Yanshan County Bo Yan Pipe Co., Ltd. is located in Yanshan County Industrial Development Zone. North of Beijing and Tianjin and Beijing-Shanghai railway to the east Bohai Sea, Tianjin Port, State Road across the county superior geographic conditions hot elbow, 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" concept of operations, customer service and sincerely willing to domestic hot elbow specifications, customers are welcome to work together to create a better future carbon steel elbow fundamental processes: first welding a polygonal cross-section polygonal ring shell or polygonal ends blockade fan shell, washed over the internal pressure medium within the pressure applied, including action under the pressure progressively become a cross-section polygon round, eventually becoming 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 pressing elbow standards, so simple cutting, precision easy assurance, assembly and welding lunch. (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. Yanshan County Bo Yan Pipe Co., Ltd. Main products: stainless steel, alloy steel, carbon steel high school low pressure bend, bend, three, four, flanges, reducers, tube cap, closed class. Alloy thick-walled elbow fundamental process: first welding a polygonal cross-section polygonal ring shell or polygonal ends blockade fan shells, washed over the internal pressure medium, the pressure applied within the inner cross section under Pressure polygon gradually becomes round and eventually become a circular ring shell. Based on demand hot elbow GB, a circular ring shell can cut four or six 90-degree elbow 60 degree elbow bend or other specifications, the process for the manufacture of elbow and elbow in diameter than the inner diameter Any Size Large bend greater than 1.5, is the ideal way to present the manufacture of large alloy thick-walled elbow.
