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
Product Advantage
Has excellent anti-corrosion performance and strong weather resistance in underground environments
The pipeline as a whole combines the strength of a steel jacket with the anti-corrosion advantages of non-metallic materials
