Precision steel tube is a kind of very hard and wear resistant thick-walled seamless tube, has a widespread application in the engineering construction, popularization of precision steel tube manufacturer today to give you the precision of the pressure steel pipe manufacture, forging, welding, welding, heat treatment production difficulty.
Precision steel tube is a kind of very good compression resistance and abrasion resistance of thick wall seamless tube, and is not easy to rust, so we are widely used to daily daily life. Guys bike hob for Cold Drawn Steel Tubes example is with orthodox thick-walled seamless tube of precision steel tube, because that can ensure that the bicycle clothing fashion, can also convenient bicycle compressive ability, normal orthodox thick-walled seamless tube precision steel pipes are also used in natural gas pipeline, the daily tasks for orthodox thick-walled seamless tube precision tube to do it.
Precision steel pipe production situation, the pressure on production, forging, welding, welding, heat treatment method, milling the whole process of manufacturing and other technology, precision steel tube goods is likely to lead to internal stress. The vast majority of cases, at the end of the production process the whole process, the metal part of the internal structure will be stored thermal stress. Internal stress can lead to commodity product crack, deformation or specifications change, the thermal stress also increase nonspecific metal analytical chemistry, especially in under the action of a residual tensile stress is easy to cause the intercrystalline corrosion cracking. Therefore, the thermal stress will harm performance parameters of precision steel tube workpiece premature failure or cause commodity products. To stress field heat treatment, precision steel tube is a kind of very hard and wear resistant thick-walled seamless tube, has a widespread application in the engineering Cold Drawn Tubes construction, we attach great importance to.
Precision steel pipe specification looks more delicate, but also orthodox thick-walled seamless tube is strict according to product standards production, so it is relatively good precision steel tube processing factory.
Precision cold drawn steel exports continued to rise, the continuation of the previous good picks up momentum, published the study sinolink securities analyst pointed out that as the concentrated period, the end of Europe and the United States before the summer recess orders, and downstream enterprises in the asia-pacific region to fill inventory end, domestic production enterprises in export orders may begin to decline, after the late precision cold drawn steel export quantity more likely to fall.
To improve and implement policy measures to promote the iron and steel enterprises mergers and reorganization. In the project examination and approval, land supply, loans, credit, capital market financing and arrangement of state-owned capital operation budget expenditure, etc., to strengthen the support of enterprise merger and reorganization. For state-owned iron and steel enterprises for periodic business performance decline and rising debt restructuring, etc., regulators to determine annual appraisal of state-owned assets and make corresponding adjustment in the term objective.
Iron and steel enterprises mergers and reorganization to take standardized operation in accordance with the law, protecting the legal rights and interests of investor and worker, protect the legitimate creditor's rights security, financial institutions to precision welded tubes prevent loss of state-owned assets, maintenance enterprise and social stability. Precision cold drawn steel imports fell 2.92% year on year, does not mean that the enterprise production appeared significant change. Instead of April crude steel output of 1.85 million tons, up 27% from a year earlier. Although steel prices fell in May lead to enterprise in a small scale production, but the overall steel production is still expected to remain high. Analysts believe that precision cold drawn steel imports decline is mainly due to the represented by the three major mining shipping precision cold drawn steel suppliers' production has peaked, to ensure that Japan and South Korea, Europe and other regions mills for ore orders growth starts back up in agreement, so cut back on to the domestic supply of precision cold drawn steel tube.
