Insulation and Corrosion-Resistant Pipe Basics

Question one pertains to the application of anticorrosive and thermal insulation pipelines in the industry. This topic has been discussed before. Generally, anticorrosive and thermal insulation pipelines are suitable for transporting various media with temperatures ranging from minus 50 degrees Celsius to 150 degrees Celsius. They are widely used in centralized heating and cooling, as well as the transportation of hot oil. They are also employed in thermal and cold insulation projects in industries such as greenhouses, cold storage, coal mines, oil, petrochemicals, and more. This also encompasses thermal insulation projects in aerospace, military, central air conditioning, and municipal pipelines.

The second question concerns the classification of insulation and corrosion-resistant pipes. To clarify, they are categorized into steel-clad steel composite insulation pipes and polyurethane insulation pipes. Within these broader categories, there are further sub-classifications. For steel-clad steel composite insulation pipes, there are internal sliding and external sliding types. The internal sliding version consists of a thermal insulation structure made up of the working steel pipe, silica-alumina, a drag-reducing layer, micro-porous calcium silicate, an insulating layer, stainless steel reinforcing steel strips, aluminum foil reflective layer, polyurethane protective layer, outer steel pipe, and external anti-corrosion layer. The external sliding version, on the other hand, is composed of a working steel pipe, glass wool thermal insulation and heat preservation layer, aluminum foil reflective layer, stainless steel reinforcing strips, sliding guide brackets, air-insulated layer, outer protective steel pipe, and external anti-corrosion layer.
