The sliding method of the steel-jacketed steel thermal insulation
steel pipe determines the structure.
1. Internal sliding-type: The thermal insulation structure is composed of working
steel pipe, aluminum silicate, drag reduction layer, microporous calcium silicate, thermal insulation layer, stainless steel fastening strip, aluminum foil reflective layer, polyurethane thermal insulation layer, outer
steel pipe, and external anti-corrosion layer. composition.
2. External sliding-type: The thermal insulation structure is composed of a working
steel pipe, glass wool thermal insulation layer, aluminum foil reflection layer, stainless steel fastening belt, sliding guide bracket, air thermal insulation layer, and an outer protective
steel pipe, and outer anti-corrosion layer.
