钻杆管体在经过热处理工序时,会产生大量的氧化皮,氧化皮附着在钢管表面,造成管体的表面质量明显降低,由于氧化皮的覆盖,管体表面的某些缺陷得以隐藏,管体缺陷的检测准确率大大降低。同时在除鳞作业过程中,高压泵一直高速运转,消耗大量的电能,除鳞时消耗大量的自来水,增加了公司的生产成本。
Drill pipe body after heat treatment process, will produce a lot of oxide scale, the scale attached to the steel surface, resulting in a significant reduction in the surface quality of the pipe body, due to the oxide coating, the surface of the tube to hide some of the defects, the tube Body defect detection accuracy greatly reduced. At the same time in the descaling operation process, the high-pressure pump has been running at high speed, consume a lot of electricity, desalination consume large amounts of tap water, an increase of the company’s production costs.
