Generally, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, there is no harm to carry out hot galvanizing in the middle and later stage.The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, 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.Gabrovo, the wall thickness of high-quality and smooth steel is particularly thick. Because the thicker the wall thickness of the product, the higher the economy and practicability. The thinner the wall thickness, the greater the processing cost and opportunity, and the higher the resource cost. Secondly, the process of smooth steel also determines its limitations. Generally, smooth steel has low precision, uneven wall thickness, low brightness inside and outside the pipe, high length cost, pockmarks in the internal appearance, and black spots are not easy to remove. Again, the inspection and shaping need to be processed offline. Therefore, it has its advantages in high pressure, high strength and mechanical structure materials. In the process of use, seamless pipe has also entered the market in recent years. With the growth of market demand, the advantages of seamless pipe have also been stimulated. But there are also many fakes and fake products on the market. Be careful when you choose.→ under the same section load,GabrovoHow much is 14 I-beam, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Szentendre,GabrovoReinforcement material list,GB No. I-beam is in height, in leg width and in waist thickness. Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, when the extrusion molding is used for mm diameter pipe fittings, the investment of machinery and equipment is less, so the raw material consumption is also very small, and the technology is relatively perfect. Once the tube size is increased, the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore, the automatic control system will be upgraded. H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter 'H'. The flange of hot rolled H-beam is wider than that of I-beam, with large lateral stiffness and strong bending resistance. Under the same specification, H-beam is lighter than I-beam.

Application characteristics of I-beam: The zinc layer obtained by electroplating is relatively pure which corrodes slowly in acid, alkali and other fog, and can effectively maintain the steel matrix;So why is the alloy pipe easy to rust after being pickled and passivated by the software?Application process,What is the purpose of flat steel Frame line crackWhat are the uses of I-beam?

c. quality inspection is carried out for alloy pipes, so that the whole process of steel pipe processing is under reasonable inspection and supervision,GabrovoHow much is hot dip galvanized pipe per meter, and the product quality is reasonably guaranteed.Sales Department,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, chromizing boronizing, siliconizing and so on are commonly used in production.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, such as stainless steel seamless pipe, penetrant testing method is adopted.After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.Gabrovo,H-shaped steel groove is deep and thick and can withstand forces in two directions.Requirements of alloy tubes for low and medium pressure boilersWhether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.
