Problem with steam tracing, seeking help
Thread Content
What are the main causes of total leakage in steam tracing pipes, and how can it be avoided? Corrosion? Is the hydrophobicity not good? ......
First, the welding quality is poor because the construction party does not pay enough attention to the construction of the heat tracing pipelines. The second issue is corrosion beneath the insulation layer; when it is not in use during summer, rainwater gets into that insulation layer.
What are the winter temperatures like, and has frostbite occurred?
Where is it leaking? Weld? The vast majority of cases are due to poor welding quality, as the welders do not pay enough attention. If you have him do TIG welding, there are basically no problems.
There are few straight pipe sections; they are all located in low-lying areas or near fittings. Leaks occur relatively less in winter, but after summer, leaks appear everywhere. Steam drain leaks also happen more during this season.
Such a phenomenon is due to the two reasons I mentioned earlier.
Could the original poster first tell us the material of the heat tracing tube? We use carbon steel for the main pipes here, while copper pipes are used at the areas where pipeline heating is applied.
Heating pipes that are used intermittently are prone to corrosion; to ensure long-term performance, it is advisable to invest upfront in stainless steel pipes
We are all made of carbon steel pipes. What is the service life of copper pipes, and are the joints welded or connected using fittings?
