CRP/CRB series products are for buried steel pipeline and overhead Weld corrosion-proof and insulation pipe insulation fill mouth and design. It is by the radiation crosslinking polyolefin base material and special seal glue compound and into, special seal glue with polyolefin base material, steel surface and solid epoxy coating can form good adhesive. WSS heat shrinkable belt in heating installation, base material, in radial in radial shrinkage while, internal composite sub melted, tightly wrapped in filling mouth place, and substrate together in pipe outer forms a solid anticorrosive body, excellent wear resistance, corrosion resistance, impact resistance and good uv light aging performance.
