→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, water supply equipment, or pipeline,Research OfficeAlloy pipe, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.Research OfficeIt bears high internal working pressure.GB No. I-beam is in height, in leg width and in waist thickness.Qingdao City,In order to make the welded pipe have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming process, heat treatment process is often necessary. In addition, the mechanical, physical and chemical properties of aluminum, copper magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.Because the section size of ordinary I-beam and light I-beam is relatively large and narrow, the moment of inertia of the two main shafts on the section is quite different,Research OfficeHow much is 75 galvanized pipe per meter, which limits its application range. I-beam shall be selected according to the requirements of design drawings. In the structural design, the use of I-beam should be reasonably selected according to the mechanical properties, chemical properties, weldability and structural size of I-beam.Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.

After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.There shall be no bending at the welded junction, the free conversion method shall be used for welding as far as possible.The side length of I-beam is small and the height is large, so it can only bear the force in one direction.Sales Department,Research OfficeHow much is 20 steel bars per meter,I-beam is widely used in buildings or other metal structures.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.Alloy pipes can be used for heating (cooling) projects.

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.DiscountMain uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, tractors, railway transportation and other machinery.The smooth of steel pipe is mainly through tension reducing, which is a continuous rolling process of hollow base metal without center and tip. Under the condition of ensuring the capillary welding quality, the whole welded pipe is heated to more than ℃ by the welded pipe tension reduction process, and then rolled to finished pipes with various outer diameters and wall thicknesses by the tension reduction machine ( times in total). The fluid pipes produced by developed countries in the world have adopted the welded pipe smooth process in a large number of boiler pipes. With the development of society, Domestic hot welded pipe has gradually formed a situation to replace smooth pipe.The specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. 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 ~ mm, expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, cross rolling pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.Research Office,I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, etc.H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.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 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.
