Sliding Structure in Steam Insulation Pipe
直埋蒸汽保温管“内滑动”构造特点:
Structural characteristics of "internal sliding" of directly buried steam insulation pipe:
1)内钢管经过抛丸除锈到达Sa2.5级(近白级)后,涂刷无机富锋底漆,避免施工时期进入保温层的水汽对内钢管的腐蚀。
1) After shot peening and rust removal, the inner steel pipe reaches Sa2.5 (near white grade), and is coated with inorganic rich front primer to avoid the corrosion of the inner steel pipe caused by water vapor entering the insulation layer during the construction period.
2)管道受热收缩发作位移,内钢管里面包扎的一层减阻层,可以增加内钢管在保温层上的挪动的阻力。
2) Pipeline shrinkage occurs displacement when heated, and a layer of drag reduction layer wrapped inside the inner steel pipe can increase the resistance of the inner steel pipe to move on the insulation layer.
3)保温资料内层采用微孔硅酸钙错缝包扎在内钢管上,并在缝隙填充耐低温高弹保温资料,无效增加了热损失。
3) Microporous calcium silicate is used to wrap the inner layer of heat preservation material in staggered seams on the inner steel pipe and fill the gap with low temperature and high elasticity heat preservation material. Invalidity increases the heat loss.

4)外层保温选用聚氨酯保温资料,应用聚氨酯优秀的保温功能,控制外防护层外表温度低于50℃,维护外防护层,添加管道全体寿命。
4) The polyurethane insulation material is selected for the outer layer insulation. The excellent insulation function of polyurethane is applied to control the outer temperature of the outer protective layer below 50 C, maintain the outer protective layer and add the whole life of the pipeline.
5)两层保温资料之间参加“辖射反射层”,控制了热量的福射散热损失,使直埋蒸汽保温管愈加经济合理。
5) Participate in the "reflective layer" between the two layers of thermal insulation data to control the heat radiation loss and make the directly buried steam insulation pipe more economical and reasonable.
6)蒸汽保温管外防护层可选用多种方式,包括玻璃钢、套管外加防腐层等方式,防腐层方式多样,无效维护钢套管不受地下水腐蚀。
6) There are many ways to choose the outer protective layer of steam insulating pipe, including FRP, casing and anti-corrosion layer. The anti-corrosion layer is various, and the steel casing can not be corroded by groundwater if it is not effectively maintained.
