Everyone, take a look at this flange marking
Thread Content
This is equipment purchased by my factory. The connection flanges – from the markings on them, it’s not clear which standard they follow; it seems to be 16MND low-temperature steel flanges, but I’m not sure what standard that corresponds to. I’d appreciate any insights from those who know more
The flanges made of 16MnD low-temperature steel are likely to comply with Chinese **standards or industry standards; it is recommended to check the documents accompanying the equipment or contact the supplier to confirm the specific standards. .
This does not match the internationally standard marking conventions; it is recommended to check the archives to determine which standard is being followed. It is unlikely to be a standard such as GB, HG, JIS, or DIN. Looking forward to your response.
Can’t it be filmed in reverse? It’s hard to watch like this
