~ 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.As shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, which makes the outer flange thin and the inner flange thick. Therefore, the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance.Antigo kuscatland, Application of galvanized pipeRequirements of alloy tubes for low and medium pressure boilersKaisariani,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.When it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering, mining and other industries to meet the provisions of cold cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.Defects of alloy pipe and solutions:

H-section steelIn our daily life and work, we can often see a lot of steel products. At the same time, among many steel products, the figure of galvanized pipe is particularly prominent. This is because this kind of pipe will be applied to many engineering construction we often see in our life. There are also countless products processed with this kind of pipe. For example, in the field of mechanical equipment processing we often see, the application of galvanized pipe is more frequent. Let&#;s discuss the application scope of this kind of pipe today.Dry processing technology: after passivation treatment, parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.safety requirements ,Stages needing attention in the production and manufacture of alloy tubesThe finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length wear resistance and maximum temperature of ℃I-beam is widely used in buildings or other metal structures.

I-beam has wide flange, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles,Antigo kuscatland1Cr5Mo alloy pipe, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.discount,Antigo kuscatland10Cr9Mo1VNb alloy pipe,Application characteristics of I-beam:Galvanized pipe is a layer of galvanized ordinary steel. This is a layer and is a great anti-corrosion protection.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.Antigo kuscatland,I-beam is widely used in buildings or other metal structures.→ compared with general section steel,Antigo kuscatland2205 duplex steel welded pipe, 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.Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materials
