Key Features
-
Superior Sealing Performance
Manufactured to national (GB) or American (ANSI) flange face standards and paired with high‑temperature, pressure‑resistant gaskets to ensure leak‑free connections. -
High Pressure Rating
Available in carbon steel, low‑alloy steel, stainless steel, and other materials to meet requirements from low pressure up to 25 MPa. -
Easy Installation & Maintenance
Flange faces are bolted symmetrically and evenly for rapid assembly. For routine inspections or service, the flange connection can be disassembled quickly, saving maintenance time. -
Corrosion & High‑Temperature Resistance
Surface treatments include hot‑dip galvanizing, electrophoretic coating, or epoxy spraying. Stainless steel options (304/316L) are available to withstand acidic, alkaline, salt‑spray, and high‑temperature environments. -
Complete Range of Standards & Customization
Compliant with ANSI, DIN, JIS, GB and other international/domestic standards. Nominal diameters from DN15 to DN1200 are stocked, and non‑standard sizes can be custom‑manufactured per project requirements.

Installation & Maintenance
-
Installation
-
Align flange faces and insert the appropriate gasket;
-
Tighten bolts evenly in a crisscross pattern to the specified torque;
-
Inspect gasket compression, perform a pressure test, and then commission the system.
-
-
Maintenance
-
Regularly check bolt tightness and inspect flange gaskets for wear;
-
To replace a gasket, loosen bolts, remove the old gasket, clean flange faces, install a new gasket, and retorque bolts to specification;
-
For highly corrosive or high‑temperature services, shorten inspection intervals to ensure long‑term reliability.
