As shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, which makes the outer flange thin and the inner flange thick. Therefore, the section characteristics of I-beam in the two main planes are very different,Y.S.LQ345 straight seam welded pipe, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance.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.Y.S.L,From the comparison of the monthly summary apparent consumption data information of galvanized pipe and the real estate sales data information from to this year, they show the consistency of height width ratio, which not only shows a positive correlation in the overall new trend, but also significantly conforms to the fluctuation direction of the monthly development trend.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, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.Comoros,Y.S.LHow much is the price of I-beam per ton,The utility model has the advantages that the axial force of the roll is small, the axial movement is small,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, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.I-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.

Passivation treatment operation of alloy pipe Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility,Y.S.LWholesale quotation of I-beam, so it is flexible. Galvanized pipe is widely used in architecture. This product must have been seen by everyone. However, there are many types of it. When you buy it, you should also find out which one you need. The reason why it is favored by everyone in the market is inseparable from its advantages. Next, Xiaobian will lead you to see the advantages of galvanized pipe.Welded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, due to the inconsistency of cooling speed and time between the surface and the core the temperature difference will be formed, that is which will lead to uneven volume expansion and contraction and produce stress, thermal stress.quality index,The shape of I-beam is similar to that of H-beam. What is the difference between them?The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlement

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, polyurethane, etc., it has irreplaceable comprehensive excellent properties.original,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, the use of I-beam should be reasonably selected according to the mechanical properties, chemical properties weldability and structural size of I-beam.The grid spacing size and number of reinforcement of electric welding reinforcement mesh are correct, which overcomes the phenomenon of large spacing size error and missing binding and buckle of binding quality caused by manual placement of reinforcement in traditional manual binding. The welded steel mesh has high strength and good elasticity. When pouring concrete, the steel bar is not easy to be partially bent and does not change. Because it is considered that the longitudinal and transverse steel bars are spot welded into a mesh structure, so as to achieve the goal of side-by-side average stress and bonding anchor.Precision cold rolling of small and medium-sized bearing sleeves with alloy tubes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the development of high quality cold drawn bearing steel pipe and its application in bearing. Precision cold rolling of small and medium-sized bearing sleeves with bearing steel pipes can greatly improve material utilization,Alloy tube is widely used in our daily life, which provides us with great assistance. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.I-beam: national standard * what is the wall thickness of I-beam
