产品介绍

预制发泡聚氨酯保温管

预制聚氨酯保温管保温结构依据滑动方式不同分为:内滑动式与外滑动式1、内滑动式:保温结构由工作钢管、硅酸铝、减阻层、微孔硅酸钙、隔热层、不锈钢紧固钢带、铝箔反射层、聚氨酯保温层、外套钢管、外防腐层组成2、外滑动式:保温结构由工作钢管、玻璃棉保温隔热层、铝箔反射层、不锈钢紧固带、滑动导向支架、空气保温层、外护钢管、外防腐层组成钢套钢保温管结构图三、结构机理1.防腐层:保护外钢管避免腐蚀物腐蚀钢管,延长钢管使用寿命2.外护钢管:保护保温层免受地下水侵蚀,支撑工作管并能承受一定的外部荷载,保证工作管正常工作3.聚氨酯泡沫层:保证介质温度,保证外护管表面保持常温4.阻隔、反射层:保证有机钢套钢蒸汽保温管是由外护钢管加钢管防腐、聚氨酯泡沫保温层及内工作钢管组合而成。钢套钢蒸气复合保温管适用于输送2.5MPa、350摄氏度以下的蒸汽或其它介质,该产品用钢管做外防护层,具有强度高,不易损坏,施工检修简便,使用寿命长的优点。
