I-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,The electric welding reinforcement mesh can reduce the damage and consumption to the reinforcement processing process. According to statistics so its application range is very limited. I-beams are widely used in buildings and other metal structures.I-beam is widely usedsausage, after deducting the steel consumption increased by unit lapping, it can also save about % of the steel. After it is transported to the site according to the construction degree of the project, which saves the site and increases the management level of the site. At the same time, it can also solve the problems of noise pollution caused by straightening reinforcement.At the same height, light I-beam has narrower legs, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.Hamina,GB No. I-beam is in height, in leg width and in waist thickness.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. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.

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. Material requirements Peak crackDiscount,Main uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles,sausage16Mn seamless pipe manufacturer, tractors, railway transportation and other machinery.Because the section size of ordinary I-beam and light I-beam is relatively large and narrow, 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.Introduction to product knowledge of alloy pipe:

I-beam: national standard * what is the wall thickness of I-beamExecutive standard,According to the theory of steel structure, the I-beam flange should be stressed, that is,sausageHow much is 16 steel bar, the I-beam should be standing rather than lying down.The fourth is the welding process method to ensure the strict implementation of the special operation method of galvanized pipe. The welding process includes pre welding groove inspection, control of welding process parameters and operation methods, post welding appearance quality inspection, and post welding nondestructive testing if necessary. Control the welding level and the amount of welding materials at each crossing.All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.sausage,X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids,sausageHow much is an I-beam, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than % Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, low cost, 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.
