Abstract

Изобретение относитс  к защите труб от коррозии. Цель изобретени  - повышение качества покрыти  за счет улучшени  защитных свойств концевых участков свариваем.1х труб. После, очистки, нагрева и нанесени  ме.тал- локерамического самофпюсующегос  ма- |териала провод т его оплавление, Раз- ;м гченньш сплав уплотн ют обкаткой . на длину термического воздействи  сварки.This invention relates to the protection of pipes against corrosion. The purpose of the invention is to improve the quality of the coating due to the improvement of the protective properties of the end sections of welded 1x pipes. After cleaning, heating and applying a me- tallocaric self-fabricating material, it is reflowed, expanded, and the soft alloy is compacted by running. on the length of the thermal effects of welding.

Цель дополнительного изобретени  - i повышение качества покрыти  за счет улучшени  защитных свойств концевых участков cвapивae G,Ix труб.The purpose of the additional invention is to improve the quality of the coating by improving the protective properties of the end sections of the C, G, Ix tubes.

Внутреннюю поверхность трубы очищают одним из известных способов. После предварительного нагрева на внутреннюю и торцовую поверхности конца трубы нанос т металлокерами- ческий самофлюсующийс  матери-ал, например сплав dr- CP, на длину, превышающую зону термического воздействи  сварки. Затем провод т термообработку покрыти.  оплавлением с последую- The inner surface of the pipe is cleaned with one of the known methods. After preheating, the metal-ceramic self-fluxing material, such as dr-CP alloy, is applied to the inner and end surfaces of the pipe end for a length exceeding the heat-affected zone of welding. Then the coating is heat treated. reflow with subsequent
