Product Description: Q390B coiled plate and medium plate are two different steel products, with certain differences in their smelting processes and performance.First, in terms of smelting process, the smelting processes for Q390B coiled plate and medium plate are basically the same, both adopting the oxygen top-blown converter smelting, continuous casting, and continuous rolling process. However, in the specific smelting process, the medium plate's smelting process is more refined, requiring higher purity of molten steel and stricter control of chemical composition. Therefore, the smelting of medium plate is more challenging, and the production cost is relatively higher.Second, in terms of product performance, both Q390B coiled plate and medium plate have good comprehensive mechanical properties and machinability, making them suitable for various machining and manufacturing fields. However, due to differences in smelting processes and production costs, there are certain performance differences between Q390B coiled plate and medium plate.Specifically, Q390B coiled plate has higher strength and hardness, making it suitable for manufacturing mechanical parts and structural components that need to bear larger loads. At the same time, due to the smaller thickness of Q390B coiled plate, its yield strength is relatively lower, giving it good impact toughness, making it suitable for manufacturing parts and structural components that need to withstand impact loads.On the other hand, medium plate has higher tensile strength and yield strength, making it suitable for manufacturing mechanical parts and structural components that need to bear higher loads. Additionally, medium plate has good weldability and machinability, making it suitable for manufacturing parts and structural components that require welding or complex processing.Furthermore, there are certain differences in the applications of Q390B coiled plate and medium plate. Q390B coiled plate is mainly used in construction, bridges, ships, vehicles, and other fields, while medium plate is primarily used in manufacturing various mechanical parts, boilers, pressure vessels, and other large mechanical products.In summary, the smelting processes for Q390B coiled plate and medium plate are basically the same, but the medium plate's smelting process is more refined, and its production cost is relatively higher. In terms of performance, Q390B coiled plate has higher impact toughness and good machinability, making it suitable for mechanical parts and structural components that bear larger loads; while medium plate has higher strength and weldability, making it suitable for mechanical parts and structural components that bear higher loads. Additionally, there are certain differences in the applications of Q390B coiled plate and medium plate. When selecting, it is necessary to choose based on specific usage requirements and design needs. more>

Product Description: Pei Yingying  1862587  9268The characteristics of aluminum alloy anodes are: high theoretical power generation, low specific gravity, which allows for the design of long-life anodes with light weight, convenient manufacturing, simple production processes, ample material sources, and excellent electrochemical performance. They have the function of initially regulating current and potential and are widely used for the protection of internal marine oil equipment, external submarine pipelines, platform jackets, etc. However, aluminum anodes have the disadvantages of lower current efficiency compared to zinc anodes, poorer dissolution performance than zinc anodes, and unsuitability for high-resistivity media.Currently, the development of aluminum alloy anodes is moving towards improving current efficiency, enhancing dissolution performance, and adapting to high-resistivity media as well as high and low-temperature seawater environments. For example, to effectively protect offshore oil pipelines, bracelet-type sacrificial anodes are widely used in the eastern South China Sea, making aluminum sacrificial anodes more suitable for installation. The generated current meets the pipeline requirements as much as possible to achieve the desired protection lifespan.(3) Sacrificial Anode Protection DesignThe effectiveness of sacrificial anode protection mainly depends on the sacrificial anode material and a reasonable sacrificial anode protection design. The basic steps are as follows:1) Collect design parameters.Gather information on material, surface condition, geometric shape, and relevant environmental conditions. Set the protection current density, understand the protection area and structural characteristics, and calculate the total protection current required based on the protection lifespan.2) Select sacrificial anode material and specifications.Based on the protection lifespan and requirements, choose the sacrificial anode material (such as zinc anodes or aluminum anodes). According to installation and structural conditions and the protection current, determine the protection distance of the anode to derive the anode's size and specifications.3) Calculate the number of anodes and verify.Pei Yingying   1862587   9268 more>

Product Description: 09MnNiDR steel plate is a type of steel plate used for low-temperature pressure vessels, offering excellent low-temperature toughness and strength, suitable for low-temperature environments down to -70°C. Its chemical composition mainly includes carbon (C), silicon (Si), manganese (Mn), nickel (Ni), vanadium (V), niobium (Nb), aluminum (Al), phosphorus (P), and sulfur (S), with carbon content not exceeding 0.12%, manganese content between 1.20% and 1.60%, and nickel content between 0.3% and 0.8%. This steel plate can be delivered in normalized or normalized + tempered quenched + tempered conditions to ensure its good performance at low temperatures.The production locations of 09MnNiDR steel plate include Wuyang Steel, Xiangtan Steel, Xin Steel, Wuhan Steel, Chongqing Steel, Nanjing Steel, Jinan Steel, among others. Its physical quality is very high both domestically and internationally, even surpassing that of some foreign steel plates of the same grade. This steel plate has been included in China's GB150-1998 "Steel Pressure Vessels" standard, while the maximum thickness of 0.5Ni low-temperature steel plate in EN10028-4 is 50mm, and the U.S. -70°C grade low-temperature steel plate is 2.3Ni steel, but their low-temperature impact energy indicators are far lower than those of China's 09MnNiDR steel plate.The microstructure of 09MnNiDR steel plate is ferrite + a small amount of pearlite. Due to its low carbon equivalent (≤0.44), it has a low hardening tendency, is not prone to forming cold cracks, and the weld has good plasticity and toughness. During welding, preheating is usually not required, but if the plate thickness is large or the joint rigidity is high, preheating should be considered. However, the preheating temperature should not be too high to avoid affecting the grain size of the heat-affected zone.09MnNiDR steel plate has a wide range of applications, mainly used in the manufacture of low-temperature storage tanks, pressure vessels, heat exchangers, towers, reactors, and other equipment, especially in low-temperature storage and transportation equipment in industries such as petroleum, chemical, and natural gas. Additionally, it can be used to manufacture key equipment such as nuclear reactor pressure vessels, boiler drums, steam turbines, and coolers.09MnNiDR16mm            25001170009MnNiDR16mm            25001150009MnNiDR16mm            25001160009MnNiDR16mm            25001170009MnNiDR16mm            25001220009MnNiDR16mm            25001160009MnNiDR16mm            25001170009MnNiDR16mm            250011500 more>
