China Shipbuilding Heavy Industry news, Chongqing Jiang increasing Shipbuilding Heavy Industry Co., Ltd. is currently the largest independent design and production of model condensing steam turbine QJN002 recently successfully delivered to the user. The largest model of the current condensing steam turbine QJN002 delivered by Jiang Zeng Heavy Industry has a total length of 6.5 meters. The weight of the whole machine is 28 tons and the power is 1700KW . It contains seven stages of impellers and the structure is very complicated. In the development process, all departments of the company cooperated with each other and cooperated with each other to overcome the problems of design and parts processing quality, repeatedly optimize the design and improve the processing of parts. The successful development of QJN002 steam turbine marks the company's design and development of large impeller mechanical products. The manufacturing capacity has achieved substantial results and has demonstrated the design and manufacturing capabilities of developing and manufacturing large impeller mechanical products.
Weld Nuts combine a welding flange with a female threaded nut. This provides a threaded mounting point that can be welded into place.
Offset tab-base weld nuts fit into tight spaces where the through-hole is difficult to reach. The offset allows the nut to align with the mounting hole while providing a wide welding surface.
Tab-base weld nuts weld onto flat surfaces to provide a female-threaded mounting point. Their tab-shaped base is ideal for manual and automated spot welding while their integrated projections channel heat and current to help start the weld.
Round-base weld nuts weld to flat metal surfaces to provide a female-threaded mounting point. Their round base is designed to maximize the weld strength for their size.
Round-base weld nuts weld to flat metal surfaces to provide a female-threaded mounting point. Their round base is designed to maximize the weld strength. The integrated projections channel heat and current to help start the weld.
Hex weld nuts are shaped like normal Hex Nuts, but feature projections for welding them to mounting surfaces and to protect their threads from the weld.
Square weld nuts fit into channels or slots and provide a female threaded mounting point. Their square shape provides more welding surface area and better welds to the mounting surface.
