完善我国油气管道钢管制管体系的几个问题

油、气管道输送在我国已有一定基础，与先进工艺国家相比，还存在相当大的差距，油，气管道用钢管是管道建设的基础，钢管的质量决定于钢板（板卷）与制管的质量。文章论述我国即将进入建设长距离，大口径，高压力油气输送管道的今天，必须要解决国产管线钢，钢板生产和生产直缝双面埋焊钢管的问题。论述了直缝埋弧焊钢管与高质量螺旋缝钢管在我国油、气管道建设中的各自作用和地位，提高了发展管线钢生产和建设直缝埋弧焊机组的类型

Improving the system of manufacturing the steel pipe used in oil and gas pipeline

he foundation has been made on oil and gas transmission pipeline in our country. But comparing with other advanced countries, there is a wide gap between them and us. The steel pipe used in oil and gas transmission pipeline is the foundation of pipeline construction. The quality of steel pipes depends on the quality of the steel plate (plate roll) and manufacturing pipes. This paper has been described that because today our country will construct the long-distance, large-diameter and high-pressure oil and gas transmission pipeline, we must solve the problem of the domestic pipeline steel, steel plate production and longitudinally double-face submerged arc welded pipe production. The status and function of the longitudinally double-face submerged arc welded pipe and the high quality spirally submerged arc welded pipe in the oil and gas pipeline construction of our country are described respectively. The suggestions of developing pipeline steel production and setting up the mill type, quantity and local distribution when constructing the longitudinally submerged arc welded pipe production line are put forward.
