How to assess the quality of a necked flat‑weld flange
How do you assess the quality of a necked flat‑weld flange? This is a question many customers care about. Here are five methods to help you accurately evaluate product quality.
1. Compared with quoted prices, flanges on the market are cheapest when they are forged; cast and forged flanges follow, with fully forged flanges being the most expensive.
2. In destructive testing, flanges are classified as follows: forged flanges may exhibit porosity, while fully forged flanges do not; cast‑forged flanges sometimes exhibit cracks.
3. In terms of flange dimensions and surface finish, forged flanges typically exhibit a negative square‑inch tolerance of 1–5 mm, with irregular edge chamfers and rough burrs in the bolt holes; forged flanges are relatively small.
4. Weight: For the same proportion of flanges, forged components are lighter than cast ones.
5. Based on supplier selection, it is best to choose a manufacturer, as they offer quality assurance.
