Introduction to product knowledge of alloy pipe: Remove defective pipes within the allowable length.Port Natales,Filling: welded pipe is welded by electric welding of hot-rolled strip steel, so its influence was not as high as that of seamless steel pipe.The specification of pass design I-beam is expressed in cm of waist width. For example,Port NatalesHow much is the I-beam for a ton, 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,Stages needing attention in the production and manufacture of alloy tubesI-beam: national standard * what is the wall thickness of I-beam→ under the same section load the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.

Miscellaneous scabFirst, the wall thickness of high-quality and smooth steel is particularly thick. Because the thicker the wall thickness of the product, the higher the economy and practicability. The thinner the wall thickness, the greater the processing cost and opportunity, and the higher the resource cost. Secondly, the process of smooth steel also determines its limitations. Generally, smooth steel has low precision, uneven wall thickness low brightness inside and outside the pipe, high length cost,Port NatalesWhere are many manufacturers of welded pipes, pockmarks in the internal appearance, and black spots are not easy to remove. Again, the inspection and shaping need to be processed offline. Therefore, it has its advantages in high pressure, high strength and mechanical structure materials. In the process of use, we will gradually find out. In fact, seamless pipe has also entered the market in recent years. With the growth of market demand, the advantages of seamless pipe have also been stimulated. But there are also many fakes and fake products on the market. Be careful when you choose.The alloy tube can be hardened by induction heating, so it has excellent rolling fatigue characteristics and corrosion resistance. Therefore, this kind of steel has been widely used as the material of rolling mill flap ball screw in rolling mill manufacturers. In addition to the excellent properties of cronidur steel, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment, and its application range is expected to be further expanded.Equipment maintenance,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.H-section steel

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.Application process,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.Blanking shall be carried out according to the design and site, and then the groove shall be made with a grinder with a groove angle of ° ~ °. Fix the processed pipe on the support, and the gap between the two pipes is mm ~ mm, and then weld.Function of I-beam: where is I-beam mainly used?Port Natales, eliminate structural defects, reduce strength, improve plastic deformation,Port NatalesHigh pressure alloy pipe, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness reduce the product cost and reduce the quenching process
