How to choose between the two standards for stainless steel fittings
Thread Content
For the container nozzles of 304 material, should GB13296 or GB/T14976 be used? What about the pipes used for fluid transport?
For takeover, 14976 is an option; if heat exchange tubes are used, 13296 is required
As long as the calculation works! It doesn’t matter which one is chosen! ! However, the heat exchange tubes of shell-and-tube exchangers cannot use 14976! Choose another standard!

Differences can be seen in the following aspects: 14976 refers to steel pipes used for transporting ordinary fluids, while 13296 refers to heat exchange tubes specifically designed for use in boilers and heat exchangers (the standards governing the development of these two types of products are also different). In terms of standard hierarchy, 13296 is a mandatory standard, whereas 14976 is a recommended standard. As for the types of stainless steel covered, 13296 includes austenitic and ferritic stainless steels, while 14976 applies to austenitic, ferritic, and martensitic stainless steels
