National Pipe Tapered or also commonly referred to as NPT flange, is a good quality fitting which is typically used in plumbing as well as other industrial uses. A Companion Flange is a kind of fitting which has a hub. These companion Industrial MS Flanges are either known to be socketed or threaded internally such that they can be attached to the pipes of our clients rather easily. There are several benefits to using the Compact Flanges produced in our factory, namely – they are lighter and hence can save up to about 80% on weight. Additionally using a compact Industrial Pipe Flange would mean that our clients have no need to re-tighten bolts at a regular intervals, thereby proving to be a time as well as weight saving alternative. Since our products offer advantages like low maintenance, good strength, reusability, while proving to be efficient and delivering a good performance, we are recognized as one of the best Flanges manufacturer in India.

Generally produced from metals such as aluminum or grade 304 stainless steel, the ISO Flange has a sexless design. While the ISO and KF seals, in terms of design principles tend to be identical, each face of the ISO Flange Dimensions, produced by us is counter-bored or the flange is grooved to receive a metal centered ring with an elastomeric o-ring around its outer diameter.
