H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter 'H'. The flange of hot rolled H-beam is wider than that of I-beam, with large lateral stiffness and strong bending resistance. Under the same specification, H-beam is lighter than I-beam.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.San miglito,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.Application characteristics of I-beam:Guaimaro,The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power,San miglitoHow much is 16# I-beam, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.Alloy pipe is a kind of seamless steel pipe. Alloy pipe is divided into structural seamless pipe and high-pressure heat-resistant alloy pipe. It is mainly different from the production standard and industry of alloy pipe. Annealing and tempering of alloy pipe changes its mechanical properties. Meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipe, its utilization value is higher the chemical composition of alloy pipe contains more Cr, and its performance of high temperature resistance, low temperature resistance and corrosion resistance. Ordinary carbon seamless tubes do not contain alloy components or have few alloy components. Alloy tubes are widely used in petroleum,San miglito20# thick wall seamless pipe, aerospace, chemical industry, electric power boiler and other industries because the mechanical properties of alloy tubes change and are easy to adjust.

The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -, rectangular section and slightly pure edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate.First, we can clean the outer surface of the welded pipe with solvent or emulsion. This method is very effective for cleaning the oil stain, dust and other organic matters on the surface of the welded pipe.The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -, rectangular section and slightly pure edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate.Free consultation,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 sleeves of the section is quite different, I-beam has no specific composition and performance series.Alloy tube is widely used in our daily life, which provides us with great assistance. So what industries are alloy tubes applied to? Let&#;s follow the steps of all manufacturers and have a look together:

What is the stainless steel passivation of alloy pipe?Process inspection, Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, low cost,San miglitoA335p11 American standard high pressure alloy pipe, easy maintenance, durable economic development and convenient product specification transformation. For example, the production of large diameter must be grooved pipe, elbow and similar products. You only need to add some spare parts. The expansion method of hot push can be used to process and manufacture large-diameter, thick wall and thin alloy steel pipes, and can not exceed the working capacity of thick wall pipes of machinery and equipment. The weight of seamless pipe is light, and its weight is only one fifth of that of anti steel.The utility model has the advantages that the axial force of the roll is small, the axial movement is small, and the working slope is not required,San miglito Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis.b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.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.
