Just open the lowest valve and discharge directly!
Install traps at low points in pipelines； Drain water from the equipment drain valve. Generally, a water trap (with standards and regulations) needs to be added to a certain distance on the pipeline.
Just release it from the lowest point, the requirements are extremely strict.
Saturated steam is the only way to pass steam tracing through the pipeline to dry the inner pipe.
Discharge from a low place first, then pressurize with dry air or nitrogen and then discharge from a low place. If the air volume is sufficient, it can also be blasted or continuously purged. This post was last edited by Sky Eagle on 2009-3-27 18:00 ]
Which standard number is the relevant specification?
Thank you for your discussion. This pipe normally carries materials. It is probably not possible to install STEAM TRAP. It would be dangerous to open it for pouring and draining... :handshake This post was last edited by winbook99 on 2009-3-28 19:32 ]
