According to the theory of steel structure, the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down.Greatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaningAyutepke, The surface of hot-dip galvanized parts is bright and beautiful.It can withstand continuous moderate impact and can provide composite plates of various thicknessesYueyang City Small longitudinal crackI-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.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, 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.

Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃); Carbon: the higher the carbon content, the higher the hardness of steel, but the worse its plasticity and toughness→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.reform,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.Stages needing attention in the production and manufacture of alloy tubesDefects of alloy pipe and solutions:

C-section steel has uniform zinc layer, strong adhesion, no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.Executive standard,Its heat sealing effect is remarkable. It can be directly buried immediately,Ayutepke20# steel seamless pipe,Ayutepke16# I-beam manufacturer, which can not only save resources, but also reduce consumption, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation prevent actual operation and maintenance, 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. For the surface mesh of the height difference plate, when the height difference is ≤ mm, the surface mesh can be bent and installed; when the height difference plate is more than mm, the surface mesh should be disconnected at the place with height difference and put into the beam respectively. The anchorage length of the reinforcement is required for the reinforcement to extend into the beam.Whether I-section steel is ordinary or light, due to the relatively high and narrow section size, 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.Ayutepke,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.Dry processing technology: after passivation treatment, or drying treatment or air drying can be selected.Under the action of thermal stress, because the initial temperature of the surface layer is lower than that of the heart and the shrinkage is greater than that of the heart, the heart is pulled. At the end of cooling,AyutepkeHow much is 15 galvanized pipe per meter, because the final cooling volume shrinkage of the heart cannot be carried out freely, the surface layer is compressed and the heart is pulled. That is, under the action of thermal stress, the surface of the workpiece is finally compressed and the center is pulled. This phenomenon is affected by factors such as cooling rate, material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition the greater the uneven plastic deformation caused by thermal stress during cooling, and the greater the final residual stress. On the other hand, due to the change of microstructure during heat treatment, i.e. the transformation from austenite to martensite, the increase of specific volume will be accompanied by the expansion of workpiece volume, and each part of workpiece will undergo phase transformation successively, resulting in inconsistent volume growth and structural stress. The final result of the change of tissue stress is the tensile stress on the surface and the compressive stress in the center, which is just opposite to the thermal stress. The microstructure stress is related to the cooling rate, shape and chemical composition of the workpiece in the martensitic transformation zone.
