Are DIN and ANSI flanges compatible?

Jan. 03, 2025

‌DIN and ANSI flanges are not compatible‌. Flanges of different standards cannot be used in combination directly due to differences in size, thread, etc. For example, the differences between ANSI and DIN standards are large, and these two types of flanges cannot be used directly together. Even if the flanges of the two standards look similar, they may not be matched due to slight size differences.‌

In order to solve the compatibility problem between flanges of different standards, conversion flanges can be used. Conversion flanges are a special flange that can convert the interface of flanges of two different standards. For example, when using ANSI standard flanges to connect DIN standard flanges, ANSI/DIN conversion flanges can be used to connect the two. At the same time, since conversion flanges have a greater impact on the safety and stability of the pipeline system, products with stable performance and reliable quality should be selected.‌

How to perform corrosion detection on seamless pipe elbows?

Improper use of seamless pipe elbows can lead to corrosion. Once corrosion occurs, the wall of the seamless pipe elbow typically thins, and localized pitting and corrosion appear. Methods for detecting corrosion in seamless pipe elbows include: Leakage magnetic flux detection is based on the high permeability of ferromagnetic materials.
