PetroChina high-level oil industrial welded stainless steel pipes
Mostly utilized at middle and high oil level oil industrial welded stainless steel pipes, new steel vanadium steel, manufactured cars and trucks in recent days. This solution content of dangerous components, sulfur, phosphorus, and much reduced than for traditional scales, and significantly less than optimal size. Sha steel, based on the investigation group accountable for Academia Sinica's analysis staff introduction, steel smelting of low phosphorus, low sulphur steel has reached domestic advanced level and has basically met the ability to mass production, for the future development of higher levels of pipeline steel and laid a solid foundation.
Modern day pipeline belongs to low or additional low carbon microalloyed steels are high technology and high added-value products, able to withstand harsh environments which include the test of high pressure and cold, erosion. Sand is at house and early improvement of pipeline steel companies, whose market place possession rate was amongst, but because the high content of sulphur in molten iron and phosphorus, doesn't have the function of dephosphorization of hot metal pretreatment causes, restricted to development of higher grade pipeline steel. In an effort to transform this scenario, 2006 by steel and new steel vanadium investigation group at the Academia Sinica, carried out on a low phosphorus, low sulphur steels for oil casing analysis and development perform. This project such as BOF, LF refining, RH furnace refining and continuous casting of numerous processes, including testing. So that you can assure its accomplishment, steel study staff in the Institute plus the new steel vanadium on test program performed a variety of thorough discussion, finalizing a concrete pilot project. Their dephosphorization processes and optimizing the usage of previously created measures for example low sulphur steel smelting technology, succeeded in breaking the long-standing shagang improper production of low phosphorus, low sulphur steel technical setbacks. Not too long ago, the research group at Sha steel vanadium steel mill had a package of industrial test, test steel tempered price 100%. Trial eight furnace steel, sulphur and phosphorus contents all within the essential variety. It is actually reported that the domestic production of welded steel pipes companies, steel such a very low content of sulfur and phosphorus can reach continues to be a minority.
