Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, water supply equipment, or pipeline, alloy steel pipe stimulates important effects.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.Otrukovich,Galvanized pipe has excellent corrosion resistance. Compared with traditional steel its application life is longer. Secondly, this kind of pipe has strong resistance to baking. In case of critical situation, it will not lead to the collapse of building structure in a short time. In addition, this kind of pipe also has a practical advantage, that is, it is more convenient and lighter when carrying out the construction and installation. The operators save time and labor when carrying out the construction, and the operation efficiency has been greatly strengthened. In this regard, it is not difficult to understand why the galvanized pipe is so favored by various construction units.I-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam,Because all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used. The inner and outer sides of the flange of the I-beam are parallel or close to parallel, and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of I-beam is smaller than that of ordinary I-beam with the same height of web, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam.Introduction to product knowledge of alloy pipe:What is the stainless steel passivation of alloy pipe?

Application characteristics of I-beam Material requirementsThe utility model has the advantages that the axial force of the roll is small,Otrukovich20CrMnTi alloy pipe, the axial movement is small the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.technological innovation,→ the two surfaces of the flange are parallel to each other, making it easy to connect, process and install.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.→ the two surfaces of the flange are parallel to each other, making it easy to connect, process and install.

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.,OtrukovichPrice list of 18# I-beam,OtrukovichPrice of 1Cr5Mo alloy pipe, 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.Quality management,Application characteristics of I-beam: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.In order to make the steel pipe workpiece have the required mechanical, physical and chemical properties, heat treatment process is often essential. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, aluminum, copper, magnesium, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different service properties.Otrukovich,The shape of I-beam is similar to that of H-beam. What is the difference between them? Peak crackWhen selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.
