Flanges



A flange allows two pipes to be mechanically connected together, or a pipe to be mechanically connected to a valve, tee, choke or other piece of equipment. The principle of a flange is to use a mechanical force (exerted by the bolts) to pre-load the gasket sufficiently so that when internal pressure (end cap force) is applied, there is enough contact stress between the flanges and gasket to maintain a seal.

We are having experience of manufacturing and exporting Flanges and forgings for more than a decade and that is what makes us India's most reliable and economical manufacturer and exporters of Flanges & Forgings.
We are manufacturing Flanges and Forgings all most in all metals like Stainless, Steel (304, 304L, 316L, 316Ti, 321,310, 317L,904L ) Duplex Steel, Alloy Steel, Super alloys,  Nickel  Alloys (Monel, Inconel, Hastelloy, Alloy 20), LF 2, Brass as per International standards as well as as per customers specific requirement like drawing or Blue print os as per samples provided by the customer.

Blind Flanges

Our organization is engaged in manufacturing of a wide range of Blind Flanges that is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. These flanges are available in various sizes and material and are used to provide positive closer on the ends of pipes, valves or equipment nozzles. Our range helps in easy access to a line once it has been sealed. Further, these are machined to accept a nominal sized pipe to which reduction is being made. This reduction can be a threaded reduction or welded reduction.

Socket Weld Flange

The Socket Welding Flange offered by us is a popular type of pipe flange that was initially developed for use on small-sized high- pressure piping. The fabrication of this type of flange is similar to that of a slip-on flange. Though, the internal pocket of a socket weld flange allows for a smooth bore and better fluid flow. When provided with an internal weld, the static strength of this flange is equal to slip-on flange, but the fatigue strength is 50% greater than double welding slip-on flanges. Smooth bore conditions in such a flange can easily be attained without having to bevel the flange face and, after welding, to reface the socket weld flange as would be required with slip-on flanges. For this reason, the internally welded flange is popular in chemical process piping.

Threaded Flange

Our range of Threaded Flanges finds applications in various industries. These are special type of pipe flanges that can be attached to the pipe without welding. The threads are tapered in order to create a seal between the threaded flange and the pipe as the tapers approach the same diameter. Sometimes a seal weld is also used together with the threaded connection. They are available in various sizes and materials.

Our range of Flanges are made using high grade material, such as Stainless Steel, Alloy Steel, Carbon Steel, Cast Iron, Steel, Aluminum, Brass, Bronze, Monel, PVC and Thermoplastic.

Uses of threaded flanges:

  • Threaded flanges can be fitted to pipes of various sizes without welding and this is one chief benefit for which these flanges are highly demanded.
  • They can be used in extremely high pressure applications, particularly at or near atmospheric temperature, where the necessary post weld heat treatment is not possible.
  • They are ideal for small diameter piping applications.
  • They are economical and time saving devices.
  • These threaded flanges are normally designed for non-cyclic applications.
  • The flanges are suitable to be used in applications where welding is hazardous.
  • They can be used in highly explosive areas.

Plate Flanges

We have been offering a wide range of Plate Flanges to our clients. These are special types of flanges that have raised face and back ups, which are made from quality mill plates. Our flanges have high weld ability & harden ability and are available in different dimensional specifications depending upon the requirements and their applications.

Advantages

Stainless steel plate flanges are produced from quality mill plate. Mill plate produced to the ASTM A240 and ASME SA240 standards is virtually free of voids, non-metallic inclusions and other defects. The inherent corrosion resistance of stainless steel is enhanced by the superior grain structure offered by plate products over forged or cast//c// products.

As companies begin to look at life-cycle costing models, in almost every case, the slightly higher initial cost of stainless steel plate flanges is more than offset by the extended service life and the reduction of the normal maintenance costs.
Stainless steel plate flanges are a widely accepted alternative to cast or forged flanges in low pressure applications.
