The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, expressed as No. ~ No., and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources but also reduce consumption, not occupy the natural environment but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.Newvitas, Platform reinforcement mesh is a widely used reinforcement mesh product, such as industrial maintenance platform, berm, municipal administration, electric power, coal mine and other fields, and has the strongest resistance to surface impact, especially the reinforcement mesh with a cross bar spacing of mm has a strong ability to resist lateral impact. Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis.Muhoroni, Small longitudinal crackHowever, what we need to do now is to improve the production technology level of China&#;s production process of C-section steel,NewvitasHow much is I-beam No. 16 per ton, and step up the formulation of relevant industry standards and inspection standards. C-section steel manufacturers should keep close contact with truck manufacturers and communicate more. In this way, it is more conducive for C-section steel manufacturers to produce C-section steel products suitable for truck industry.I-beam

→ the two surfaces of the flange are parallel to each other, process and install.What is the of defect detection of seamless pipe? Magnetic particle testing or penetrant testing of seamless pipes can effectively find surface defects such as cracks, folds, double skin, hair lines, pinholes and so on. Because of its high detection sensitivity, magnetic particle detection method should be preferred for ferromagnetic materials. For non ferromagnetic materials, penetrant testing method is adopted. Miscellaneous scabMeticulous workmanship,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.I-beam, also known as steel 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.Stages needing attention in the production and manufacture of alloy tubes

H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange,NewvitasHow much is the price of I-beam per meter, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.Process inspection,Xhy- series high hardness alloy I-beam; Undertake drawings and process wear-resistant pipes（ Φ ≥mm）； Undertake the processing and production of vulnerable parts of cement machinery; Welding technology consultation and service; The wear-resistant layer of alloy wear-resistant plate of high chromium heap welding flux cored wire series is mainly high chromium, as well as manganese, molybdenum, niobium, francium and other components. The alloy carbide formed has strong stability at high temperature. Welded steel mesh is aesthetically pleasing.Passivation treatment operation of alloy pipeNewvitas,Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation. Mixed pass system. According to the characteristics of rolling mills and products, in order to give full play to the advantages of their respective systems and overcome their disadvantages, mixed pass system is often adopted, that is, the combination of more than two systems. For example, straight leg cross rolling pass system is adopted for finished hole and front hole of finished product, and bent leg cross rolling system is adopted for other passes; or direct rolling system is adopted for rough rolling hole and straight rolling system is adopted for the last ~ finish rolling holes Leg oblique tie hole, etc.Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materials
