance for an industrial setting. A few of the major applications of weld neck flange can be found in high pressure, sub-zero, or elevated temperature setups. It is generally welded to a pipe or fitting with a single full penetration, V weld (buttweld).

Slip-on Flange
The slip-on flanges offered by ss flange manufacturer can be easily fitted and welded in different pipes and industrial equipment. In order to connect, they are slipped over the pipe and then welded from inside and outside. Such types of connections provide strength and durability to the infrastructure at large. But, prevention against leakage is one of their biggest advantages. These properties make it ideal for low-pressure industrial applications.

Lap joint flanges
By design, lap joint flanges don’t have a raised face like other types. In the industry, they are utilized in conjunction with a “Lap Joint Stub End”. They can be used at all pressures and are available in a diverse range of sizes/ dimensions. They are generally used in equipment/ machinery that requires frequent dismantling. In addition, the lap joint flanges can be used where parts of the infrastructure get eroded or corrode quickly.

Blind flanges
The blind flange is a circular plate that consists of all the relevant boltholes but has no center hole. The purpose of no center hole is to close off the open ends of a piping system. It is also applied at the end of the pressure vessel opening and valves. Blind flanges are highly stressed flange with respect to internal pressure and bolt loading.
