What is the purpose of flat steelAccording 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.Ulapan,Galvanized pipe features: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.Al Qunaytirah,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. 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, parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.

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. Multi channel cold rolling (cold rolling) process. Cold rolling of steel pipe is carried out on multi roll mill. Stainless steel pipes are rolled with round holes composed of variable cross-section circular grooves and fixed taper.When we carry out different projects, we must use different raw materials, alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know:market price,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. Small longitudinal crack Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time and the waist is parallel to the roll axis.

→ compared with general section steel, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.reform,UlapanHow much is an I-beam,I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:With the development of China&#;s infrastructure, the investment in infrastructure continues to grow; Implement the strategy of western development. Economic construction has entered a new stage, and the demand for welded steel mesh for capital construction such as power, transportation, water conservancy, housing and municipal engineering will increase exponentially.Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %, without high carbon steel and high chromium alloy pipe. The aqueous solution contains % sodium cyanide % ~ % (volume ratio) the solution temperature is ~ ℃,UlapanPrecision cold drawn seamless pipe manufacturer, and the solution time is min.Ulapan,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,Ulapan45# thick wall seamless pipe, cast stones, rubber, polyurethane, etc., it has irreplaceable comprehensive excellent properties.Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);The flange of H-beam is of equal thickness, including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small), a group of vertical rolls must be added for rolling at the same time. Therefore, its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm, which exceeds the welded composite section.
