低中压锅炉用电焊钢管的研制

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

开发低中压锅炉用电焊钢管是扩大焊管品种和调整钢管产品结构的重要内容。介绍了该产品的原材料选用、主要生产设备配置及生产工艺流程等。重点对焊接工艺参数控制、内毛刺去除及热处理等关键技术进行了讨论。

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.
