Abstract
Способ ремонта штанг насосных (ШН), включающий радиационный контроль, очистку их поверхности от отложений парафина, соли и асфальтенов, визуальный и приборный контроль, обрезку головок и участков ШН с недопустимыми дефектами, высадку (изготовление) новых головок, термическую обработку, горячую правку, охлаждение, дробеструйную обработку тела ШН, механическую обработку головок штанг, отличающийся тем, что участки ШН с недопустимыми дефектами не обрезают, а им придают повышенные прочность и коррозионную стойкость наложением на дефектные участки обечаек, сопрягаемые поверхности которых заранее очищают до металлического блеска, наносят на эти поверхности клей с высокой адгезивной способностью, после чего обечайки сдавливают до плотного соприкосновения сопрягаемых поверхностей обечаек и ШН, а после определенной выдержки давление на обечайки снимают и создают условия для полимеризации клея.A method of repairing sucker rods (SH), including radiation monitoring, cleaning their surface from deposits of paraffin, salt and asphaltenes, visual and instrument control, cutting heads and sections of SH with unacceptable defects, planting (manufacturing) of new heads, heat treatment, hot dressing, cooling, bead-blasting of the body of the ШН, machining of the heads of the rods, characterized in that the sections of the ШН with unacceptable defects are not cut, and they are given increased strength and corrosion resistance by superimposing on defective ASTK shells, mating surfaces beforehand purified to metallic luster is applied onto the surface of adhesive with high adhesive ability, whereupon the sleeve is compressed to the dense contact between the mating surfaces of the shells and SHN, and after a certain holding pressure on the sleeve is removed and create conditions for polymerization of the glue.
