Which standard governs the notation of flexible metal hose codes?
Thread Content
I have a question: what is the standard for this image? It’s not listed in GBT14525
The notation method for metal hose codes follows the GB/T 14525 standard \"Technical Requirements for Metal Hose Assemblies\". If no relevant information can be found in this standard, it may be necessary to consult other relevant standards or updated versions of the standard. .
This standard does not include a representation method similar to that in the image, so I’m asking what the meaning of the code used to denote metal hose products is
It’s obvious that it was set by oneself; it definitely won’t be found in the standards
Which standard governs the notation of flexible metal hose codes?
GB∕T 12777-2019 General technical requirements for metal bellows expansion joints
The notation method for metal hose codes primarily follows the **standard GB/T 14525-93**, and is expressed by taking into account specific specification series, tube material, connection methods, and other relevant information. When purchasing and using it, it is recommended to refer to relevant standards and consult the manufacturer for accurate information.
