Difference and application description between H-beam and I-beamGreatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaningSanta Barbara, and the demand for welded steel mesh for capital construction such as power the investment in infrastructure continues to grow; Implement the strategy of western development. Economic construction has entered a new stage,Santa BarbaraCustom welded pipe, transportation, water conservancy, housing and municipal engineering will increase exponentially. Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis.Sivednica,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. Peak crack Small longitudinal crack

The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels. When the end span plate is connected with the concrete beam for structural reinforcement, the length of the surface mesh reinforcement extending into the beam shall not be less than d. When the beam width is small,Santa BarbaraHow much is I-beam per square meter, the extended reinforcement shall be bent . When the perimeter of the floor is poured integrally with the concrete beam or wall, the length of the surface mesh reinforcement extending into the beam shall not be less than the anchorage length of the small reinforcement required by the standard (without transverse reinforcement), when the beam width is small, the extended reinforcement shall be bent.The section of I-beam has good straight pressure and tensile resistance, H steel has its own advantages and disadvantages.build,What is the stainless steel passivation of alloy pipe?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, and the macroeconomic orientation is vertical to the cold rolling orientation so its application range is very limited. I-beams are widely used in buildings and other metal structures.All the cracks occur at -mm away from the edge below the alloy pipe, showing a 'high mountain' shape.

When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know:build,Plan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min. Pickling: if the material cannot be removed after cleaning, pickling will be selected. Pickling of galvanized pipe is divided into chemical and electrolytic. How to prevent white rust of galvanized seamless steel pipe? It has a certain anti-corrosion effect on the pipeline.Defects of alloy pipe and solutions:Santa Barbara,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, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas,Santa BarbaraGh3128 alloy pipe, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.It can withstand continuous moderate impact and can provide composite plates of various thicknesses
