How should pressure pipes with casings be inspected? ? ?
Thread Content
Our facility has a unit that requires very high temperatures, so sleeves have been added outside the pipelines. It’s time for the first regular inspection now. I would like to ask how such pipes should be inspected? ? ? There’s no need to cut through the outer pipe in order to inspect the inner one, right? ? ? When we asked the testing agency, they said there was nothing they could do. But we can’t just accept that – if it’s not tested, it can’t be used. . .
Just choose to break down the monitoring segment.
Pressure test the inner tube! Is the outer sleeve there for heat protection or insulation? Can a small hole be drilled at the low point?
Bro, it’s very simple. . . But do you think it’s possible? ? ?
The outer sleeve contains steam, which is used for heating. . . So if work doesn’t stop, how can it be done?
It can be inspected, but the cost is relatively high. Special automated robots can be used for the inner tubes; there are a few companies in the market that can provide such services, but the prices are not low
It’s better to send a picture, so as to avoid any misunderstandings. If such things are the case, monitoring points should have been set up at the initial installation stage. Devices like this are not built casually just because one thinks so.
It’s about the tubes and sleeves; when the temperature of the medium inside the inner tube drops, it condenses, so steam is used in the outer tube. . . What do you mean by the testing points? ? ? Actually, I can put another set of such devices in use right away; I can propose this to my supervisor
Send a picture to take a look – the approximate specifications of the pipes, which layer of the pipe is prone to corrosion, and whether it’s offline inspection or online inspection. Send a picture, and let’s engage in the discussion together.
