Leak in liquid ammonia intermediate tank
Thread Content
We have a liquid ammonia intermediate tank with a 57-inch connection pipe, and there is a leak at the butt weld; there is still over 20 cubic meters of liquid ammonia inside. Who has any good ways to help us seal it up temporarily?
I can provide a diagram of the butt weld location; will that be helpful to you?
It depends on the level of pressure and the location; pressure-sealing repairs are used to address the issue
It’s the weld at the outlet below, where the flange meets the pipe. There is exudate from two stomata. The pressure is 1.3 MPa
Plugging leaks under pressure, pipe clamps, and sealing materials
Make a special clamp, wrap asbestos rope around the weld, and secure it with the clamp.
