C - section steel is reliable and stable in stress, can be accurately positioned, 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 flexibilityNitriding: also known as nitriding, it is the process of penetrating nitrogen atoms into the surface layer of steel. At present, gas nitriding is widely used in the production of alloy steel pipe.Kangjiqi, Because the zinc coating has excellent ductility,KangjiqiPrice of 12Cr1MoVG alloy pipe, it can be formed by cold stamping, rolling, bending and so on without damaging the coating.Because all parts of I-beam are arranged at right angles, 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.Paine,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, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, 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.When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project,KangjiqiWholesale price of high frequency welded pipe, there are many things that must be paid special attention to. Let&#;s take you to know:Passivation treatment operation of alloy pipe

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. In order to ensure the welding quality of pipes, welders shall be trained, tested and qualified. In addition to the basic theory, the welder should consider the operation skills. The pipe welding process may include several postures of overhead welding, vertical welding and overhead welding (when the pipe cannot rotate). The size of current should be selected to take into account the formation of vertical welding and overhead welding (some pipes are not very large, the stability and formation of arc should be controlled, It can swing properly, and the forming shall be well combined with the necessary swing.The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid, sodium cyanide, etc., which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore,The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -. 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.Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, 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, unique and convenient installation, 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.

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, which can be used ready-made for components ladders, bridges and fences. Flat steel can also be used as blank for welding rigid steel and slab for laminated thin plate.Which one is better,I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRC After chromate passivation, the zinc coating forms white, colorful and military green which is beautiful and generous and has certain decoration;Passivation treatment operation of alloy pipeKangjiqi, Small longitudinal crackMain uses: as a finished material, flat steel can be used to make hoop iron, 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.I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates cast wear-resistant plates, cast stones,Kangjiqi15CrMo alloy pipe in stock, rubber, polyurethane, it has irreplaceable comprehensive excellent properties.
