I’d like to ask the experts: is there any way to remove grease from valves after they have been installed?
Thread Content
The medium is oxygen. The factory forgot to degrease it. The valve has been installed and sent out. As a result, the customer called to ask if degreasing was possible, seeking expert help. . . The valve has already been installed; is it possible to degrease it again?
Go back, replace the valve, or have the manufacturer send someone to assist; they will cover the costs.
Cut the valve out of the pipeline using a special perforated blind flange, and perform local degreasing
The installed valves can be degreased; industrial pipeline construction standards specify that the circulation method can be used for degreasing
Remove it after degreasing and then reinstall it; I remember one of our clients did exactly that last time.
