摘要
分别从原材料、生产工艺、产品质量、投资、价格、信誉度和市场等７个方面，分析比较了螺旋缝埋弧焊管和直缝埋弧焊管的各自特点。提出要建设直缝埋弧焊管机组，应谨慎选择上马时机和生产线数量。
The features of spirally submerged arc welded pipes and longitudinally submerged arc welded pipes are compared according to the following seven aspects: raw material, productive technique, product quality, cost, price, reputation and market. If the longitudinally submerged arc welded pipe production lines were wanted to be built, the time and the number of the production lines should be selected carefully.
