Abide by the production safety law! Be the first responsible person! ----------------------------------------------- The last ten years have been an era of great development for China's chemical industry. The emergence of many new processes, new products, and new equipment has also been a great development for my country's chemical equipment, which has also promoted the rapid development of the petrochemical industry. Here we have collected and sorted out some of the achievements and breakthroughs made by my country's equipment companies in the large-scale and localization of equipment. Welcome everyone to share, discuss, cheer for Made in China, and cheer for chemical equipment! ------------------------------------------------------ Huayou Steel Pipe Company started the trial production of X80 steel grade Φ1219×22mm spiral welded steel pipes in 2013. It completed the single-furnace trial production in September 2013 and the small batch trial production in 2014. It passed the new product appraisal jointly organized by the Science and Technology Management Department of China National Petroleum Corporation and the Development and Science and Technology Environmental Protection Department of China Iron and Steel Industry Association. ； In November 2016, mass production of the Zhongjing Line and Shaanxi-Beijing Line 4 natural gas pipeline projects officially started. X80 steel grade Φ1219×22mm spiral welded steel pipe is the prerequisite and guarantee for the use of 22mm specification spiral welded pipes in secondary areas. It is also a high-end transportation equipment developed to meet the future construction needs of long-distance natural gas pipelines. It is mainly used in the construction of long-distance and high-pressure transmission pipelines for oil and natural gas. It has the characteristics of high transmission efficiency, low cost, high strength and toughness, strong weldability, stable performance, safety and reliability, and long service life. The performance indicators of the products produced by Huayou Steel Pipe Company have reached the international leading level. With the acceleration of the construction of projects such as the West Fourth Line and the West Fifth Line, the use of spiral welded pipes for steel pipes with a wall thickness of 22mm in Class II areas in my country will be further promoted, and the product market prospects are broad.
