Flat welding flange characteristics and performance classification

Flat welding flanges are tightening flanges and welding flanges. Low pressure small diameters are usually wire contact flanges, high pressure and low pressure large diameters usually use welded flanges, as well as the thickness and number of flanges and diameters vary for different pressures and quantities are different. Depending on the pressure of the pressure, the flange gaskets also have different materials, from low pressure Quadden gaskets, high pressure asbestos gaskets and PTFE gaskets to metal gaskets.

What problems exist when processing stainless steel flanges and how to solve them?

Weld defects: The weld defects of stainless steel flanges are relatively serious. If manual mechanical polishing is used to make up for them, the resulting polishing marks will cause uneven surface and affect the appearance; Uneven polishing and passivation: After manual polishing and polishing, acid pickling and passivation treatment are carried out, making it difficult to achieve uniform and consistent treatment results for workpieces with large areas, and cannot achieve an ideal uniform surface. And its drawbacks include high labor costs and auxiliary material costs;

How are the pressure levels of common flanges classified

Common flanges have certain differences in pressure levels due to their use in different places. For example, large stainless steel flanges are mainly used in high-temperature resistant pipelines in chemical engineering, so there are high requirements for their material pressure performance.

What to pay attention to when designing large flanges

Design and manufacture of tooling: The large flange is composed of two clamping bottom plates that form 900 pieces, two flange support plates, two vertical plates, and four reinforcing rib plates welded together. To ensure the rigidity of the fixture, the welding seams of the connecting plates should be beveled and fully welded, with a welding angle height of 20-30mm.
