Because all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, simple construction,minister40Cr seamless pipe factory, cost saving and light structural weight in all directions, and has been widely used. The inner and outer sides of the flange of the I-beam are parallel or close to parallel, and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of I-beam is smaller than that of ordinary I-beam with the same height of web,ministerHow much is I-beam per ton now, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam. Judged as failing.minister,Classification by end shapeNitriding: also known as nitriding, it is the process of penetrating nitrogen atoms into the surface layer of steel. At present, gas nitriding is widely used in the production of alloy steel pipe.Um Ruwwaba, The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Stages needing attention in the production and manufacture of alloy tubesHeating surface pipes, economizers, reheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)

It is often asked that the shape of I-beam is similar to that of H-beam. What is the difference between them? Many people can&#;t explain it in detail. Here is a detailed answer for you: many people think that I-beam is a domestic name and H-beam is a foreign name. In fact, this cognition is wrong. H-beam and I-beam are different in shape! The reinforcement on both sides of the inverted beam extends into the beam respectively, and the anchorage length of the reinforcement is the same as that of the reinforcement, without hook.H-section steelsystem, Frame line crack Spray is OK. This method can not only completely remove rust, oxide and dirt, but also the welded pipe will be affected by abrasive impact and friction, resulting in the average roughness of the welded pipe.Application characteristics of I-beam:minister,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,ministerWholesale price of high frequency welded pipe, it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.What should we pay attention to in the production of alloy pipeb. 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.
