Description

Известен способ производства сварных труб с предварительной обдувкой нагретых кромок трубной заготовки окислительной средой, преимущественно воздухом или обогащенным кислородом воздухом.A known method for the production of welded pipes with pre-blowing the heated edges of the billet with an oxidizing medium, mainly air or oxygen-enriched air.

Предлагаемый способ производства сварных труб отличаетс  тем, что окислительную среду подогревают до температуры 4ОО°С и выще, это повышает качество сварного шва и производительность.The proposed method for producing welded pipes is characterized in that the oxidizing medium is heated to a temperature of 4 ° C and higher, which improves the quality of the weld and the productivity.

Воздух может быть нагрет либо в рекуператорах за счет тепла отход щих продуктов горени , либо в отдельном подогревателе (электрическом и др.).The air can be heated either in recuperators due to the heat of the waste combustion products, or in a separate heater (electric, etc.).
