Plastic sleeve steel sleeve buried underground
The outer casing adopts multiple structures to meet the anti-corrosion requirements of extremely harsh
underground environments, significantly enhancing the operational reliability of the pipeline network
The outer sleeve adopts a steel casing. insulation layer, and non-metallic shell structure to provide
multiple protections for the working pipe
The first layer of steel casing adopts a hard or soft insulation structure; The second layer of non-metallic casing adopts high-efficiency polyurethane insulation material
The outermost shell can be made of HDPE or FRP material, both of which meet strict anti-corrosion
requirements
