(Summary description)The quality requirements of stainless steel flange connection are as follows: The selection of stainless steel flanges must meet the design requirements. When there is no design requirement, the flange of appropriate form and specification should be comprehensively selected according to the factors such as the maximum working pressure, maximum working temperature, working medium, and material grade of the flange. The flange must be visually inspected before installation. The surface should be smooth, and there should be no defects such as blisters, cracks, spots, burrs that reduce the strength of the flange, and there should be no penetrating scratches on the sealing surface that affect the sealing.

When assembling stainless steel flanges and pipes, use a flange bender to check the verticality of the flanges. When the parallel deviation dimension design of the flange connection is not specified. It should not be greater than 15% of the outer diameter of the flange, and not greater than 2mm. When the two flanges are not parallel and exceed the specified requirements, they must be adjusted, and multiple gaskets must not be used for correction.

Difference analysis between butt welding flange and special-shaped flange
Difference analysis between butt welding flange and special-shaped flange The sealing surface of butt welding flange can be made into three types: smooth type, concave-convex type and tongue-and-groove type. The application of smooth butt welding flange is large. Generally, it is mostly used when the medium conditions are relatively moderate, such as low-pressure unpurified compressed air and low-pressure circulating water. Its advantage is that the price is relatively cheap. Butt welding flanges are suitable for pipelines with large fluctuations in pressure or temperature or pipelines with high temperature, high pressure and low temperature, and are also used for pipelines that transport expensive, flammable and explosive media. The welding method used when connecting the flange and the pipeline of the butt welding flange is butt welding. The welding seam is similar to the welding of pipelines and pipelines. Generally, argon arc welding is used for the bottom of the small pipe diameter, and the cover surface is manually welded. Only use double-sided welding. - Matters needing attention when processing large diameter flanges 05-23
