Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.Granby, The cold-rolled stainless steel pipe has the advantages of large yield coefficient, no expansion, bending and so on. In order to reach the health grade standard of stainless steel pipeline, the pipeline after cold rolling must undergo bright annealing, demagnetization, pickling, calibration and other procedures.The section of I-beam has good straight pressure and tensile resistance, but the section size cannot resist torsion because the wing plate is too narrow. On the contrary, H steel has its own advantages and disadvantages.Bayawan City, Small longitudinal crackAfter determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes and connect the switching power supply, If the current flows from the positive stage to the negative stage a layer of zinc is deposited in the pipe.The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.

Remove defective pipes within the allowable length.Check whether the manufacturer&#;s qualification, business license, organization code certificate, tax registration certificate, production and operation license and other qualification materials are complete. Look at the case, investigate the supplier&#;s performance and the projects served in the past. Whether there is a self built logistics fleet or not, choosing a service provider with a self built logistics fleet can reduce the transportation cost, and more importantly, ensure the timeliness of delivery. After sales service, and timely solve quality problems in arrival acceptance and subsequent use. Check whether the quality assurance materials such as product quality certificate, material specification and warranty are complete. Check the appearance of the welded pipe, the surface is smooth and flat, the weld is dense, without burr, oil stain, corrosion, extrusion deformation and flat cross section. Use a micrometer to check whether the outer diameter and wall thickness of the welded pipe meet the requirements, and the standard wall thickness deviation shall not exceed % - %. NDT shall be carried out for welded pipe with flaw detector. Conduct bending tensile strength test according to the requirements, bend the welded pipe for degrees,I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height,GranbyGh4105 alloy pipe, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.Greatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaning

The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -,Methods of exerting efficiency in application of C-section steel It has a thick and dense pure zinc layer covered on the steel surface, which can prevent the steel substrate from touching with any corrosion solution and maintain the steel substrate from corrosion. In general atmosphere, which is difficult to dissolve in water, so it plays a certain maintenance effect on steel matrix. If zinc oxide and other components in the atmosphere form insoluble zinc salts,GranbyCustom welded pipe, the anti-corrosion effect is more ideal.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.Granby,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 ~,GranbyWill reinforced concrete rise or fall in 2021, 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.b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.Ways to obtain surface compressive stress characteristics of alloy tubes
