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.
