石油、天然气输送的双缝埋弧焊管及生产方法,应用于双缝埋弧焊管生产。特征是:采用宽度为钢管周长1/2的两块钢板,利用双面埋弧焊方法首先进行两块钢板沿纵向边拼接,然后采取常用的直缝埋弧焊钢管生产工艺进行钢管制作;另一 Oil and gas transmission double seam SAW pipe and production methods, used in double seam SAW pipe production. The features are as follows: Two steel plates with a width of 1/2 of the steel pipe are used, and the two steel plates are spliced ​​along the longitudinal edges by a double-sided submerged arc welding method firstly, and then steel pipes are produced by the common production process of the longitudinal seam submerged arc welded steel pipe; another
