Manufacturing Internal and External Spiral Welding Pipe status and development trend of spiral seam submerged arc welding steel pipe at home and abroad



Abstract: the rapid Internal and External Spiral Welding Pipe development of oil and gas pipelines makes the application of spiral submerged arc welding steel pipe more and more widely. Up to now, spiral submerged arc welding steel pipe has gradually become an integral part of China's oil and natural gas pipeline construction, with a more and more important role. Based on this, in order to better grasp the current situation of the development of Internal and External Spiral Welding Pipe spiral submerged arc welding of steel pipe manufacturing technology and the direction, to make it Internal and External Spiral Welding Pipe better for spiral submerged arc welding steel pipe manufacturing industry in China as well as oil and gas pipeline construction services, articles for Internal and External Spiral Welding Pipe spiral submerged arc welding steel pipe manufacturing at home and abroad present situation and development Internal and External Spiral Welding Pipe direction are studied, pointed out that the spiral submerged arc welding steel pipe manufacturing technology present situation and development trends. 



With the continuous expansion of China's Internal and External Spiral Welding Pipe oil and natural gas pipeline construction scale, especially the completion of the launching Chengdu-Chongqing product pipeline, the Shibu-England natural gas pipeline, the Internal and External Spiral Welding Pipe  natural gas pipeline and other pipelines, as well as the continuous construction and promotion of China's west-east natural gas  Internal and External Spiral Welding Pipe transmission project, the study on pipeline steel in China has been effectively promoted [1-2]. The current manufacturing standards for petroleum and natural gas transportation steel pipes are the national standard (GB/T9711.1 and GB/T9711.2) and the American petroleum institute standard (API Spec 5L). As an important part of the Internal and External Spiral Welding Pipe oil and natural gas pipelines, spiral seam submerged arc welding steel pipe has been widely used and studied .


But the equipment configuration and process layout are very uneven, and there is still a certain process gap from developed countries. In order to have an accurate understanding of the current manufacturing status of Internal and External Spiral Welding Pipe spiral welded arc-welded steel tubes and the technological gap between China and foreign countries, this paper analyzes and summarizes the relevant literature on the manufacturing technology of Internal and External Spiral Welding Pipe spiral welded arc-welded steel tubes, and studies the development trend and direction of the manufacturing technology of Internal and External Spiral Welding Pipe spiral welded arc-welded steel tubes. The research in this paper has an important reference value for the development of manufacturing technology of spiral submerged arc welding steel pipe in China.
