Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.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, there are many things that must be paid special attention to. Let&#;s take you to know:Sun Pange,Seamless pipe has a high position in steel pipe, and there are many large factors. The main usage has accounted for more than %, which is applicable to all walks of life. Seamless pipe factories in China are widely produced. At present, the number of factories in China is also increasing every year, which is determined by the nature and production conditions of seamless pipe. The common production processes and processes are more complex.Classification introductionResita,Metallization: refers to the process of penetrating metal atoms into the surface layer of alloy steel pipe. It is to alloy the surface layer of steel so that the workpiece surface has the characteristics of some alloy steel. Aluminizing,Sun PangeHow much is I-beam wholesale, chromizing, boronizing, siliconizing and so on are commonly used in production.Because all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, simple construction,Sun PangeHow much is a ton of straight welded pipe, 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, can be accurately positioned, it has good versatility and combination, and has a variety of C-section steel and size selection to ensure its flexibility

Some applications of I-beam:The electric welding reinforcement mesh can reduce the damage and consumption to the reinforcement processing process. According to statistics, after deducting the steel consumption increased by unit lapping, it can also save about % of the steel. After it is transported to the site according to the construction degree of the project, it can be hoisted to the working face. There is no need to set a reinforcement processing site on the site, it can also solve the problems of noise pollution caused by straightening reinforcement.After the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ %, the solution temperature is ~ ℃, and the solution time is min. Then dry.Where is it,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, the axial movement is small the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body. Judged as failing.

Because the section size of ordinary I-beam and light I-beam is relatively large and narrow,Sun PangeDirect sales of welded pipe manufacturers, the moment of inertia of the two main shafts on the section is quite different, which limits its application range. I-beam shall be selected according to the requirements of design drawings. In the structural design, the use of I-beam should be reasonably selected according to the mechanical properties, chemical properties, weldability and structural size of I-beam.Good quality→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Speed up the construction progress: weld the mesh with reinforcement to allow the rapid construction of the project. The required laying of welded steel bars is provided, so concrete can be poured, steel cutting, stitching, etc., and the arrangement can be strengthened. ？ saving construction time? The construction progress is greatly accelerated and the construction period is shortened.Classification introductionSun Pange,Passivation treatment operation of alloy pipeAlloy tube is widely used in our daily life, which provides us with great assistance. So what industries are alloy tubes applied to? Let&#;s follow the steps of all manufacturers and have a look together:Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %
