Can the material for the steam cylinder barrel be 20 GB3087?
Thread Content
I’d like to ask gently: A pressure vessel manufacturer is currently producing a steam distribution cylinder, which falls under Category I pressure vessels. The cylinder body is made of material 20 GB3087, which is not within the range of materials specified in GB150 for steel pipes. Is this acceptable? Thank you
No, because GB150 does not cite this standard
Of course. TSG 21 does not state that it is forbidden to use materials based on ×× standards; it only requires that the performance and quality of such materials meet the relevant ** or industry standards. :lol
Although there isn’t much difference between 20G and 20#. However, the 3087 standard is not part of the GB150 scope; it is recommended to use 8163 instead
3087 has a higher quality than 8163
It is not allowed; the standard definition of GB150 states that low-pressure boiler tubes cannot be used in containers
GB150.2 and Appendix A do not specify this material, so it cannot be used!
I’m asking shyly: could you take a screenshot of the definition?
How to choose without an allowable stress?
