SY/T 5037 & GB/T 3091

Thread Content

For welding steel pipes larger than DN250, how should one choose between SY/T 5037 and GB/T 3091, these two standards? I’ve seen that some municipal design institutes choose SY/T 5037 for water supply and drainage pipes; why not use GB/T 3091 instead? Is there any difference? Please advise, experts

They are formulated by different departments, and the differences aren’t significant; you can take a look at this post for details: https://bbs.hcbbs.com/thread-1655109-1-1.html
