How to avoid deformation of large-diameter butt welded flanges during production?

Some users may have encountered situations where the flange is deformed due to stress during the production of large-diameter butt welded flanges. So, let Fuze large-diameter butt welded flange manufacturer take you to understand how to avoid deformation during the production of large-diameter butt welded flanges?

The main methods to avoid deformation during the production of large-diameter butt welded flanges are to increase the system stiffness (especially the stiffness of weak links in the process system) and reduce the load and its changes.

1. Large diameter butt welded flanges improve system stiffness

A、 Reasonable structural design of large-diameter butt welded flanges

(1) Minimize the number of large-diameter butt welded flange connection surfaces as much as possible

(2) Prevent the occurrence of local low stiffness links in large-diameter butt welded flanges

(3) The structure and cross-sectional shape of the base and support components should be reasonably selected for large-diameter butt welded flanges

B、 Improving the contact stiffness of the connection surface with large-diameter butt welded flanges

(1) Improving the quality of joint surfaces between parts in large-diameter butt welding flange machine components

(2) Preloading the components of large-diameter butt welding flange machine tools with loads

(3) Improve the accuracy of the positioning reference surface for large-diameter butt welded flange workpieces and reduce its surface roughness value

C、 Adopting a reasonable clamping and positioning method for large-diameter butt welded flanges

2. Reduce the load and its variation on large-diameter butt welded flanges

A、 Reasonably select the geometric parameters and cutting parameters of large-diameter butt welding flange cutting tools to reduce cutting forces

B、 Grouping of raw materials to ensure even processing allowance during adjustment.
