Application and Development Prospect of X80 Pipeline Steel
In the fierce market competition, all oil companies in the world are constantly looking for ways to reduce costs and improve efficiency.
In the investment of pipeline construction projects, the cost of steel pipe accounts for about 40%. The use of X80 pipeline steel can reduce the wall thickness, thereby reducing the investment cost of the project. In addition, in the case of high-pressure transportation, the use of X80 pipeline steel can also significantly reduce the operating cost, which is the main reason is that the higher the grade of natural gas pipeline steel, the higher the transmission pressure. The continuous improvement of the level of technical equipment in the metallurgical industry provides technical support for meeting the strength level and delivery pressure of natural gas pipeline steel. Using X80 pipeline steel instead of X70 pipeline steel in the same pipeline construction project can save 8%-12% of the pipe material cost and 3%-12% of the total project cost. The economic benefits brought by X80 pipeline steel are very obvious.
At present, the smelting, rolling and welding technology of X80 pipeline steel is very mature, whether it is weld quality, strength matching or production cost, X80 pipeline steel can achieve satisfactory results.
