Galvanized Flanges

Are you looking for Hot Galvanizing Blind Flange Manufacturer in India, Check latest price list of ASTM A123 grade 85 Weld Neck Flanges

Galvanization is a process where a coating of zinc is applied with steel to give it protection against rusting. Galvanized Flanges are high-strength modules that are seen in water supply systems and outdoor systems. These flanges have enhanced resistance to corrosive and oxidative media across stress-induced setups. The coating on the Galvanized Pipe Flange corrodes before it reaches the steel grade. The flanges can be easily threaded, bolted, or welded in place following standard processes. A Galvanized Steel Flange can be hot or cold galvanized to meet specific requirements. These flanges showcase a long service life and can be availed at lower prices across all our outlets. The versatile Galv Flange is produced by our renowned workers with the best raw materials and latest technology. They can be customized in different shapes and sizes as per requirements.

Biggest Supplier of Hot Dipped Galvanized Steel Weld Neck Flange in India, check HDG Threaded Flanges Chemical and Mechanical Properties

The Galvanized Threaded Flanges are designed with threads that directly align to the subsequent pipe modules. These flanges can be easily removed and installed allowing room for maintenance and cleaning. They are preferred in low-pressure and temperature applications. Galvanized Blind Flanges are high-strength grades designed without a face or boring center. These flanges are designed with bolts that help terminate the flow of fluids and gases in the system. The Square Galvanized Flanges are robust modules that are utilized in different hydraulic systems to connect pipe or piping components. They are square in shape and can be designed as per different pressure ratings to fulfill project requirements. The versatile Galvanized Lap Joint Flanges are designed with a two-component assembly with a stub end and a lap-joint ring flange that is placed over the flange component. These flanges are very durable as they have the freedom to swivel and are not in direct contact with the fluid flow in the system.
