南阳直埋式保温管 Directly buried insulation pipe is a kind of insulation pipe which is directly buried in the ground and is used to transport hot water. It has the characteristics of low heat loss, good thermal insulation effect and long service life. It is widely used in oil, chemical industry, hot water heating and other industries. The insulation pipe is made of steel pipe and polyurethane foam insulation layer. The steel pipe is made of seamless steel pipe or spiral welded pipe. The insulation layer is made of polyurethane foam with excellent performance. The insulation layer is formed by one-time foaming and molding. The insulation layer has good compressive strength and low thermal conductivity. It has good thermal insulation effect and can reduce energy consumption. 直埋式保温管是一种直接埋入地下的保温管，用于输送热水，具有低热损失、保温效果好、使用寿命长等特点，广泛应用于石油、化工、热水供暖等行业。保温管由钢管和聚氨酯泡沫保温层构成，钢管采用无缝钢管或螺旋焊管制成，保温层采用具有优异性能的聚氨酯泡沫制成，保温层采用一次发泡成型，具有良好的抗压强度和低的热传导率，具有良好的保温效果，能够减少能耗。 |
