We are also one of the leading suppliers of Duplex Steel Flanges and other related products.
Carbon Steel Forged Flanges are made by processing metal under tremendous pressures, which increases its tensile and fatigue strength. These flanges offer a consistent surface polish and adequate surface porosity. Our company, a Carbon Steel Flanges manufacturer in India, employs rigorous testing techniques to provide the best products in the industry.
The Low Temperature Carbon Steel Flanges are intended to operate in cryogenic temperatures without cracking under extreme cold. These flanges can be made in raised, flat, or rtj configurations. A Carbon Steel Raised Face Flange features a raised surface above the bolting location, which allows it to securely seal the component. These flanges can be sealed using soft, semi-metallic, or flat gaskets.

Every Standards have clearly requirements for steel flanges’ marking style, usually the marking words include seller’s Logo, buyer’s Logo (OEM), standard number, flange’s type, flange’s pressure, flange’s size, flange’s material, place of origin, heat number and other words for convenient to trace. If the flanges repaired by welding, it must mark on flanges showing this flange repared by welding. If the flange’s dimensions (OD, ID, PCD, Thickness, Holes number, Holes diameter, Tolerance etc) are different with the normal standard, it also must mark on flanges where it is different with normal ones. Another important place is heat number marking, it is the tracing base for every piece flange, and from the heat number we can trace to the beginning of raw material import.
Carbon Steel Stainless Steel Flanges and Stainless Steel Slip On Flanges are delivered with or without surface protection, as determined by the manufacturer.
The company delivers Carbon Steel Flanges in standard packaging, without surface protection or end protectors (caps). Special packaging, protective covers, and end protectors (caps) can be agreed upon.
