Flange Manufacturers, suppliers and stockists in India-Low Prices, Best Quality and super fast delivery for flanges.

We are manufacturing flanges in many different sizes and material standards. We have a huge stock of flanges in carbon steel, alloy steel, stainless steel and special metals.Most of our production of carbon steel flange and stainless steel flange are exported out of India to more than 15 countries.

A steel flange (forged,cut from plate or rolled) comes in a variety of shapes and sizes to suit different applications. A flange is usually in the shape of a round disc and is used to connect two pipes together or to connect a pipe to a pressure vessel, valve, pump, integral flanged assembly or other component. A flange comes with a hole for bolts around the rim. Bolts are used to connect two flanges which are typically attached to pipe ends with a gasket in between.

Flanges are available in multiple shapes as welding neck, Forged Flanges, blind flanges, slip on flanges, lapped joint flanges, threaded flanges, socket weld flanges, long weld neck flanges, weldo/nipo flanges, orifice flanges, reducing flanges, flat flanges, loose flanges, RTJ flanges, SORF flanges, square flanges, SWRF flanges, Expander flanges, WNRF flanges, Ring type joint flanges, Groove and tongue flanges, high hub blinds flanges, screwed flanges, forging facing flanges, 150# flanges, 300# flanges, 600# flanges.

A flange can also be a plate for covering or closing the end of a pipe. This is called blind flange. This flanges are considered to be internal components which are used to support mechanical parts.

Weld neck flanges

This type of flange has a neck that is welded to the end of pipes. It is used for high-pressure application to reduce the concentration of stress. Generally machined from a forging, these flanges are typically butt welded to a pipe. Weld-neck flanges have a higher life expectancy than slip-on flanges under duress.

Slip on Flanges

Slip-on flanges or SO flanges are commonly lower in price than weld-neck flanges, and to this effect are a popular choice for many users. These pipe flanges slip over the pipe. They’re manufactured with an inside diameter that is slightly bigger than the top and bottom of the flange.

Blind Flanges.

A blind flange is a round plate which has all of the relevant boltholes but no centre hole and because of this feature this flange is used to close off the ends of piping systems and pressure vessel openings. It also permits easy access to the interior of a line or vessel once it has been sealed and must be reopened. The blind flange is used to close ends of piping systems. It is a kind of round plate with no centre hold but with all the proper bolt holes. This blind flange is available in various sizes and materials and used to provide positive closure on the ends of pipes, valves or equipment nozzles. This flange helps in easy access to a line once it has been sealed. The blind flange is sometimes a custom made or machined to accept nominal size pipe to which reduction is being made. Blind flanges are commonly used in petrochemical, pipe engineering, public services and waterworks. Blind pipe flanges are often used for high-pressure applications.

Socket weld flange

A socket weld flange has a female socket in which pipe is fitted. Fillet welding is done from outside on the pipe. The socket-welding flange is the same as the slip-on flange except it has a bore and a counterbore dimension. The counterbore is slightly larger than the O.D of the matching pipe, allowing the pipe to be inserted in the flange similar to a slip-on flange. The diameter of the smaller bore is similar to the I.D of the matching pipe. A restriction is built into the bottom of the bore which sets as a shoulder for the pipe to rest on. When using a socket weld flange, the inner diameter needs to be similar to the inner diameter of the pipe. The socket flange is only suitable for pipes with a nominal diameter of 150 or less.


Lap joint flanges are used on piping fitted with lapped pipe or with lap joint stub ends with the combined initial cost of two items being approximately one-third higher than that of comparable welding neck flanges. Lap joint flange has two components, a sub end and a loose backing flange. Stub end is butt-welded to the pipe and the backing flange freely moves over the pipe. The backing flange can be of a different material than stub material and normally of the carbon steel to save the cost. The lap joint flange is practically identical to a slip-on flange except it has a radius at the intersection of the bore and flange face. The radius is necessary to have a flange accommodate a lap joint stub end. Normally, a lap joint flange and a lap joint stub end are mated together as an assembly system.

Threaded Flange

Threaded flanges are also known as screwed flanges, and it is having a thread inside a flange bore which fits on the pipe with matching male thread on the pipe. Threaded flanges are widely demanded as pipe flanges i.e called as threaded pipe flanges used in different industrial applications. This type of joint collection is speedy and simple but not suitable for high pressure and temperature applications. Threaded flanges are mostly used in utility services such as air and water. The threaded (screwed) flange is similar to the slip-on flanges, but the bore is threaded. Its chief merit is that it can be assembled without welding, explaining its use in low-pressure services at ordinary atmospheric temperatures, and in highly explosive areas where welding creates a hazard. Threaded flanges are not suitable for use where the temperature of the pipe changes sharply or the temperature is higher than 25°c and lower than -40°c.

ring joint flanges

Our range of stainless steel ring joint flanges is highly appreciated for strength, durability, reliability, corrosion resistance and close tolerances. These stainless steel ring joint flanges conform to various Indian and international quality standards. Used in a number of industries, these stainless steel ring joint flanges are supplied in various dimensional specifications.

Orifice flanges

Orifice flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used. In other words, orifice flanges are used with orifice meters. The basic purpose for this is to measuring the flow rate of either gases or liquids in the respective pipeline. These flanges are used in various industrial applications and are available in various sizes and materials. All orifice flange units are supplied with the plate, pressure connection holes, and jack screws.
