I-beam has successfully solved the problem of serious equipment wear in many industries.San Pablo

Ways to obtain surface compressive stress characteristics of alloy tubesDue to the unique performance of I-beam,From the current scope of use,San Pablo Price of No. 18 I-beam, it is mainly widely used in glass curtain wall, power tower, communication power grid and other industries. In recent years, which is enough to show that the quality of galvanized pipe is very good, and it also brings a lot of convenience in the process of use, so it can be used better.However,San Pablo How much is 80 galvanized pipe per meter, what we need to do now is to improve the production technology level of China&#;s production process of C-section steel, and step up the formulation of relevant industry standards and inspection standards. C-section steel manufacturers should keep close contact with truck manufacturers and communicate more. In this way, it is more conducive for C-section steel manufacturers to produce C-section steel products suitable for truck industry.Sogamoso,Greatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaningI-beam is mainly used in building structure, mechanical equipment and vehicle manufacturing.Carburizing: carburizing is the process of penetrating carbon atoms into the surface layer of steel. It also makes the low-carbon steel workpiece have the surface layer of high-carbon steel, and then after quenching and low-temperature tempering, the part of the workpiece can maintain the toughness and plasticity of low-carbon steel.

I-beam is widely used 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 the surface of zinc layer forms a thin and dense zinc oxide layer, 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, the anti-corrosion effect is more ideal.Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %, without high carbon steel and high chromium alloy pipe. The aqueous solution contains % sodium cyanide % ~ % (volume ratio), the solution temperature is ~ ℃, and the solution time is min.Installation material list,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.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 -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.

Remove defective pipes within the allowable length.install,I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates, cast wear-resistant plates, cast stones, rubber, polyurethane, it has irreplaceable comprehensive excellent properties.Seamless pipe production processWhat are the uses of I-beam?San Pablo When it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering, mining and other industries to meet the provisions of cold, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.Classification introductionAt present, there is still a big gap in the production technology of C-section steel between China and foreign countries.
