It is widely used in various fields of national economic construction, such as buildings, bridges, power stations, oil drilling platforms, vehicles, subways, steel structure plants and large warehousesApplication characteristics of I-beamDelmas, Spiral seam high-frequency welded steel pipe (sy- for pressure fluid transportation is a spiral seam high-frequency welded steel pipe used for pressure fluid transportation, which takes hot-rolled steel strip as pipe blank, which is convenient for welding and processing; After various strict and scientific inspections and tests, the application is safe and reliable the diameter of steel pipe is large, the transportation efficiency is high, and the investment in laying pipeline can be saved. It is mainly used for laying pipelines for transporting oil, natural gas, etc.Application characteristics of I-beamGuapiles,The utility model has the advantages that the axial force of the roll is small, the axial movement is small,Delmas42CrMo thick wall alloy pipe, the working inclined plane is not required, the pass occupies a small length of the roll body,Delmas200 welded pipe more than 1m, and more passes can be matched under the condition of a certain length of the roll body.Requirements of alloy tubes for low and medium pressure boilersThe wear resistance, fracture toughness impact toughness and bending strength under different process conditions were compared,DelmasHow much is cold drawn welded pipe, 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.

GB No. I-beam is in height, in leg width and in waist thickness.They are not affected by surrounding factors and processes, including corrosion.The shape of I-beam is similar to that of H-beam. What is the difference between them?middleman,Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementThe utility model has the advantages that the axial force of the roll is small, and the working slope is not required, The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.

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.build,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, etc., it has irreplaceable comprehensive excellent properties.Compared with manual binding, welded steel mesh can reduce the occurrence of cracks by more than %. The use of reinforcement mesh can make the project construction faster. As long as the reinforcement mesh is laid as required, the concrete can be poured, eliminating the links of reinforcement on-site cutting, placing one by one and binding. It can save % - % of working hours, greatly accelerate the construction progress and shorten the construction cycle.Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Delmas,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.I-beam is widely usedI-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, 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.
