due to the relatively high and narrow section size, 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.Advantages of using I-beam: reduce maintenance cost, improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumptionLincolnSpecial shaped pipe: square pipe, rectangular pipe, cap pipe, steel pipe for hollow rubber steel doors and windows welded by general carbon structure steel and Mn steel strip, mainly used as agricultural machinery components, steel windows and doors etc.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.Mostoles,LincolnQ345 straight seam welded pipe,Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsApplication characteristics of I-beamGenerally, the process of pickling and passivation will be carried out for alloy pipes,Lincoln15CrMo alloy pipe factory, 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.

→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.There are several ways to clean galvanized pipesThe delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.offer, Peak crackWays to obtain surface compressive stress characteristics of alloy tubesAfter determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.

Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %, without high carbon steel and high chromium alloy pipe. The aqueous solution contains % sodium cyanide % ~ % (volume ratio), the solution temperature is ~ ℃, and the solution time is min.Application process,LincolnHow much is a meter of 2-inch galvanized pipe,Xhy- series high hardness alloy I-beam; Undertake drawings and process wear-resistant pipes（ Φ ≥mm）； Undertake the processing and production of vulnerable parts of cement machinery; Welding technology consultation and service; The wear-resistant layer of alloy wear-resistant plate of high chromium heap welding flux cored wire series is mainly high chromium, as well as manganese, molybdenum, niobium, francium and other components. The alloy carbide formed has strong stability at high temperature. Silicon; it can improve the hardness of steel but the plasticity and toughness decrease. Electrical steel contains a certain amount of silicon, which can improve the soft magnetic propertiesWhat should we pay attention to in the production of alloy pipeLincoln,Application characteristics of I-beam:H-section steelMixed Scabs are distributed periodically
