| Abstract: |
| 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. |
