What should we pay attention to in the production of alloy pipeRequirements of alloy tubes for low and medium pressure boilersSinchi ,Generally in terms of strength, toughness and mechanical properties. There are many differences. Hot dip galvanized pipe: the coil formed by welding the square pipe with steel plate or steel strip is placed in the galvanized tank on the basis of the square pipe to form a series of chemical reactions on the square pipe. The production process of hot-dip galvanized steel pipe is simple, the production efficiency is very high, which is suitable for the production of small galvanized steel pipe plants. However, redox method and characteristic table.The side length of I-beam is small and the height is large,Sinchi Large diameter 15CrMoG alloy pipe, so it can only bear the force in one direction.CoronellAt present, there is still a big gap in the production technology of C-section steel between China and foreign countries.The utility model has the advantages that the axial force of the roll is small, the axial movement is small, the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.What should we pay attention to in the production of alloy pipe

I-beam Tungsten; can improve the red hardness and thermal strength of steel, and can improve the wear resistance of steelStages needing attention in the production and manufacture of alloy tubesStatistics,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.→ compared with general section steel, 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.Alloy pipes can be used for heating (cooling) projects.

Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);Installation conditions, Small longitudinal crack Simple section steel pipe -- circular steel pipe square steel pipe,Sinchi 12Cr1MoVG high pressure alloy pipe, oval steel pipe, triangular steel pipe, hexagonal steel pipe, rhombic steel pipe octagonal steel pipe, semi-circular steel pipe, others.Application scope of alloy pipeSinchi ,Welded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, and their metal properties are controlled by changing the metallographic structure on the surface or inside of the material. During the heating and cooling process of structural welded steel pipe workpiece, due to the inconsistency of cooling speed and time between the surface and the core, the temperature difference will be formed, which will lead to uneven volume expansion and contraction and produce stress, that is, thermal stress.The import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number, I-beam has no specific composition and performance series.When we carry out different projects, 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:
