Seamless implementation of international: GB8162-2008 (structural pipe), GB8163-2008 (fluid pipe), GB3087-2008 (low and medium pressure boiler tubes), GB5310-2008 (high-pressure boiler pipe), GB6479-2000 (fertilizer tube) Demand GB9948-2006 (petroleum cracking tube), etc., made of 20 #, 35 #, 45 #, 16Mn, 27SiMn, 15CrMo, 12Cr1MoV, 35CrMo, Cr5Mo, 10CrMo910, T91 and other high alloy pipe and thermal power development are inseparable. 1995 domestic installed capacity of 200 million kW. According to government plans in 2000 to reach 290 million kW, ie additional 16 million kW annually. Where the fire (by 75% calculation) 15crmo, an annual increase of 12 million kW 15crmo manufacturers, boiler manufacturers kW consumption per square meter 100t high-pressure boiler pipe imports 15crmo, the annual consumption of 120 000 t. Due to the introduction of the overall import boilers, actually consumed less than this number. Plus the power plant construction (1.7t / Wan kW), thermal power holdings maintenance (6.5t / Wan kW) and with high alloy steel pipe similar performance requirements needed, and in recent years, annual consumption is estimated at about 300 000 t. With the increase of ownership in the future will be the amount of maintenance required tube top. 15crmo manufacturers _ Katherine source steel (certified) _ Siping 15crmo provided by source Pipe Co., Ltd.
