What are the main inspection items for flanges
Steel pipe flanges are widely used in chemical industry, piping, rail transit and pressure vessels, and their inspection covers raw material, geometric dimensional, visual surface, non-destructive, performance, sealing face and third-party type tests.
- Manufacturing & Quality
What are the machining processes for flanges
The flange machining process starts with raw material cutting, using qualified forged blanks or round steel cut to drawing dimensions, with material certificates supplied and heat lot numbers marked.
