We manufacture and supply a seamless range of flanges and pipe fittings to a number of industries including Petrochemical, Refinery, Mechanical, and Oil & Gas around the world. We provide stainless steel pipe fittings like elbows, reducers, pipe bends, cap, stub end, tee’s and also offer various types of flanges which include the threaded flanges, blind flanges, weld neck race face , socket weld flanges, lap joint flanges and slip on flanges to name a few. We supply a wide variety of these products in different grades of material including stainless steel, aluminium, and nickel alloys.
We are today a renowned manufacturer and supplier of the industry, supplying our patrons’ quality pipe fittings and flanges at a highly competitive price. With an increase in demand and thorough quality requirements across all industrial projects, we guarantee an expertise and infrastructure facilities to deliver the same. All our products are manufactured and developed to meet industry standards and fit the requirements of every client.
Our range of flanges and pipe fittings successfully caters to various industries and to ensure they meet the individual requirement, we offer these products in various dimensions. We produce flanges in the size range from ½” to 40”.
Our flanges division encompasses an integrated forge shop with automated machine centers that manufactures all types of pipe fittings i.e. flanges, butt welding fittings in various specifications (ASME/ ANSI, EN, DIN).
Our manufacturing facilities is well equipped to manufacture various types of flanges namely:
Blind Flange- A Blind flange is round plate which has all of the relevant bolt holes but no centre hole, and because of this feature this flange is used to close off the ends of a piping systems and pressure vessel openings. It also permits easy access to vessels or Piping systems for inspection purposes.
Weld Neck Flange- Weld Neck Flanges have a long tapered hub and are often used for high pressure applications. These flanges are designed to be joined to a Piping system by Bun Welding. The Neck, or Hub, transmits stresses to the Pipe, reducing stress concentrations at the base of the Flange. The gradual transition of thickness from the base of the Hub to the wall thickness at the Bun Weld, provides important reinforcement of the Flange. The bore of the Flange matches the bore of the Pipe, reducing turbulence and erosion. These flanges are ideal for extreme fluctuations of temperature and in environments where there may be high pressure or high temperature being dealt with depending on the grade of raw material.
Slip-on Flange- These are easily fitted and welded into different pipes. Slip on pipe flange is slipped over the Pipe and then welded both inside and outside to provide sufficient strength and prevent leakage. These flanges are ideal for lower pressure applications. This Flange is used in preference to Weld Necks by many users because of its lower cost and the fact that less accuracy is required when cutting pipe to length.
Socket Weld Flange- These flanges are attached by inserting the pipe into the socket end. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. Socket-weld pipe flanges are mainly used for smaller sizes of high pressure pipes.
Threaded Flange- Threaded flanges are similar to slip-on pipe flanges except the bore of threaded pipe flange has tapered threads. These flanges are ideal for relatively low pressure piping systems. Threaded flanges are used with pipes that have external threads. The benefit of these pipe flanges is that it can be attached without welding.
Lap Joint Flange- Lap Joint Flanges slide over the pipe and are most commonly used with Stub End Fittings. A pipe is typically welded to the Stub End and the Lap Joint pipe flange is free to rotate around the stub end. Lap Joint pipe flanges are often used for applications that require frequent dismantling. Threaded pipe flanges are often used for small diameter, high pressure requirements.
