shortage of different types of large diameter

1, steel production in short supplyAlthough year-on-year in 2012, in 2012, our country's steel production increased, but the market demand for seamless steel pipe steel is too large, resulting in seamless steel tube in short supply, and seamless steel tube is the main material of large diameter seamless steel tube, steel shortage result in a shortage of large-diameter seamless steel pipe, we know that the market demand for large diameter seamless steel tube on the rise, such cases, the making of large diameter seamless steel pipe prices were rising trend.2, shortage of different types of large diameter seamless steel tubeLarge-diameter seamless steel tube with different models, 325, 356, 406, 457, 406, 530, 560, 610, 660.680, 720, 760, 770, 813, 820, 813, etc., on the material is different also, regular material: 20 stainless steel welded pipe, 35 #, 45 #, 16 mn, cr, 20 and 40 cr, Gcr15, etc. Different types, different materials of # large diameter seamless steel tube its USES will be different. On the market for different types of large diameter seamless steel tube requires more, so, hard to avoid can appear a certain type of large diameter seamless steel tube, in a specific period of time, the phenomenon of shortage, so as to make the price increase.3, large diameter seamless steel tube quality improvementFrom one perspective, if the market supply of large diameter seamless steel tube can meet the actual market demand, the price will not have too big increase, with large diameter seamless steel tube industry is mature, for large diameter seamless pipe audit becomes strict, large-diameter seamless steel tube quality requirements, many enterprises in order to guarantee the product quality, to improve production technology, improve production technology, so aeriform in increasing the cost of production of the product, therefore, added value has increased, causing prices to rise. Huge fluctuations in large diameter seamless pipe price not conducive to the stability of the large diameter seamless steel tube industry development, for the enterprise, also is bad, although a short time, enterprises' income, but in the long run, unstable prices, is not conducive to enterprise development, price stability, maintenance industry needs large diameter seamless steel tube enterprises together, at the same time also need reasonable policies and measures.
