On July 15th, the first 18 -meter -long spiral arc welded pipe of the first 18 -meter -long spiral arc welding pipe of the National Pipeline Network -Hekou Natural Gas Liaison Pipeline Project was smoothly offline at PetroChina Polyshun (Qinhuangdao) Steel Pipe Co., Ltd. The first application in the field of oil and gas transportation pipe.

It is understood that the length of the steel pipe used in the current commonly used oil and gas transportation pipelines is generally about 13 meters. During the construction of pipeline construction, compared with the traditional 13 -meter steel pipe, if the 18 -meter -long steel pipe is used, the number of rings welding channels will be reduced by 28%. 30%, greatly reducing project construction costs.

"The company's spiral pre -welding production line adopted a advanced design of 18.3 meters steel pipes at the beginning of construction. With the improvement of the development and transportation requirements of pipelines, the steel pipes will be more suitable for market demand in the next 18 meters." CNPC Baoshun (CNPC (CNPC (CNPC (CNPC (CNPC (CNPC (CNPC (CNPC (CNPC (Pokémon Shunshun (CNPC (CNPC (CNPC (Pokémon (Pokémon (Pokémon (Pokémon (CNTO秦皇岛）钢管有限公司总经理吴在盛介绍，目前企业正在建设一条新能源管材生产线，加上已有的直缝焊管、螺旋焊管、钢管防腐、热煨弯管生产线，新生产线投产后公司的装备制造和The integrated advantage will be more prominent. In the next step, the company will continue to be better in the development of new product research and development, equipment informationization and intelligence, and "manufacturing+service", and strive to make more contributions to the development of the country in the development of traditional energy and new energy pipeline transportation.

The National Management Network Ancient Wave -Hekou Natural Gas Liaison Pipeline Project is an important project for the national gas supply network of the country. The project starts from Gu Langwan Station, and Houkou Station is the end point. From north to south, it passes Gulang County, Tianzhu County, Jingtai County, Baiyin City, Yongdeng County and Xigu District of Xigu. 10 MPa, designed an annual output of 5.08 billion cubic meters.项目建成后，河口站将成为联络兰银线、涩宁兰双线及新建古河线的枢纽，实现多条管线的灵活供气和调气，使兰州及周边地区形成“多气源”“多The new supply pattern of channels is of great significance to solve the problem of gas supply balance between three provinces in western my country.
