The import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number, I-beam has no specific composition and performance series.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, aerospace, chemical industry, electric power, boiler and other industries because the mechanical properties of alloy tubes change and are easy to adjust.Dordrecht, General carbon steel wire sleeve (GB / t- is a steel pipe used to protect wires in electrical installation projects such as industrial and civil buildings and installation of machinery and equipment.Dry processing technology: after passivation treatment parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.Santa AnaThe 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,DordrechtHow many kilograms per meter of welded pipe,The wear resistance, fracture toughness, impact toughness and bending strength under different process conditions were compared, and then the heat treatment process of GCrMo was determined. Development and application of ZYS- bearing damping and antirust oil. Bearing is a new type of multial damping and antirust oil. It takes refined mineral oil as the base oil and is equipped with various additives such as antirust and antifriction. Through comparison test, matching test with lubricating grease and user test, it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance.Function of I-beam: where is I-beam mainly used?

I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.On the other hand, when the steel structure changes during heat treatment, that is, austenite transforms into martensite, the increase of specific volume will be accompanied by the expansion of workpiece volume, and each part of workpiece will undergo phase transformation successively, resulting in inconsistent volume growth and structural stress. Due to the change of tissue stress, the tensile stress on the surface and the compressive stress in the heart are just opposite to the thermal stress. The magnitude of microstructure stress is related to the cooling rate, shape and chemical composition of martensitic transformation zone materials.The system is mainly composed of control box, finishing roller,Heating surface pipes finishing unit and straightening unit.Honest management, economizers, superheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)Application scope of alloy pipeAs shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, which makes the outer flange thin and the inner flange thick. Therefore, 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.

Stages needing attention in the production and manufacture of alloy tubesnew product,DordrechtSA213T91 alloy pipe,DordrechtHow much is the quoted price of I-beam per ton,I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.Characteristics and application of galvanized pipeStages needing attention in the production and manufacture of alloy tubesDordrecht, Small longitudinal crackThe system is mainly composed of control box, finishing roller, pre leveling unit, finishing unit and straightening unit. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.
