Development Trend of Longitudinal Welded Pipe Unit
Release time:
2018-12-06 11:52
To analyze the market situation of longitudinal welded pipe units, we must first analyze the Chinese steel pipe industry. China's domestic steel pipe industry has been developing rapidly for nearly ten years. Starting from 2010, China's domestic steel pipe industry has occupied more than 50% of the world market in 2010, with welded steel pipes accounting for more than 45%. According to this point of view, China is already a major steel pipe producer.

Starting from 2010, China's domestic steel pipe industry has occupied more than 50% of the world market in 2010, with welded steel pipes accounting for more than 45%. According to this point of view, China is already a major steel pipe producer. From this aspect to analyze the future market and industry development situation of welded pipe unit, it is easy to see,
In a sense, China is already a big producer of welded pipe units, and the current state is sustained and rapid growth!! According to the statistics of relevant departments, the steel pipe industry has reached the level of tens of millions of tons, but in the long run, in the next few years, the global economy will maintain a relatively slow growth trend, so at the same time as an overall economic level slows down, the price of welded pipe units will become more and more normal. Relevant experts discussed how to realize the transformation from steel pipe power to steel pipe power in China, and reached a consensus. They believe that China's steel pipe industry should implement and implement the scientific concept of development, adhere to the "three priorities" and "one fundamental change", that is, focus on increasing high-tech and high value-added products and improving quality, and should not unilaterally pursue quantitative expansion; focus on improving product concentration and strengthening the reorganization and transformation of existing enterprises, and should not rely solely on laying new stalls and new projects. The emphasis is on reducing consumption and improving the competitiveness of enterprises and products, adhere to the new road of industrialization; realize the fundamental transformation of China's steel pipe industry from large to strong, and strive to build a steel pipe power with international competitiveness.
Experts pointed out that in the past five years, my country's steel pipe industry has achieved rapid development simultaneously with my country's steel industry. The output in 2004 has reached 21.23 million tons, and it is expected to reach 24.5 million tons in 2005, accounting for more than 1/4 of the global steel pipe output. At present, China's steel pipe production capacity has exceeded market demand, and has become one of the world's largest steel pipe exporters. The pursuit of quantitative development to meet market demand has become history, and taking the road of new industrialization development and realizing circular economy has become an important work content of China's steel pipe industry. Maintaining a reasonable scale and moderate growth rate is an important prerequisite for the healthy development of China's steel pipe industry. At present, the capacity of China's steel pipe industry has been built, under construction and proposed to be built has exceeded the demand of the domestic market, and low-level repeated construction must be strictly controlled. For this reason, the relevant experts put forward some specific suggestions on the transformation of China's steel pipe power from a big country to a steel pipe power.
Suggestions on the development of seamless steel pipe
The continuous rolling pipe unit is the most advanced and largest hot-rolled seamless steel pipe unit introduced after the 1980 s in China. The annual output of a set of units can reach 800000~1 million tons, but its investment is very huge. The number and time required to replace the mold in the production process are more and longer than other units. It is the best unit to adapt to less specifications and mass production. It is best to have multiple sets of such units in a group or company in order to divide production, so as to achieve the effects of fewer production specifications, large batches, high output, low consumption, high efficiency, low cost, and strong competitiveness on a set of units. Now, on the basis of our own research and development in the early stage, our country has been able to independently develop, design and manufacture this modern advanced steel pipe production equipment, so as to realize the localization of this major equipment.
Precision pipe rolling set is the only machine in China that only introduces software technology to develop. The whole set of pipe rolling set is jointly designed and manufactured with the United States. Disc pipe rolling set was independently developed on the basis of diesel pipe rolling mill independently developed by China, which absorbs the core technology of precision pipe rolling mill. Now it has been widely used in China. This kind of unit has low investment, high precision, short process, only needs one heating, simple replacement of product specifications, and short time, but it is not a high-capacity unit, but a variety of rolling mills. In addition, there are automatic pipe rolling units, three-roll pipe rolling units, pipe jacking units, and periodic pipe rolling units.
In short, all kinds of pipe rolling units have their own advantages and should form their own market according to their respective regions and product positioning, continuously improve and improve their varieties and quality, and make great efforts to reduce energy consumption and material consumption to form the advantage of low cost. A number of high-cost, poor-quality pipe rolling units will be naturally eliminated with the development of the market economy, especially the situation of oversupply. Steel pipe enterprises that have not yet implemented stable pipe billet resources should take the establishment of long-term strategic alliances or partnerships with metallurgical enterprises as an important measure to ensure the stability of raw material supply and production, improve product quality, and adjust product structure, otherwise they will be eliminated.
