→ the two surfaces of the flange are parallel to each other, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.Matansas,In addition, galvanized steel is more expensive than ordinary steel pipes, so installing them requires a lot of financial costs.Difference and application description between H-beam and I-beamWahninen,Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsAfter the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ %, the solution temperature is ~ ℃, and the solution time is min. Then dry.Pass design

Carburizing: carburizing is the process of penetrating carbon atoms into the surface layer of steel. It also makes the low-carbon steel workpiece have the surface layer of high-carbon steel, and then after quenching and low-temperature tempering, the part of the workpiece can maintain the toughness and plasticity of low-carbon steel.In our daily life and work, we can often see a lot of steel products. At the same time, among many steel products, the figure of galvanized pipe is particularly prominent. This is because this kind of pipe will be applied to many engineering construction we often see in our life. There are also countless products processed with this kind of pipe. For example, in the field of mechanical equipment processing we often see,MatansasHow much is a ton of straight welded pipe, the application of galvanized pipe is more frequent. Let&#;s discuss the application scope of this kind of pipe today.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.Statistics,When we carry out different projects, we must use different raw materials, alloy pipe is widely used. In many projects, we will apply it, 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:H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam,MatansasHow much is the price of q355b I-beam per ton, channel steel and angle steel. Small longitudinal crack

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, and it is very easy to manipulate the welding quality.average method,Alloy pipe is a spiral seam seamless steel pipe, which is made of hot-rolled strip steel coil, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit, and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush. When the mesh reinforcement on both sides of the beam is different, and the reinforcement anchorage length is required.Advantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumptionMatansas,Classification introductionGenerally,MatansasHow much is a meter of 3-inch galvanized pipe, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, there is no harm to carry out hot galvanizing in the middle and later stage.Last week, the billet in North China market showed a slight rebound trend. The billet quotation in Tangshan the leading city, rose first and then stabilized in four trading days, with a strong wait-and-see atmosphere in the market. Affected by the almost stagnation of festival procurement, Tangshan billet fell by yuan during the Dragon Boat Festival holiday. On the first day after the festival, although the phase snail is still running at a low level, due to the small billet resources in the market, the steel mills unexpectedly rose, and the billet market rebounded. However, due to the continuous increase of capital pressure and the downturn in the transaction of downstream finished materials, the steel plant has always maintained a cautious wait-and-see attitude to maintain stability.
