防腐钢管改性石油沥青卷材缠绕机具

Wrapping Machine of Improved Petroleum Asphalt Roll Material for Steal Pipe Anti-corrosion

改性石油沥青卷材需在加热条件下缠绕才能粘结在管道表面，针对管道外防腐层大修施工中手工操作的不足，研制成功缠绕加热一体式专用机具，该机具也可作为冷缠绕机用于自粘胶带的施工作业。

Improved petroleum asphalt roll material can be stick to the surface of pipe under the heating condition. An exclusive tool with wrapping and heating functions has been successfully developed to solve the disadvantage in manual operation for outside anti - corrosion coating of pipe. It can be used for construction of self stick tape as a non - heating wrapping tool.
