Help needed: Standards for valves and pipelines

2017-02-20 View Original

Thread Content

Hello everyone. 1. We have a DN65 steam pipeline that needs to cross a road, which is 6 meters wide. Is the span large? Which standard specification should be implemented? 2. What standards apply to stop valves and ball valves submitted for approval? Thank you

The standards that valves must comply with depend on the system specified for the project; national standards include GB 12234 and GB 1235. If using the American standard, API600 and API623 are adopted. A span of six meters is sufficient
