Steel sleeve steel prefabricated buried steam insulation pipeline is an efficient insulation, anti-corrosion, and corrosion-resistant pipeline composed of inner working steel pipe, outer protective steel pipe, and intermediate insulation layer. The inner steel pipe adopts an organic silicon high-temperature resistant paint anti-corrosion coating, and the pipe mouth is sealed with a polyene film or three-layer PE cold winding tape, which can effectively prevent corrosion and extend the service life. The insulation layer is made of centrifugal glass wool and wrapped in multiple layers of stagger

钢套钢预制直埋蒸汽保温管道是一种高效保温、防腐、耐侵蚀的管道,由内工作钢管、外保护钢管和中间保温层组成。内钢管采用有机硅耐高温漆防腐涂层,管口采用多烯薄膜或三层PE冷缠胶带密封,可有效防止腐蚀和延长使用寿命。保温层采用离心玻璃棉,采用多层交错包裹,可有效减少热量损失。 

钢套钢预制直埋蒸汽保温管道的结构非常简单,主要由工作钢管、玻璃棉保温隔热层、铝箔反射层、不锈钢紧固钢带、滑动导向支架、空气保温层、外护钢管和外防腐层组成。工作钢管可以选择无缝钢管或螺旋焊接钢管,但无论选择哪种钢管,都应该保证其质量和尺寸精度。

 钢套钢预制直埋蒸汽保温管道的保温性能非常出色,但钢管外的钢套钢保温管和保温层之间有一层空气层。这是因为蒸汽管道温度较高,会导致保温层发生胀大,空气层可以保护作业管和外护管相对滑动时不破坏保温层。空气层使钢套钢蒸汽保温管构成了一个通腔,一旦有管道走漏或者漏气,蒸汽会顺着空气层从排潮管中排出,从而确定走漏的位置并及时进行修缮。
