管母的单根长度有限,在施工中要将几根管母焊接起来,焊接的数量较多。焊接后的接口需要冷却、管母的移动又需要较多的人力。在新工艺中,采取滚动滑轮滚动管母,只需要在较短的时间内就可以完成焊接后管母的移动,不仅可以减少接口的冷却时间,也减少了施工人员的投入,焊接接口处因不受张力的作用,有效地保证了焊接强度,对管母的焊接质量不会造成任何破坏,最重要的是节省了施工成本。
The length of a single root tube is limited, in the construction of several pipe joints to be welded together, the number of welding more. The interface after welding needs to be cooled, and the movement of the tube holder requires more manpower. In the new process, the use of rolling wheel rolling tube mother, only in a short period of time can be completed after the welding tube mother tube movement, not only can reduce the interface cooling time, but also reduce the input of construction workers, welding interface Not the role of tension, to effectively ensure the welding strength, the quality of the mother of the welding will not cause any damage, the most important thing is to save construction costs.
