Stainless steel seamless pipe for oil and gas drilling

The C02 corrosion of oil, gas wells in the safety of consumer scores. However, due to the high price of dual phase steel, the use of restricted. The beginning of the United States and Europe developed alternative dual phase steel data to stop research. The first is to start in Europe to stop using the super martensitic steel S13Cr instead of dual phase steel. But a small amount of stop extensive and in-depth application research and constitute a genuine industrialized mass consumption to occupy the market is not Europe and the United States developed countries, but excel in Japan. Japan's seamless stainless steel pipe consumption factory in twentieth Century from the early 80 years beginning, all have their own characteristics of the series opened. In the early stage of industrial consumption, the production was limited by the extrusion machine consumption. Sumitomo Metal and Kawasaki Steel and skills related to achievement in the last century 80 ~ 90 years concentrated effort on the rolling pipe mill (small diameter) and active rolling pipe mill (large and medium caliber) pipe consumption C13Cr stop the research and reform of secondary equipment stopped responding. In recent years, the Japanese C13Cr based chromium stainless steel seamless pipe production increased significantly, accounting for half of the world's stainless steel pipe market. After 20 years of sustained development tasks, and finally achieved a reward.
