→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.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 corrosion resistance of alloy pipes is specified higher.Shegord Avila,Thin wall steel pipe, thick wall steel pipe.I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:Progreso,So why is the alloy pipe easy to rust after being pickled and passivated by the software?Function of I-beam: where is I-beam mainly used?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:

When selecting I-beam in structural design,Shegord AvilaA335p11 American standard high pressure alloy pipe, 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.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,Shegord AvilaWhich reinforcement manufacturer is 4egmh, 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, such as stainless steel seamless pipe, penetrant testing method is adopted.c. quality inspection is carried out for alloy pipes, so that the whole process of steel pipe processing is under reasonable inspection and supervision, and the product quality is reasonably guaranteed.Quality risk,Performance parameters and application scope of I-beamThe side length of I-beam is small and the height is large, so it can only bear the force in one direction.The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, the thick steel plate has uniform deformation,Shegord AvilaHastelloy G-30 seamless pipe, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size, 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.query,I-beam, 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.Generally there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.Shegord Avila, 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.Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlement Small longitudinal crack
