Application Data of Polyurethane Thermal Insulation Pipe What is the Data of Thermal Insulation Layer of Polyurethane Thermal Insulation Pipe
聚氨酯保温管运用资料聚氨酯保温管保温层资料是什麼聚氨酯保温管保温层资料爲密度60kg/m3至80kg/m3的硬质聚氨酯泡沫，充沛添满钢管与套管之间的间隙，并具有一定的粘接强度，使钢管、外套管及保温层三者之间构成一个结实的全体。
Polyurethane insulation tube application information polyurethane insulation tube insulation layer information is what polyurethane insulation pipe insulation material data for density 60kg/m3 to 80kg/m3 rigid polyurethane foam, fully filled the gap between steel pipe and casing, and has certain bonding strength, make the steel tube, outer tube and insulation layer between the three constitute a solid whole.
聚氨酯直埋保温管泡沫具有良好的机械功能和绝热功能，通常状况下可耐温120℃经过改性或与其它隔热资料组合可耐温180℃。
The polyurethane directly buried insulation tube foam has good mechanical function and adiabatic function. Under normal conditions, it can withstand temperature 120 degrees, or be able to withstand temperature of 180 degrees when modified or combined with other insulation materials.
1.防腐层：维护外钢管防止腐蚀物腐蚀钢管，延伸钢管运用寿命。
1. Anti-corrosive coating: Maintain external steel pipe to prevent corrosion of steel pipe and extend service life of steel pipe.
2.外护钢管: 维护保温层免受地下水腐蚀，支撑任务管并能接受一定的内部荷载，保证任务管正常任务。
2. External protection steel pipe: Maintain insulation layer from groundwater corrosion, support task pipe and accept certain internal load, ensure the normal task of task pipe.
3.聚氨酯泡沫层: 保证介质温度，保证外护管外表坚持常温。
