Pak KobeHow much is the I-beam of 28Fast delivery

I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.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., 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.Pak Kobe,Filling: welded pipe is welded by electric welding of hot-rolled strip steel, 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.Kishoganji,So why is the alloy pipe easy to rust after being pickled and passivated by the software?Some applications of I-beam:Plan option : Martensitic chromium alloy pipe,

The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.The laying of reinforcement mesh can speed up the construction speed and shorten the construction period. In order to reduce the impact of construction on road traffic, the reinforcement and maintenance works of the two bridges are expected to be completed in the middle of next month.Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.Word of mouth recommendation,After the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ %, the solution temperature is ~ ℃, and the solution time is min. Then dry.Alloy pipe is a spiral seam seamless steel pipe,Pak KobeHow much is a 32 inch galvanized pipe, which is made of hot-rolled strip steel coil, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit, and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush.According 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.

Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementThe cost is reasonable,As shown in the name, generally :, which makes the outer flange thin and the inner flange thick. Therefore,Pak Kobe12CrMo alloy pipe, the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market the structure of the I-beam has determined its torsional performance.The second is the control of welding materials to ensure that the welding materials purchased are from formal channels, with quality assurance certificate and certificate, which meet the process requirements; The recovery of welding rod head shall be strictly controlled to ensure the flow direction and dosage; Welding materials shall be baked in strict accordance with the process, and the amount of one-time distribution shall not exceed half a day.→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.Pak Kobe,Pak Kobe15CrMoG seamless pipe factory, Small longitudinal crackAlloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, when the circular cross section bears the internal or external axial working pressure the bearing force is more symmetrical. Therefore, most seamless steel pipes are round steel pipes. Remove defective pipes within the allowable length.
