Cold drawn tubes will still be the first choice for construction and manufacturing industries. In addition, some trends in steelmaking technology and the use of cold-drawn pipes will also affect the demand for cold-drawn pipes. "Collaborative design" and "process innovation" are expected to be the key drivers of these trends. On the demand side, the construction of power plants (including onshore and offshore wind farms), energy transport, housing and transportation sectors will provide opportunities for innovative cold-drawn pipe products. Increasing the added value of cold-drawn pipe products (including pipes) is one of the ways for cold-drawn pipe manufacturers to enhance their competitiveness and make them stand out from competitors. However, a recent study shows that high value-added cold-drawn products account for only a limited part of the demand for cold-drawn pipes due to intense competition in the cold-drawn industry. The production of these high value-added cold-drawn pipes requires a high-cost Cold-drawn Tube Rolling Process and a large amount of research and development funds.
Precision cold drawn pipe exports are increasing and international competitiveness is also improving. However, most of them are concentrated in the middle and low-grade fields. The technology level of precision cold drawing is low, and the added value is low. Some high-precision cold drawing pipes still depend on imports. Therefore, China's precision cold-drawn pipe manufacturing industry should strengthen integration in its own field, there is no need for excessive competition, the division of labor and cooperation in technological development, the relevant industries and enterprises should take a long-term view, concentrate on new technology and new process research, and gradually form a division of labor, cooperation, multi-field, all-round. The research and development pattern has introduced the precision cold drawn tube products with independent intellectual property rights. The development of precision cold drawing pipe and other industries can be described by lip and tooth dependence, so the overall level of cold drawing pipe is closely related to the development of related industries.
Through practice, it is found that deformation and leakage are one of the common problems of stainless steel cold drawing machine. There are several ways to solve these problems. Firstly, the method of lapping and scraping the joint surface is adopted to leveling the joint surface between cold drawing machine and equipment and avoid the adverse consequences caused by deformation. Secondly, local repair welding is also a feasible method, as long as the appropriate electrode is selected to smooth the groove marks, and with flat or flat ruler lapping marks, so that lapping weld beads and joint surface in the same plane. Preheat the stainless steel quilting tube before welding, then carry out segmented backwelding or skip welding at room temperature until completion. In fact, this problem also reminds us that we must be careful when choosing the sealing material of stainless steel cold-drawn, to ensure that its quality and performance can meet the requirements of pipe tightness. The development of cold drawing machine industry in recent years has mainly benefited from the support of the state's export tax rebate policy. A large number of domestic output capacity is oriented to the international market. At this time, everyone can peacefully coexist with each other. After 2007, the drawbacks of excess capacity of domestic derivative tubes have been highlighted and the export side has been suppressed by the policy. The domestic market has become a battleground for many manufacturers.
At the present stage, the whole cold-drawn pipe market has experienced an inevitable rebound after an excessive drop, and the earthquake in Japan has made the market speculation, but the earthquake in Japan seems to be only a small probability event, and the impact on China's real economy is temporarily equal to zero, the recovery of market demand is true. Positive motivation. With the improvement of demand, the stock market has also been digested in the previous period of time, driven by the rise of the leading market in Quanzhou market for two consecutive days to raise prices. However, unlike previous increases, the Cold-drawn Tube price rises appear to be more cautious, the extent is not large, because the price increases must also be concerned about whether the increase in demand can keep up. At present, the market is also entering the good fortune of the prosperous Asian market. From the current market point of view, it is estimated that there are two possible performances of the market in the future, one is that the market is rapidly rising, but may not be solid. Or for the steady growth of the market and enter the normal price track. It is estimated that the price of cold drawn square tubes will increase in the coming week.
