First, the stainless steel flange should have sufficient strength and must not be deformed during tightening. The flange sealing surface should be flat and clean, and the oil stains and rust spots should be carefully cleaned up when installing the stainless steel flange.

Second, the gasket should have good oil resistance and anti-aging properties, as well as relatively good elasticity and mechanical strength. To install the stainless steel flange, seal gaskets of different cross-sections and sizes should be selected according to the shape of the connection, and placed correctly.

Third, the fastening force of the stainless steel flange should be uniform, and the compression of the rubber gasket should be controlled at about 1/3. In addition, stainless steel flanges are used according to normal methods and principles in actual use. Stainless steel DIN 1478 turnbuckles ensure quality and value in use, and are used and installed in accordance with normal use standards. There are no certain quality and performance issues.

The stainless steel flange is not a simple mechanical part in the usual sense. The stainless steel flange is a mechanical product carrier that contains rich technical connotations and is used in many equipment processing.

Hydraulic oil stainless steel flange is a disc-shaped part, the most common in pipeline engineering, stainless steel flanges are used in pairs. Any connecting parts that are bolted on two planes and blocked at the same time are generally called " "Flange", such as the connection of ventilation pipes, this type of parts can be called "flange parts". But this kind of connection is only a part of the equipment, such as the connection between the flange and the water pump, it is not good to call the water pump "method" "Blue parts". Smaller ones, such as valves, can be called "flange parts". In pipeline engineering, stainless steel flanges are mainly used for pipeline connection. In the pipelines that need to be connected, a variety of flanges are installed, low-pressure pipelines can use wire flanges, and welding flanges for pressures of more than 4 kg. Add sealing points between the flanges, and then tighten them with bolts. Flanges with different pressures have different thicknesses and use different bolts. Water pumps and valves, when connected to pipelines, are also made of parts of these equipment The corresponding flange shape is also called flange connection.
