Established in March 2005, Hebei Changfeng Steel Tube Manufacturing Co., Ltd, briefly as CFST was located in North China, Cangzhou Economic Development Zone, Changzhou City, Hebei Province, China, which is about 240 Kilometers distance to Beijing and 140 Kilometers to Tianjin port.
CFST, invested as a specialized manufacturer of high frequency electrical welded steel pipes/tubes, was developed on the basis of Hebei Changfeng Machinery Manufacturing Co., Ltd and Hebei Changzhou Steel Structural Engineering Co., Ltd. Till 2011, CFST has been the biggest and leading manufacturer of high frequency ERW steel tubes from 8" to 26"(219mm-660mm) and is one of the 3 Chinese manufacturers that can produce HFW/ERW steel tubes from 20" to 26"(508mm-660mm).
CFST is now covering an area of about 130000 m2 and has 628 employees. The main production equipment includes a set of 406mm HF welded steel tube making unit and a set of 630mm HF welded steel tube making unit. The annual output of ERW/HFW steel tubes has reached 360000 Metric Tons and annual sales revenue has exceed USD300 millions. Till 2011, CFST has finished its periodical development on production capacity, quality level orientation, and technical innovation.
The main facilities like high frequency welding machine was manufactured EFD in Norway, its online ultrasonic non-destructive detection system was imported from Israel which was manufactured by SCANMASTER and the hydrostatic test system was imported from German, maximum test pressure reaches 70 Mpa. It's heat treatment part use 2000KW IF annealing furnace, to ensure the strength and toughness of the weld metal and heat affected zone matching with the pipe body.
CFST, as a leader in ERW steel tube industry, has been certified by ISO9001-2008, API 5L and API 5CT and our brand "Changfeng" is listed as national famous brand.
