Description
技术领域technical field
本发明属于输油管线内防腐技术领域，具体涉及一种适用于60毫米直径输油管道的环氧粉末涂料内补口装置，用于对外径为60毫米钢管焊缝进行内防腐。The invention belongs to the technical field of internal anti-corrosion of oil pipelines, and particularly relates to an epoxy powder coating internal filling device suitable for oil pipelines with a diameter of 60 mm, which is used for internal anti-corrosion of welded seams of steel pipes with an outer diameter of 60 mm.
背景技术Background technique
国内大部分油田的单井输油管道采用直径60毫米的无缝钢管，单根钢管的内外防腐在防腐厂已经技术成熟，由于60毫米钢管内部尺寸很小，针对焊缝的内防腐补口一直未开发出可靠技术，使得单根防腐预制钢管不能得到大面积推广。但是，恰恰是60毫米管道的腐蚀穿孔，造成漏油事故频发，影响了油田的正常生产。Most of the single-well oil pipelines in domestic oilfields use seamless steel pipes with a diameter of 60 mm. The internal and external anti-corrosion of a single steel pipe has been matured in the anti-corrosion plant. Due to the small internal size of the 60 mm steel pipe, the internal anti-corrosion repair for the weld has not been carried out. Reliable technology has been developed, so that a single anti-corrosion prefabricated steel pipe cannot be widely promoted. However, it is precisely the corrosion and perforation of the 60mm pipeline that causes frequent oil spills and affects the normal production of the oilfield.
