MeliciaHow much is a 12 cm I-beamThe outer diameter standard

d. All machines and equipment in a production line can connect with the software of the computer data collection system to complete the timely transmission of data information, and the performance parameters in the production process are monitored by the central control room.I-beam, also known as universal beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Melicia, Carbon: the higher the carbon content, the higher the hardness of steel, but the worse its plasticity and toughnessAll 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.Villa-Bisono,The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages. Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, etc.→ under the same section load the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.

Alloy pipes can be used for heating (cooling) projects.The use of welded steel mesh can make the project construction convenient. As long as the welded reinforcement mesh is laid as required,MeliciaHow much is 150 welded pipe per meter, eliminating the links such as on-site cutting, placing and binding of reinforcement one by one.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, thin web and light weight. Wide flange I-beam, also known as H-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.Welcome to inquireWith the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, which is easy to lose stability for load-bearing columns.Passivation treatment operation of alloy pipeAdvantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumption

Because all parts of I-beam are arranged at right angles,MeliciaHow much is 32 galvanized pipe, 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.Sincere service,Requirements of alloy tubes for low and medium pressure boilersGalvanized pipe refers to the shape and high frequency of hollow square steel pipe welded by the back of the steel pipe during the hot rolling or cold rolling of galvanized steel plate or cold bending of galvanized steel plate, or before the galvanization of cold hollow pipe. Galvanized. Galvanized square pipe can be divided into hot galvanized pipe and cold galvanized pipe from the production process. This is because the two galvanized pipes are different, which also leads to many different physical and chemical properties. Judged as failing.Melicia,MeliciaQuotation of high pressure alloy pipe,GB No. I-beam is in height, in leg width and in waist thickness. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.The high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment, the surface layer of parts must be removed to remove waste. At a higher temperature, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.
