Installation Process
To ensure safe and leak-free operation, follow these installation steps:
Verify Specifications
Confirm flange size, pressure class, material, and bolt pattern match the mating flange.
Inspect Sealing Surfaces
Ensure flange faces are clean, smooth, and free from damage.
Install Suitable Gasket
Select gasket material based on pressure, temperature, and media (rubber, PTFE, spiral wound, etc.).
Align Bolt Holes
Position the plate flange accurately against the mating flange.
Tighten Bolts Evenly
Use a cross-tightening sequence and apply uniform torque.
Pressure Test
Conduct hydrostatic or pneumatic testing to confirm sealing integrity.
Tip: Always follow recommended torque values and gasket manufacturer guidelines.

PRODUCT INFORMATION
Flange,also called flange disc or flange. The flange is a part connected between the shaft and the shaft, which is used for the connection between the pipe ends; It is also useful in the flange on the import and export of the equipment for the connection between two devices, such as the reducer flange. Flange connection or flange joint refers to a detachable connection which is connected by flanges, gaskets and bolts as a group of combined sealing structures.
Because the flange has good comprehensive performance, it is widely used in chemical industry, construction, water supply,drainage, petroleum, light and heavy industry, refrigeration, health, water heating, fire, power, aerospace, shipbuilding and other basic projects.
