Leading Manufacturer of GOST 12821 Blind Flanges, Check Price list of GOST Standard Flanges

A GOST module is a Russian grade steel that adapts to different international standards. The GOST Flange are medium or small diameter flanges that operate in different applications. These flanges are designed in sizes of 1/2 NB to 48 NB and in pressures ratings of Class 1500, 1500, 400, 900, 300, and PN designations. A 12821 80 flange can be designed in screwed, forged, threaded, or plate configurations. These flanges can be coated with a lubricant to give them enhanced corrosion and oxidation resistance properties in different environments. The versatile GOST 12821-80 Flanges can be manufactured in different alloy and steel grades. These flanges are commonly seen in refineries, gas processing, petrochemicals, offshore drilling, fertilizers, pharmaceutical, water pipelines, power generation, pulp, and paper companies, etc. The GOST Standard Flanges are manufactured in sizes of DN 15 to DN 1200. These flanges connect piping fixtures of different sizes and provide support and stability to these modules in treacherous conditions. These quality assured products are manufactured with the best in class raw materials and latest technological systems.

Nace certified GOST 33259 Flange and GOST 12821-80 Slip On Flange supplier in Mumbai

A Gost Weld Neck Flange is designed with a long protruding hub. These flanges are butt-welded to the grade and allow the module to bind piping components in high-pressure and temperature applications. The Gost Blind Flange is designed without any face type or a boring center. These flanges help in terminating the flow of fluids and gases in the system. They are usually bolted to the module allowing room for repair and maintenance. The versatile GOST 12821 Stainless Steel Flanges are high-strength components that are designed with an 11% content of chromium. The content embedded in these flanges gives them enhanced resistance to corrosive media across stress-induced environments. These flanges can be availed in different shapes and sizes to suit different project requirements.
