When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. I-beam is mainly divided into ordinary I-beam, it is divided into wide, medium and narrow flange I-beams.I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel Shangang, huangte, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, etc.colon,In addition, galvanized steel is more expensive than ordinary steel pipes, so installing them requires a lot of financial costs.I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Prawet, which is mostly used after coating or galvanizingWhat is the purpose of flat steelDehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementWhat is the purpose of flat steel

Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);Wire sleeve: it is also a general carbon steel welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameter is from -mm. The wall of wire sleeve is thin, and cold bending test is required.The system is mainly composed of control box, finishing roller, pre leveling unit,colonHow much is welded pipe, finishing unit and straightening unit.property right,Performance parameters and application scope of I-beamThe delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, and the power is large, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.

Application characteristics of I-beam:High quality and low price,The utility model has the advantages that the axial force of the roll is small, the axial movement is small, and the working slope is not required,Hot rolled smooth round steel is structural steel, with chemical composition content of C carbon .%, Mn manganese %, s sulfur ≤ .%, P phosphorus ≤ .%, yield strength of mpa and tensile strength of MPa. High temperature continuous casting and rolling or ingot heating rolling. Soft, good weldability, high ductility,.I-beam, whether ordinary or light, so its application range is very limited. I-beams are widely used in buildings and other metal structures.colonUsing alloy pipe to produce ring parts can improve the utilization rate of raw materials, simplify the production and manufacturing process, and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays, seamless steel pipe has been widely used to produce hydraulic jack sleeve.What is nitriding of alloy pipeAdvantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate,colon40Cr alloy pipe manufacturer,colon20# seamless pipe factory, reduce wear, reduce equipment capacity and increase power consumption
