Steel sleeve tšepe kwahelang pipe .
Direct buried kwahelang phaephe, e tsejoang hape e le "phaephe phaephe", e bopilwe ka "mekhoa-mehato e mebeli", e leng e bopilweng ka segokanyipalo phahameng polyethylene ka ntle tšireletso lera, polyurethane thata polasetiki kwahelang thepa le tšepe pipe. The inselation lera lintho tse bonahalang ke polyurethane e thata e eketsang 60 kg / m3, e ka tlung kg / m00, e ka botlalo. casing, and has a certain bonding strength, so that the steel pipe, the jacket pipe and the insulation layer form a solid whole. Polyurethane directly buried thermal insulation pipe foam has good mechanical properties and thermal insulation properties, usually can withstand high temperature 120℃through modification or combination with other thermal insulation materials can withstand high temperature 180℃, suitable for all kinds of cold, hot water high and low temperature pipeline thermal insulation Boenjiniere. .
Polyurethane directly buried thermal insulation pipe is suitable for the thermal insulation engineering of various media in the range of-50℃- -150℃. It is widely used in urban central heating, heating room, cold storage, coal mine, oil pipeline port, chemical industry, natural gas pipeline, power directly buried, central air conditioning pipeline insulation, cable pipe, steam insulation pipe and other industries of thermal insulation and cold protection Boenjiniere. .
