When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, 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:I-beam: national standard * what is the wall thickness of I-beamSaint Vicente, Manganese: it can improve the strength of steel, weaken and eliminate the adverse effects of sulfur, and improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical propertiesThe side length of I-beam is small and the height is large, so it can only bear the force in one direction.Cutral-Co,Passivation treatment operation of alloy pipeI-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,Saint Vicentetwo hundred × How much is 100 I-beam per meter, cast stones, rubber, polyurethane, etc.,Saint VicenteAlloy pipe 12Cr1MoVG price, it has irreplaceable comprehensive excellent properties.H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel, profiled steel plate, 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 setting

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.Classification by production methodWith the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, which is easy to lose stability for load-bearing columns.Inspection standard,Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.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, expressed as No. ~ No. light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, 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.I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, huangte, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, etc.

Greatly reduce the environmental pollution caused by abrasion, damage and blanking,Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %The multi-al combination of reinforcement mesh welding machine and reinforcement mesh row welding machine based on PLC basic control. At present, the full-automatic mesh welding machine has the characteristics of simple operation, high control precision and easy to master the process of high-speed continuous welding.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.Saint Vicente, Remove defective pipes within the allowable length.What are the uses of I-beam?The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid, sodium cyanide, etc., which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.
