Abstract:

The effect of pipeline insulation in refineries involves many aspects such as safety, energy saving, investment economy, which is of great significance to the safety of device operation, process temperature, energy saving and improving the sensory quality of refineries. The typical problems of pipeline insulation of 27 refineries were summarized. In terms of thermal insulation materials and structure, there were problems such as irrational thermal insulation materials, irrational thickness of thermal insulation thickness and insulation structure simplification. In terms of the construction quality, the frequency of problems was counted for the insulation layer and protective layer construction. The data showed that the elbow of pipeline insulation was the weakest link. Causes and possible consequences of the problems were discussed. Corresponding improvement measures and suggestions for the protection of finished pipeline insulation were put forward.

Key words: refineries, pipeline, thermal insulation material, thermal insulation thickness, thermal insulation structure, construction quality
