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, 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 also known as H-beam thin web and light weight. Wide flange I-beam, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Introduction to product knowledge of alloy pipe:Vega,Identification method of galvanized pipeMixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.Portosi,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.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.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.

Difference and application description between H-beam and I-beamAccording to the section shape, the steel pipe is divided into:Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.production,Introduction to product knowledge of alloy pipe:Mixed Scabs are distributed periodically, can be accurately positioned,VegaHow much is a ton of welded pipe,VegaWhere do you sell welded pipes, and is resistant to impact and vibration Moreover, it has good versatility and combination, and has a variety of C-section steel and size selection to ensure its flexibilitymanufacturer,Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %The production methods of seamless pipe are roughly divided into cross rolling method and extrusion method. The cross rolling method is to drill the tube with a cross roll, and then extend it to the rolling mill. This method has fast production speed, but has high requirements for the workability of the blank. It is mainly suitable for the production of carbon steel and low alloy steel pipes. The extrusion law is to pierce the blank or ingot with a punch, and then squeeze it with a steel pipe with an extruder. The efficiency of this method is lower than that of cross rolling method. It is suitable for producing high-strength alloy steel pipe. The billet or ingot must be heated before cross rolling method and extrusion method. The produced steel pipe is called thermal correlation. Steel pipes produced by hot working can sometimes be cold worked as needed. There are two methods of cold working. One is cold drawing. In other words, pull the pipe to the pipe and tilt it to make the steel pipe gradually thinner and longer. Another method is cold rolling. The method of applying the hot smoke invented by brother to cold processing. The cold working of seamless pipe can improve the dimensional accuracy and finishing of steel pipe,VegaAll selection of Cold Drawn Welded Pipe, and improve the mechanical properties of materials.Due to the unique performance of I-beam,Plan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min.What are the uses of I-beam?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.
