Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementI-beam is widely usedmouse, Main machines and toolsGreatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaningJilib,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:The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.Determined by the shape, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam it can greatly improve the bearing capacity and save metal by % ~ %.

With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, which is easy to lose stability for load-bearing columns. The zinc layer obtained by electroplating is relatively pure which corrodes slowly in acid, alkali and other fog, the interval is min.Customer first,After the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution,mouseQ235B welded pipe manufacturer, ~ 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.Heating surface pipes, economizers, superheaters, reheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)H-section steel

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. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam,mouse40CrMnMo alloy pipe,mouseInconel 600 seamless pipe, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Where can I find it?,Alloy tube is widely used in our daily life, which provides us with great assistance. Application of galvanized pipeIts heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.mouse,Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %Introduction to product knowledge of alloy pipe:Whether I-section steel is ordinary or light, there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, it can only be directly used for members bent in the plane of their web or form lattice stress 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.
