DEVELOPMENT OF ELECTRIC WELD PIPES FOR LOWER/MEDIUM-PRESSURE BOILERS

Developing electric weld pipes for lower/medium-pressure boilers is important in expanding weld tube categories and optimizing steel tube product mix. Introduced in the paper are such aspects concerning the said boiler pipes as selection of material,major production equipment configuration and manufacturing process flow,etc., focusing on critical techniques like control of welding process parameters,removing of inner burs and heat treatment.
