The high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment, the surface layer of parts must be removed to remove waste. At a higher temperature, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.a. In the forming process, the thick steel plate has uniform deformation, 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,AquintelWhat is the general elongation of reinforcement, 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.Aquintel,The surface of cold galvanized layer is smooth dense and uniform. It has good mechanical properties and corrosion resistance. The consumption of hot-dip galvanized coating is between % - %. The galvanizing process is complex, surface coating and double-sided coating is different but the thickness of single-sided coating, there is still a big gap in the production technology of C-section steel between China and foreign countries.Aqtobe,I-beam: national standard * what is the wall thickness of I-beamHeating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);Some applications of I-beam:

It can withstand continuous moderate impact and can provide composite plates of various thicknessesWelded steel pipe, also known as welded pipe, is a seamless steel pipe made of thick steel plate or hot-rolled strip by electric welding after coiling and forming,Aquintel65. How many kilograms per meter of welded pipe, generally with a fixed length of m. Welded steel pipe has the advantages of simple production and processing process, high production efficiency, many types, specifications and models, and less investment in machinery and equipment projects, but the general compressive strength is less than that of seamless pipe. 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.Trustworthy,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, 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.After the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution,Aquintel12CrMo alloy pipe, ~ 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.The specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. The types of I-beam include hot-rolled ordinary I-beam Light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~ mm, expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, cross rolling pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.

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, 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:target,What is the stainless steel passivation of alloy pipe? The reinforcement on both sides of the inverted beam extends into the beam respectively, and the anchorage length of the reinforcement is the same as that of the reinforcement, without hook.Due to the unique performance of I-beam,Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %, the solution temperature is ~ ℃, and the solution time is min.It is often asked that the shape of I-beam is similar to that of H-beam. What is the difference between them? Many people can&#;t explain it in detail. Here is a detailed answer for you: many people think that I-beam is a domestic name and H-beam is a foreign name. In fact, this cognition is wrong. H-beam and I-beam are different in shape!Introduction to product knowledge of alloy pipe:
