Claims (2)

1. Способ соединения эмалированных труб с кислым типом покрытия, включающий одностороннюю сварку корневого шва, отличающийся тем, что в процессе сварки используют высоколегированные электроды с покрытием основного типа с образованием на внутренней поверхности шва коррозионностойкого покрытия сплавлением шлака с околошовной эмалью.1. The method of connecting enameled pipes with an acid type of coating, including one-sided welding of the root seam, characterized in that the welding process uses highly alloyed electrodes with a coating of the main type with the formation on the inner surface of the weld of a corrosion-resistant coating by alloying slag with heat-treated enamel. 2. Способ по п.1, отличающийся тем, что осуществляют сварку труб с притуплением 1,5-2,0 мм в корне стыка и поддерживают погонную энергию сварки 600-700 Дж/см. 2. The method according to claim 1, characterized in that the pipes are welded with a blunting of 1.5-2.0 mm at the root of the joint and the linear energy of welding is maintained at 600-700 J / cm.
