保温钢管有什么选购技巧
保温钢管有什么选购技巧
What are the skills of selecting and purchasing insulating steel pipes
保温钢管挑选技巧一：高温预制直埋保温管是一种保温性能好，加安全 可靠，工程造价低的直埋预制保温管。有效的解决了城镇集中供热中130℃-600℃高温输热用预制直埋保温管的保温、滑动润滑和 裸露管端的防水问题。高温预制直埋保温管不仅具有传统地沟和架空敷设管道难以比拟的先进技术、实用性能，而且还具有显著的 社会效益和经济效益，也是供热节能的有力措施。
Selection skill of insulating steel pipe: high temperature prefabricated directly buried insulating pipe is a kind of directly buried prefabricated insulating pipe with good thermal insulation performance, safety and reliability, and low cost. The problems of heat preservation, sliding lubrication and waterproofing of bare pipe ends of prefabricated directly buried insulating pipes for heat transfer at 130 - 600 C in urban central heating are effectively solved. The high temperature prefabricated directly buried insulating pipe not only has the advanced technology and practical performance that traditional trench and overhead pipeline laying can not match, but also has remarkable social and economic benefits. It is also a powerful measure of heating energy saving.
保温钢管挑选技巧二：由于聚氨酯硬质泡沫保温层紧密地粘结在钢管外皮，隔绝了空气和水的渗入，能起到良好的防腐作用。同时它的发泡孔都是闭合的，吸水性很小。高密度聚乙烯外壳、玻璃钢外壳均具有良好的防腐、绝缘和机械性能。因此，工作钢管外皮很难受到外界空气和水的侵蚀。
Two tips for insulating steel pipes: the polyurethane rigid foam insulation layer is tightly bonded to the outer skin of the steel pipe, and the infiltration of air and water can be isolated. At the same time, its foaming holes are closed and its water absorption is very small. High density polyethylene shell and FRP shell have good anti-corrosion, insulation and mechanical properties. Therefore, the outer skin of the working steel pipe is very difficult to be eroded by the outside air and water.
