Whether I-section steel is ordinary or light, because the section size is relatively high and narrow,DalasHow much is a 30 cm I-beam, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members.At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.Dalas,In view of the current market environment, especially in terms of construction or equipment manufacturing technology, the position of galvanized pipe is still relatively large. It is precisely because of this strong position that we can see this kind of building material in all walks of life, even in the depressed environment of the steel industry, the application situation and utilization rate of this kind of pipe are very high.The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.Valvedditturai,Mixed Scabs are distributed periodically, with large lateral stiffness and strong bending resistance. Under the same specification, H-beam is lighter than I-beam.

I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows: Welded steel mesh is aesthetically pleasing.→ I-beam can be processed into T-beam, which greatly meets the needs of engineering design and manufacturing.Quality inspection report,Function of I-beam: where is I-beam mainly used?Its 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, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation,DalasWhich is a good welded pipe manufacturer, 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.After the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ 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.

Alloy tube is widely used in our daily life, which provides us with great assistance.Interpretation and observation,Stages needing attention in the production and manufacture of alloy tubes Stair step plate (stair step plate) is a kind of stair used for platform with steel bar mesh. According to the installation method, it generally has two types: welding fixation and bolt (composition: head and screw). It is directly welded to the keel and does not need the side plate with step plate. It is relatively economical and durable but it is not easy to disassemble, Thickened side plates are required on both sides of the bolted tread plate and holes are drilled on the side plates.H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel, profiled steel plate, etc.). Due to the reasonable section shape, they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type, the flange of H-section steel is widened, and the inner and outer surfaces are usually parallel, so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable, series and models are complete, which is convenient for settingDalas,→ wide flange and large lateral stiffness. Strong bending resistance.All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape. Small longitudinal crack
