(10 billion Steel Pipe Manufacturing Co., Ltd., for petroleum and petrochemical tube) Hebei, year-round to provide customers with OCTG pipe for petroleum and petrochemical pipes and oil pipes, oil pipe for oil and gas well drilling and oil and gas delivery. It includes oil drill pipe, casing, and pumping 

 Tube. Oil drilling pipes are mainly used to connect the drill collar and bit and pass the drilling power. Oil casing is mainly used for drilling and completion of the sidewall of the support in order to ensure the normal operation of the wells in the conduct and completion of the drilling process. Pumping tubing mainly oil wells at the bottom of the oil, gas input 

 Sent to the ground. According to steel the strength of casing can be divided into different grade of steel, that is, of J55, K55, N80, L80, C90, the T95, P110, Q125, V150. And so on. Well conditions, different depth of the steel grade is also different. Also requires the casing in corrosive environments with corrosion resistance. In 

 The complex geological conditions also require the casing with anti-collapse performance. Sales Hotline 0317-5128533 Mobile: 13323270092 Fax :0317-6322267 Contact: Wang Yuehong URL: http://www.baiyipipe.com
