RamshaherQ345 thick wall seamless pipe,

The key purpose of grinding and polishing alloy pipe is to moisten the surface, and the relevant limit accuracy or appearance change is not easy to change.Determined by the shape, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in bearing bending moment, it can greatly improve the bearing capacity and save metal by % ~ %.Ramshaher,First, we can clean the outer surface of the welded pipe with solvent or emulsion. This method is very effective for cleaning the oil stain, dust and other organic matters on the surface of the welded pipe.Ways to obtain surface compressive stress characteristics of alloy tubesFrutillar,After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, If the current flows from the positive stage to the negative stage a layer of zinc is deposited in the pipe.With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, which is easy to lose stability for load-bearing columns.Advantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumption

I-beam, whether ordinary or light, so its application range is very limited. I-beams are widely used in buildings and other metal structures.Longitudinal welded pipe has the advantages of simple production and processing technology, high production efficiency, low cost and rapid development trend. The compressive strength of spiral welded pipe is generally higher than that of straight welded pipe. Narrow blank can be used to produce welded pipe with large pipe diameter, and blank with the same total width can also be used to produce welded pipe with different pipe diameter. However, compared with the straight seam pipe with the same length, and the production rate is low.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.Online consultation,Due to the relatively high and narrow section size of ordinary I-beam and light I-beam the moment of inertia of the two main axes of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.With the development of steel structure buildings, only I-beam is not enough, that is thickened I-beam, which is easy to lose stability for load-bearing columns. Miscellaneous scab

The section of I-beam has good straight pressure and tensile resistance, but the section size cannot resist torsion because the wing plate is too narrow. On the contrary, H steel has its own advantages and disadvantages.Variable cost, Remove defective pipes within the allowable length. Material requirementsBecause 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, 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.Ramshaher,Ramshaher13CrMo44 alloy pipe, Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity,Ramshaher42CrMo thick wall alloy pipe, 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.→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.Application characteristics of I-beam
