What Is API Flanges?


These forged API Flanges have been designed in accord with the industrial standards. The API Raised Face Flange has been fabricated using best quality material raw material, from our vendors and is sourced responsibly. Stainless Steel API Rtj Flange, specifically speaking grade 316 is known for its excellent performance at elevated temperature along with good resistance against corrosion ( pitting, chlorine stress related corrosion cracking and against some acidic solutions) and durability. Generally, most of our existing clients in our customer base prefer getting the Stainless Steel API Flanges produced either in austenitic stainless steel grade 304, as it is cost efficient or grade 316, that is if they require additional corrosion resistance properties at higher temperature with good mechanical strength.

Api 6a Flanges Use High-pressure Temperatures

Api 6a Flanges Use High-pressure Temperatures?

API Blind Flange has been fabricated with the wall thickness being or matching the same dimensions, as that of the matching pipes. Our range of API Flanges Material takes into account the requirements of numerous other industries. As manufacturers we recommend using the API Flanges Standard ideally at high pressure, as well as varied cold or hot temperatures.

The API Slip On Flange manufactured in our factory meets the requirements of various industries such as  heavy engineering, automobile, railways as well as pipeline engineering. These flanges are available in Standard Specifications, and 10000# API Flange Dimension. Our range of API Weld Neck Flange could also be customized as required by all of our Clients. As expected of Copper Nickel API Blind Flange, this component has good resistance to biofouling, which in turn is caused by microbes in the surrounding area. This resistance property against biofouling of the copper nickel alloy based API Integral Flange is inherently present.
