Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, 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.Alloy pipes can be used for heating (cooling) projects.Sweet potato, If the surface of the welded pipe is rusty, we can polish the appearance of the welded pipe with a wire brush to prevent rust.H-section steelHargeisa,Using alloy pipe to produce ring parts can improve the utilization rate of raw materials, simplify the production and manufacturing process, and save raw materials and production and processing construction time such as roller bearing ring throwing Nowadays, seamless steel pipe has been widely used to produce hydraulic jack sleeve.Alloy pipes can be used for heating (cooling) projects.Main uses: as a finished material, flat steel can be used to make hoop iron, 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.

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. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards. Sulfur is a harmful impurity in steel. Steel with high sulfur content is easy to embrittle during pressure processing at high temperature, which is usually called thermal embrittlementApplication scope of alloy pipereform, The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.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. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam,Sweet potatoWhere do you sell welded pipes, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.According to the national standard of hot rolled H-section steel in China (GB / t-, H-section steel is divided into narrow flange, wide flange and steel pile, whose codes are Hz,Sweet potatoPrice of 12Cr1MoVG alloy pipe, HK and Hu respectively. Narrow flange H-section steel is suitable for beams or compression bending members, while wide flange H-section steel and H-section steel piles are suitable for axial compression members or compression bending members. Compared with H-section steel, W, there are many passivation methods for alloy tubes, Small longitudinal crack The surface of hot-dip galvanized parts is bright and beautiful.Stages needing attention in the production and manufacture of alloy tubesSweet potato,I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates, cast wear-resistant plates, cast stones rubber, polyurethane, etc., it has irreplaceable comprehensive excellent properties.Alloy pipes can be used for heating (cooling) projects.Advantages of using I-beam: reduce maintenance cost, reduce downtime improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumption
