First, the status quo of the steel pipe industry

According to the relevant data of the National Bureau of Statistics, according to incomplete statistics, as of 2019, our country has about 3,000 sets of various types of welded pipe units, with a total production capacity of about 90 million tons. Among them, there are about 36 sets of longitudinal submerged arc pipe production lines (including UOE, JCOE, JCO, JCO), with a production capacity of about 7.5 million tons; 32 sets of high-frequency longitudinal welded steel pipe (ERW/HFW) production lines with φ426mm, □400mm (rectangular pipe) and above specifications, with a production capacity of about 6.91 million tons; There are more than 80 sets of φ219-406mm high-frequency longitudinal welded steel pipe production lines, with a production capacity of about 10 million tons; There are about 420 sets of φ114-φ180mm high-frequency longitudinal welded steel pipe production lines, with a production capacity of about 20 million tons; There are about 2,000 sets of high-frequency longitudinal welded pipe production lines of φ89mm and below, with a production capacity of about 16 million tons; There are about 400 sets of spiral seam submerged arc welded steel pipe production lines (9 sets of pre-finished welding units), with a production capacity of about 10 million tons.
In 2020, our country's steel pipe output was 89.54 million tons, of which the output of welded pipes was 61.67 million tons and the output of seamless pipes was 27.87 million tons. In the process of steel pipe production growth, steel pipe specifications, variety, quality and service have also made significant progress, in 2004 our country's steel pipe output has ranked first in the world, after 2012, our country's steel pipe output has accounted for more than 50% of the world's total steel pipe output, especially a number of high-end steel pipe products have broken the foreign monopoly and technical blockade, steel pipe product self-sufficiency rate reached more than 99%, which strongly supported the rapid development of the national economy and the transformation and development of steel pipe downstream industry. Over the past 50 years, the cumulative output of steel pipes in our country has reached more than 1.1 billion tons, of which the output of welded pipes has reached more than 700 million tons, and the output of seamless steel pipes has reached more than 400 million tons.
After ten years of development (2010-2020), our country's steel pipe industry has been continuously optimized and improved in terms of product structure, quality level, technical equipment, etc., providing an important raw material guarantee for the rapid development of the national economy.
The unmanned steel pipe production line is the direction. In line with this basic trend of development, we must move towards growth that is efficient, beneficial to people's livelihood and quality, and achieve high-quality development in order to truly become a high-income country. The key to the development of steel pipe enterprises lies in quality, not in high-end products, and the key to quality lies in the consistency of quality. The consistency of mass production of steel pipe performance and product appearance and other indicators is the embodiment of the vitality of steel pipe production enterprises in the future.
Our country's welded pipe manufacturing industry is in a period of steady development from 1978 to 2001, from 2002 to 2015 in a period of rapid development, and after 2016 it has steadily entered a period of structural adjustment, which is also the achievements of China's steel pipe industry after implementing policies such as eliminating backward production capacity, structural adjustment, making up for shortcomings, and improving quality and efficiency, indicating that China's steel pipe manufacturing industry has promoted supply-side structural reform and steadily improved transformation and upgrading.
Recently, the technology, technology and equipment of our country's steel pipe manufacturing industry have reached the world-class level. For the industry's healthy and tamping day-to-day tour of the country, the steel pipe manufacturing model is complete, the technology is advanced, and the specifications, varieties, quality, and service steps are improved. to meet market demand; The competitiveness in the international market is obvious
