Regarding oxygen safety valves and check valves
Thread Content
Dear colleagues, please share the manufacturers and materials used for the oxygen safety valves and central oxygen check valves in your companies. Thank you!
The internal components of oxygen pipeline valves must have their bolts welded, otherwise they are prone to loosening over time due to operation.
May I ask why? Are there any coal chemical enterprises that do this? Are it those internal components that require welding?
I mainly want to know what type and material your safety valves and check valves are made of? Which company manufactured it?
Imported 625s; there are ones from Spain and the UK as well.
Made of Monel; feel free to contact me if there are any issues.
