North of Beijing and Tianjin and Beijing-Shanghai railway to the east Bohai Sea, Tianjin Port, State Road across the county superior geographical conditions, abundant local resources, for my company's development has laid a good foundation. Best-selling products, and exported to South Korea, Vietnam, Singapore, Malaysia and other countries. I used to pursue "science and technology first, gaining the upper hand, quality, customer supreme, credit first" business ideas, is willing to domestic and foreign users and sincere welcome customers to work together to create a better future carbon steel elbow fundamental process is: First solder a polygonal cross-section polygonal ring shell or polygonal ends blockade fan shell, the internal pressure washed over medium hot elbow, less pressure is applied, including action under pressure from the polygonal cross-section gradually become round and eventually become a circular ring shell. According to demand, a circular ring shell can be cut into 4 or 6 90 ○ 60 ○ elbow bends or other specifications of the elbow, the process for the manufacture of elbow and elbow in diameter than the inner diameter of any size greater than 1.5 large elbow, is the ideal way to present the manufacture of large carbon steel elbow. The carbon steel elbow main advantages of manufacturing process table now following aspects: (1) without the tube as the starting material, equipment and pipe can save tooling costs and wanton large-diameter and wall thickness can be obtained relatively thin carbon steel elbow. (2) the blank is flat or developable surface, thus cutting simple, easy to ensure accuracy, easy assembly and welding. (3) Due to the above two reasons, it is possible to shorten the manufacturing cycle, greatly reducing the cost of consumption. Because it does not demand any special equipment, particularly suitable for on-site processing of large carbon steel elbow. Carbon pressing elbow, pressing elbow, Bo Yan Pipe supplied by Bo Yan Pipe Co., Ltd. Yanshan County. Yanshan County Bo Yan Pipe Co., Ltd.
