The shape of I-beam is similar to that of H-beam. What is the difference between them?It is a potential rolled strip steel with rectangular section for general purpose. It is very common on construction sites. Its specifications are expressed in thickness and width. At present, most of the flat steel on the market are finished steel,The two ends of the steel produced by the seamless pipe manufacturer shall be cut into right angles, and the burrs on the surface shall be removed, which is the raw material used by the seamless pipe manufacturer. The embryo prototube embryo needs to be cut by a cutting machine to form an embryo material with a length of about one meter, which is sent to the furnace for heating through the conveyor belt. The billet is sent to the furnace. After internal heating, the temperature is about degrees, and the fuel used is often ethyne. Temperature control in the furnace is a very key factor.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.TACARIGUA,Classification introductionClassification introduction Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, and the waist has an included angle with the horizontal axis.

Passivation treatment operation of alloy pipeGalvanized pipe has excellent corrosion resistance. Compared with traditional steel, its application life is longer. Secondly, this kind of pipe has strong resistance to baking. In case of critical situation, it will not lead to the collapse of building structure in a short time. In addition this kind of pipe also has a practical advantage, that is, it is more convenient and lighter when carrying out the construction and installation. The operators save time and labor when carrying out the construction, it is not difficult to understand why the galvanized pipe is so favored by various construction units.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,MariborDN50 seamless pipe price, 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 If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.Good quality, Frame line crackI-beam is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.

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.offer, Hot hole breaking cold rolling method. This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill, cold rolling by few station mandrel mill, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way, the advantages of high efficiency, low metal material consumption, excellent product quality and excellent automatic control system are more and more widely used. The competitive advantage of the latter one is low cost and short whole process. It is suitable for the processing and manufacturing of CrMoG alloy pipes with large quantities, small types, multi specifications and high precision. Therefore, it is widely usedThere are several ways to clean galvanized pipesa. In the forming process, the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size,Maribor25 how much is a ton of galvanized pipe, specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe.Maribor, Peak cracka. In the forming process, the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size,MariborAlloy pipe 12Cr1MoVG, specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe.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, 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.
