Stainless steel flanges have sufficient strength and must not be deformed when tightened. The sealing surface of the flange should be smooth and clean. When installing stainless steel flanges, you need to carefully clean oil stains and rust spots. The gasket must have excellent oil resistance and aging resistance, as well as excellent elasticity and mechanical strength. It is necessary to choose gaskets of different cross-sections and sizes according to the shape of the joint to correctly place the stainless steel flange of the equipment.

The tightening force of the stainless steel flange should be uniform, and the shrinkage rate of the rubber gasket should be controlled at about 1/3. In addition, stainless steel flanges are theoretically used according to conventional methods and principles. Stainless steel flanges guarantee quality and use value, and are used and installed according to normal operating specifications.

Stainless steel flange manufacturersIntroduce the choice of materials: mainly used in the food industry and surgical equipment, molybdenum is added to obtain a special corrosion-resistant structure. It is also used as "ship steel" because it has better chloride resistance than 304. SS316 is usually used in nuclear fuel recovery equipment. 18/10 grade stainless steel usually also meets this application level.

The connecting plate of this structure is made of carbon steel or stainless steel. When using carbon steel, the surface must be nickel-plated, and the fixture material is cast aluminum ZL7. The seal roughness of the connecting plate is 20, and there should be no obvious radial grooves. Welding rings are used to save steel. In this construction, the sealing surface must be treated after the welding of the welding ring and the pipe. It is usually used for suspensions with working pressure less than 2.5 MPa. Flat welding flanges with smooth surfaces are not suitable for equipment that is highly airtight to toxic and flammable and explosive media due to poor connection rigidity and sealing performance.

Stainless steel flange manufacturers introduce their applications: Stainless steel flanges are widely used in petroleum, chemical, nuclear power plants, food manufacturing, construction, shipbuilding, paper, medical and other industries. They are used differently in different industries and show value in different industries.
