Problems related to the matching of threaded ball valves and pipelines

2017-08-21View Original

Thread Content

I am currently using 57*3 pipes, and I need to purchase threaded ball valves. What parameters are required? What size should they be, and what standards apply? Thank you for your assistance

Is the pipe with 57*3 dimensions part of the non-standard series in GB T 17395? For valves, you can refer to GB 12232 and GB 12247; the key parameters include pressure rating and material, etc
