H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel, profiled steel plate, etc.). Due to the reasonable section shape they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type, the flange of H-section steel is widened, and the inner and outer surfaces are usually parallel, so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable, series and models are complete, which is convenient for settingI-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.Dahaon The zinc layer obtained by electroplating is relatively pure, which corrodes slowly in acid, alkali and other fog, and can effectively maintain the steel matrix;All the cracks occur at -mm away from the edge below the alloy pipe, showing a 'high mountain' shape.Temaceae,After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, a layer of zinc is deposited in the pipe.H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel,Dahaon12Cr1MoVG thick wall alloy pipe, profiled steel plate, etc.). Due to the reasonable section shape, they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type, the flange of H-section steel is widened, and the inner and outer surfaces are usually parallel, so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable, series and models are complete, which is convenient for settingPassivation treatment operation of alloy pipe

H-shaped steel groove is deep and thick, and can withstand forces in two directions. Divided by weld -- straight welded pipe and spiral welded pipe. Peak crackProfessional is king,I-beam, also known as universal beam,DahaonHow much is hot dip galvanized pipe per meter, 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.→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.Key technical characteristics of alloy pipe:

The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.Process inspection,I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.What are the quality protection measures for galvanized pipe during welding Judged as failing.Dahaon,Main uses: as a finished material,Dahaon25 how much is a meter of galvanized pipe, tools and mechanical parts, and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles tractors, railway transportation and other machinery.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, the part of the workpiece can maintain the toughness and plasticity of low-carbon steel.Key technical characteristics of alloy pipe
