Temperature sleeve issue
Thread Content
Leaks are occurring at the welds of the temperature sleeves and pipes along the oil pipeline. Why does this happen? What are the specific requirements for manufacturing and welding these temperature sleeves?
I think it’s a matter of the welder’s skill level.
That’s the welder’s job; the casing isn’t our responsibility
When welding the thermometer sleeve joint to the pipe, the connection area did not melt completely; this falls under the scope of pipeline work, and the welder was not careful enough during welding. If there is oil in the oil pipeline, welding is prohibited. If re-welding is required, a fire permit must be obtained and proper fire prevention measures taken.
Well, what about the area where it’s installed in the pipeline? Does that have any impact on it?
Welded components must undergo pressure resistance testing after welding, and temperature sleeves also need to be removed and inspected regularly depending on the flow rate of the medium and its level of radiation; this is usually done during major repairs.
Based on your description, it’s the boss that wasn’t welded properly; it’s a mistake made by an inexperienced welder
