6.The Design of Hydraulic Transmission System in the Mechanism of 650 Longitudinal Shearing Set
8.A saw consisting of a tough, fine-toothed blade stretched taut in a frame, used for cutting metal.
9.Owned steel wire welding equipment, Telegraph kits More equipment, frame welding equipment, network coverage Zhangjin equipment, corrosion spraying equipment through-train production processes, 2003 with an annual package More fencing, galvanized fence were 200,000 square metres, of which frame-assembly fencing 40,000 square metres (over 3,500 sets), on-site construction around 25,000 square metres.
10.The risk of using the thermally insulated pipeline is that the exterior layers covering the steel pipe may be pulled off if the shear stress on the interface induced by the pullout force from the tensioner is greater than the binding force between two neighboring layers during installation.
