H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter 'H'. The flange of hot rolled H-beam is wider than that of I-beam, with large lateral stiffness and strong bending resistance. Under the same specification, H-beam is lighter than I-beam.Requirements of alloy tubes for low and medium pressure boilersPansosInstalling the pipe structure means the complexity of some elements.The 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.Jaen, The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge. Small longitudinal cracka. 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.

Application characteristics of I-beam Spray is OK. This method can not only completely remove rust, oxide and dirt, but also the welded pipe will be affected by abrasive impact and friction, resulting in the average roughness of the welded pipe.The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, expressed as No. ~ No.,PansosCold drawn welded pipe manufacturer, and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.Direct material,Introduction to product knowledge of alloy pipe: Peak crackH-section steel

Ways to obtain surface compressive stress characteristics of alloy tubesLet's see, strong adhesion smooth surface, no zinc scar no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, corrosion resistance and durability. It is a kind of stronger protection.Packaging: Welding nets are generally packaged in paper (mostly gray white, yellow, etc.), some similar to welding wire diameter welding nets, agriculture, construction, transportation,PansosWhat is the general elongation of reinforcement,PansosQ345B welded pipe manufacturer, mining and other industries. Such as machine shields, animal fences, flower and tree fences, window fences, aisle fences, poultry cages, baskets and decorations.Main uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery.Pansos, the interval is min.d. All machines and equipment in a production line can connect with the software of the computer data collection system to complete the timely transmission of data information, and the performance parameters in the production process are monitored by the central control room.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.
