H-section steel is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'. There is no slope on the inner side of the two outer edges of H-section steel, which is straight. This makes the welding and splicing of H-section steel simpler than I-section steel,PerikoHow much is 18 I-beam, better mechanical properties per unit weight, and can save a lot of materials and construction time.Ways to obtain surface compressive stress characteristics of alloy tubesPerikoFilling: welded pipe is welded by electric welding of hot-rolled strip steel, so its influence was not as high as that of seamless steel pipe.→ the two surfaces of the flange are parallel to each other, making it easy to connect, process and install.Cambodia,Alloy pipes can be used for heating (cooling) projects.H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel, profiled steel plate, etc.). Due to the reasonable section shape, 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,PerikoHow much is a meter of DN32 galvanized pipe, series and models are complete, which is convenient for settingPass design

c. quality inspection is carried out for alloy pipes, so that the whole process of steel pipe processing is under reasonable inspection and supervision, and the product quality is reasonably guaranteed.Steel pipes can be classified by their models: Peak crackWhere is it, Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, low cost, easy maintenance, durable economic development and convenient product specification transformation. For example, elbow and similar products. You only need to add some spare parts. The expansion method of hot push can be used to process and manufacture large-diameter, thick wall and thin alloy steel pipes, and can not exceed the working capacity of thick wall pipes of machinery and equipment.Alloy pipe is a kind of seamless steel pipe. Alloy pipe is divided into structural seamless pipe and high-pressure heat-resistant alloy pipe. It is mainly different from the production standard and industry of alloy pipe. Annealing and tempering of alloy pipe changes its mechanical properties. Meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipe, its utilization value is higher, the chemical composition of alloy pipe contains more Cr,PerikoGH3044 superalloy tube, and its performance of high temperature resistance, aerospace, chemical industry, electric power, boiler and other industries because the mechanical properties of alloy tubes change and are easy to adjust.I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRC

Welded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, due to the inconsistency of cooling speed and time between the surface and the core the temperature difference will be formed, which will lead to uneven volume expansion and contraction and produce stress, that is, thermal stress.target,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. The vertical of the processed reinforcement bar shall be divided into small sections as required.X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.Periko,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. Remove defective pipes within the allowable length.The system is mainly composed of control box, finishing roller, pre leveling unit, finishing unit and straightening unit.
