I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V,Stretch punching by steel plate equipment; The main purpose is to be used in the structure of scaffold.Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.Bakersfield,Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %Determined by the shape, the section modulus moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.I-beam, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.

As shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, which makes the outer flange thin and the inner flange thick. Therefore, the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance. Seamless tube has high elasticity, can be reused on mechanical equipment, no memory, no deformation, anti-static.Because alloy pipe is a very unique pipe fitting, we must use appropriate methods to carry out installation in the case of installation, when installing alloy pipes, we will use some flanges and elbows to fix them, when we carry out use, we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.Free consultation,Greatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaningThe crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.Plan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min.

The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power and the power is large, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.Quality inspection report,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. 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.During the heating and cooling process of structural welded pipe workpiece, due to the inconsistent cooling speed and time of surface layer and core layer, the temperature difference will be formed, resulting in uneven volume expansion and contraction, resulting in stress, namely thermal stress. Under the action of thermal stress, the starting temperature of the surface layer is lower than that of the core layer, and the shrinkage is greater than that of the core layer, the surface layer is compressed and the core is stretched because the cooling volume contraction of the core cannot be carried out freely. That is, under the action of thermal stress, the surface of the workpiece is compressed and the core is pulled.The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid, sodium cyanide, etc., which has strong corrosion and reduction,SaquezHow much is DN32 galvanized pipe per meter,SaquezHow much is 30 I-beam per meter, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.SaquezAll the cracks occur at -mm away from the edge below the alloy pipe, showing a 'high mountain' shape.Application characteristics of I-beam: Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time and the macroeconomic orientation is vertical to the cold rolling orientation, and the waist has an included angle with the horizontal axis.
