I-beam is widely used in buildings or other metal structures.The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -, rectangular section and slightly pure edge. Flat steel can be finished steel or it can be used as blank for welded pipe and thin slab for laminated thin plate.Compastra asuya,Transformer tube: it is used to make transformer heat dissipation tube and other heat exchangers. It is made of general carbon steel. Flattening, zigzag and hydraulic tests are required. Steel pipes are delivered in fixed length or double length, and there are certain requirements for the tortuosity of steel pipes.→ wide flange and large lateral stiffness. Strong bending resistance.Leganese,Carburizing: carburizing is the process of penetrating carbon atoms into the surface layer of steel. It also makes the low-carbon steel workpiece have the surface layer of high-carbon steel, and then after quenching and low-temperature tempering,Compastra asuyaHow many kilograms of 16 yuan steel bar per meter, the part of the workpiece can maintain the toughness and plasticity of low-carbon steel.According to the theory of steel structure, the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down. Frame line crack

Alloy tube is widely used in our daily life, which provides us with great assistance. So what industries are alloy tubes applied to? Let&#;s follow the steps of all manufacturers and have a look together:Cold.It can withstand continuous moderate impact and can provide composite plates of various thicknessesWhere to sell API, and the test standards of alloy pipes are also different. Alloy pipe has high hardness and can be used at many levels, most of which is prestressed reinforcement. Where plastic deformation is not specified but compressive strength is specified, such stainless steel plate can be applied.b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.Because all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used. The inner and outer sides of the flange of the I-beam are parallel or close to parallel and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of I-beam is smaller than that of ordinary I-beam with the same height of web, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam.

Requirements of alloy tubes for low and medium pressure boilersHow much does it cost?,The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust. Seamless pipe is resistant to corrosion, acid, alkali, salt and atmospheric environment, high temperature, impact and fatigue, does not need regular maintenance, and the effective life is more than years;All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.Compastra asuya, as well as manganese, molybdenum, niobium, francium and other components. The alloy carbide formed has strong stability at high temperature.Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);Classification introduction
