| 我国地域辽阔，很多地区在冬季进行天然气管道内减阻涂装施工是常事，如何保证冬季施工质量是面临的课题之一。分析了天然气管道内涂减阻涂料冬季施工的影响因素为：钢管表面温度过低；涂料的黏度大幅上升。针对这些影响因素，提出了对钢管预热、保证施工工艺连续来获得适宜的喷涂温度；通过加装电伴热带对内减阻涂料加热并结合搅拌的措施，来获得适宜的涂料黏度。应用结果表明，冬季施工采取适当的措施成功避免了涂层缺陷的出现，保证了施工质量。 |
| 英文摘要: |
| Our country is a vast land, and it's very common to conduct gas pipeline inner resistance-inducing coating construction in winter in many areas, so how to ensure the winter construction quality is one of the topics were facing today. The influential factors of gas pipeline inner resistance-inducing coating construction: the dramatically low temperature of the steel pipe s surface and the big increase of the coatings viscosity were analyzed. In view of these influential factors, the proper gushing temperature could be obtained by heating the steel pipe beforehand and ensuring the construction techniques continuously and the appropriate viscosity of the coating was gained through installing the electric heating belt to heat the inner resistance-inducing coating and stimng it. The application results show that the winter construction measures avoid the emergence of the coatings defects successfully and guarantee the construction quality. |
