I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Kesada,Galvanized pipe is often seen in our daily life, especially in some construction sites. This product has the advantage of durability when used. It also has the characteristics of surface gloss, uniform zinc layer and no missing plating. Moreover, the cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings. In addition, this product also has the characteristics of no dripping, strong adhesion breaking the clean Legion and strong corrosion resistance. Even if it is used in some places where the environment is not good, its service life is also very long, and it also has the characteristics of corrosion resistance. The standard anti rust thickness of hot-dip galvanizing can be maintained for more than years without repair. This is used in some suburban environments. However,KesadaHow much is 10 I-beam per meter, in urban or offshore areas,Kesada15CrMo thick wall seamless pipe, standard urban or offshore areas can be maintained for years without repair. The products produced by our company must meet these requirements. Friends who need to order can call us directly.What should we pay attention to in the production of alloy pipeSurinamThe utility model has the advantages that the axial force of the roll is small, the axial movement is small, the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.Stages needing attention in the production and manufacture of alloy tubesWhat is the stainless steel passivation of alloy pipe?

I-beam: national standard * what is the wall thickness of I-beam Quality requirementsb. 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.High value,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.H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel, profiled steel plate, they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type, the flange of H-section steel is widened and the inner and outer surfaces are usually parallel, series and models are complete, which is convenient for settingI-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:

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, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam,Kesada42CrMo thick wall alloy pipe, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Latest quotation,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. According to the purpose, the welded pipe has general purpose and high temperature and high pressure. The pipe used in the latter is often special alloy steel. The problem of shrinkage cracks in the welding process and the mechanical properties of the pipe in the heat affected zone must be considered and solved, and the mechanical properties of the pipe in the heat affected zone will not be greatly changed due to the influence of welding operation.The specification of pass design I-beam is expressed in cm of waist width.

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, 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.Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality. Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, when the extrusion molding is used for mm diameter pipe fittings, the investment of machinery and equipment is less, so the raw material consumption is also very small, and the technology is relatively perfect. Once the tube size is increased
