The alloy tube can be hardened by induction heating, so it has excellent rolling fatigue characteristics and corrosion resistance. Therefore, this kind of steel has been widely used as the material of rolling mill flap ball screw in rolling mill manufacturers. In addition to the excellent properties of cronidur steel, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment, and its application range is expected to be further expanded.I-beamSan jodataha,Classification by useAdvantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumptionShakiso,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.Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.

Difference and application description between H-beam and I-beam The zinc coating is thick, the crystallization is detailed, uniform and non porous, and the corrosion resistance is excellent;Because alloy pipe is a very unique pipe fitting, we must use appropriate methods to carry out installation in the case of installation, so as to ensure the performance index of the data. Generally, when installing alloy pipes, so as to ensure that the raw materials can be fixed very well. Therefore, when we carry out use, we must ensure the quality of flanges and elbows,San jodataha10CrMoAl alloy pipe,San jodatahaInconel 601 alloy pipe, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.Excellent service,Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);Alloy tube is widely used in our daily life, which provides us with great assistance.The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.

Greatly reduce the environmental pollution caused by abrasion, damage and blanking and increase the labor cost of material cleaningJob description,Requirements of alloy tubes for low and medium pressure boilersAccording to the section shape, the steel pipe is divided into:I-beam also known as universal beam,What is the purpose of flat steelAlloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, a large amount of liquid can be transported with an annular tube. In addition, the bearing force is more symmetrical. Therefore, most seamless steel pipes are round steel pipes. 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,San jodatahaHow much is 25 hot-dip galvanized pipe per meter, 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 used
