Flanges are circular adapters having external or internal ridges. These flanges are helpful to connect two different pipelines, valves, pumps, or any other piping instruments to form an overall piping system. We can attach these flanges using welding or screwing methods.

Incoloy 925 is a nickel-iron-chromium alloy with an addition of copper, titanium, aluminum, molybdenum, and other transition elements. The chemical composition of nickel (44%) in this alloy is sufficient to shield against chloride-ion stress corrosion crackings. Also, molybdenum aids resistance to pitting and crevice corrosions.

Incoloy 925 enhances the performance, stability, and durability of the flanges in elevated temperature areas.  Its chemical components, specifically titanium and aluminum, provide additional strength and toughness to these flanges during the heating process.

Mangalam Metal Corporation can source and supply an exclusive and wide range of pipe flanges across the globe. We use high-quality raw materials to manufacture Incoloy 925 Flanges that meet national and international standards.


Usually, pipes are helpful to transfer gaseous or liquid fluids from one place to another. These fluids might be flammable, toxic, or highly volatile in nature. Thus, engineers use flanges to close the pipelines in a secured manner, to maintain the pressure and composition of the fluids inside the piping system.

Incoloy 925 is an age-hardenable alloy. This alloy provides high-strength and outstanding corrosion resistance in hot and cold-temperature areas. Also, it attains high-yield tensile strength up to 1210 MPa during precipitation-hardening treatment. Thus, flanges can undertake maximum load without fractures or embrittlements.

Flanges are highly versatile. One must consider the face types of the flanges before making an ideal choice for your piping system. The face type of the flanges plays a pivotal role in the performance and durability of the flanges. 

Some of the primary face types include:

  • Flat Face: 

Like its name, the surface of these flange types is totally flat. There is no protruded ridge above its surface, making the gasket cover the full flanges.

  • Raised Face:

These flange types have a small protruded ridge above their surface from one end.  The objective of the raised face flanges is to concentrate the pressure on the smaller gasket areas. Thus, increasing the pressure-containment capacities of the joints.

  • Ring-Join Face:

These face-type flanges have groove cuts into their faces. A gasket is compressed in-between the flanges and the pipes or valves to make a seal. It is the most efficient method of ensuring leak-free flange connections at high pressures.

  • Tongue and Groove:

These types of flanges must have matching grooves and raised sections. It enables them to align perfectly in given positions and provides a repository for gasket connectivity. 

Markings and Packing

Product packaging serves to protect the products inside. Mangalam Metal Corporation effectively ensures all the products are deliverable to our clients securely. In the case of exports, we follow all international standard protocols of packaging.

Often, we export them in wooden cases. We mark our products with Grades, Lot Numbers, Size, Degree, and our Trademark. We also make custom markings on the products as per the requirements of our clients.
