Direct burial insulation and anti-corrosion pipe is a composite pipe coated with anti-corrosion layer, heat insulation layer and pressure resistant layer on the outer wall of steel pipe. It has the characteristics of small heat loss, strong compressive performance and good anticorrosion and waterproof performance. It is especially suitable for areas with high groundwater level. Compared with traditional buried pipes, it has a series of advantages such as good insulation performance, good anticorrosion performance, long service life, simple construction and installation, small footprint and low cost. It is widely used in the fields of centralized heating, oil transmission, chemical industry, refrigeration and water supply in cold areas. Product structure and main technical indicators 1. product structure: direct buried insulation anti-corrosion pipeline includes the outer wall of steel pipe anti-corrosion layer, insulation layer and anti-pressure protection layer. Anti-corrosion layer: GII epoxy asphalt coating has good resistance to acid, alkali and corrosion resistance. Insulation layer: rigid polyurethane foam. Anti-pressure protection layer: FRP protection layer. It has excellent characteristics such as efficient heat preservation, waterproof, anti-corrosion, heat insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, light weight, high strength, easy construction and not afraid of plant roots and thorns. It has become an indispensable investment in insulation, waterproofing, plugging and sealing of materials in industrial sectors such as construction, transportation, petroleum, chemical, electric power and refrigeration.
Dirèkteman antere izolasyon tiyo, li te ye "pipe nan pipe", divize de etap. Li konpoze -wo dansite polyethylene pwoteksyon kouch kouch%.2c polyurethane rigid izolasyon izolasyon ak asye pipe. izolasyon materyèl rigid rigid polyurethane ak dansite 60kg/m3 80kg/m3. gap ant asye tiyo ak casing konplètman plen ak sèten lyezon lyezon se konsa yon solid antye fòme twa pati twa pati asye tiyo tiyo oubyen casing ak ensiltasyon izolasyon ensiltasyon ant twa pati nan asye tiyo tiyo oubyen casing ak ensiltasyon ensiltasyon .. layer. Polyurethane dirèk ensiltasyon tiyo foam gen mekanik ak chalè konsèvasyon pèfòmans. Under nòmal kondisyon, li reziste tanperati 120 degre. By modifye oswa konbine ak chalè izolasyon izolasyon materyèl li reziste segondè 180 degre. Li apwopriye tout kalite segondè tanperati low tanperati cho dlo tiyo.
