I-beam has wide flange, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.Advantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumptionVlaschatz,Thin wall steel pipe, thick wall steel pipe.Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsMingguru Province,Ways to obtain surface compressive stress characteristics of alloy tubesUsing 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.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.

Judged as failing.Welded steel pipe, is a seamless steel pipe made of thick steel plate or hot-rolled strip by electric welding after coiling and forming, generally with a fixed length of m. Welded steel pipe has the advantages of simple production and processing process, high production efficiency, many types specifications and models, and less investment in machinery and equipment projects, but the general compressive strength is less than that of seamless pipe. Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy radial wheel. After one or several solutions, there can also be a variety of methods for the whole process of hollow thick wall rotating body products. Products manufactured by high-precision processing method have excellent physical properties, specification scope, mold shell and software requirements, which are very simple, very easy to be replaced, and relatively low product cost. The processing time is not long enough, the processing capacity is not high, the total length of processing pipeline is limited, and the size of machinery and equipment is generally short.market,Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.Classification introductionThe 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., 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.

In order to make the steel pipe workpiece have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming processes, 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, the heat treatment of steel is the main content of metal heat treatment. In addition, aluminum, copper, magnesium, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different service properties.Installation materials,VlaschatzSeamless pipe real-time price,I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure. Seismic and cracking performance the longitudinal and transverse bars of the welded reinforcement mesh form a network structure, so it has good bonding and anchorage with the concrete, which obviously shows the seismic cracking performance of the reinforced concrete structure. According to the actual test,Vlaschatza106gr. B) seamless pipe, the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh. It greatly reduces the unnecessary cost generated manually in the construction and shortens the construction period. The use of reinforcement mesh is simple and convenient, and the reinforcement mesh is convenient for transportation.All the cracks occur at -mm away from the edge below the alloy pipe,I-beam can only be used for beam while H-beam can be used for load-bearing column of structure.Dry processing technology: after passivation treatment, parts shall be dried with air compression or hot gas,VlaschatzAlloy pipe 12Cr1MoVG, or drying treatment or air drying can be selected.Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.
