Using alloy pipe to produce ring parts can improve the utilization rate of raw materials simplify the production and manufacturing process, and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays, seamless steel pipe has been widely used to produce hydraulic jack sleeve.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, I-beam can also adopt special rolling method.Komapa, Welded steel mesh, a new form of reinforcement, is especially suitable for large-area concrete engineering.I-beam, also known as universal beam,Komapa200 welded pipe more than 1m, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Naqadeh, Miscellaneous scabSo why is the alloy pipe easy to rust after being pickled and passivated by the software?Stages needing attention in the production and manufacture of alloy tubes

The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.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.According to the theory of steel structure, the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down.Promise and keep promise,I-beam is widely usedPass designC - section steel is reliable and stable in stress, can be accurately positioned, and is resistant to impact and vibration Moreover, it has good versatility and combination,KomapaHow many inches is welded pipe 219,KomapaHow much is 114 seamless pipe per ton, and has a variety of C-section steel and size selection to ensure its flexibility

Performance parameters and application scope of I-beamDirect material, the higher the hardness of steel, but the worse its plasticity and toughnessI-beam whether ordinary or light, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.Komapa,Passivation treatment operation of alloy pipe→ wide flange and large lateral stiffness. Strong bending resistance.b. 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
