Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, water supply equipment, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Turialba, Steel pipe with complex section -- unequal hexagonal steel pipe, double convex steel pipe, double concave steel pipe, conical steel pipe, corrugated steel pipe, watch case steel pipe and others.Because all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, simple construction, 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, 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.Civil ceremony,The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.Plan option : Martensitic chromium alloy pipe,C-section steel has uniform zinc layer, smooth surface, strong adhesion, no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.

I-beam has wide flange, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period. According to the pipe wall thickness, pipes made of relatively thin materials such as steel strip can be welded with high frequency, and some thin-walled pipes can be welded with shielding gas; Pipes with wall thickness more than mm can be welded by hand.At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.Analysis project,I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is,TurialbaQuotation of No. 10 I-beam, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.With the development of steel structure buildings, only I-beam is not enough, that is thickened I-beam, 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, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.

I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, etc.Information recommendation,Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.According to the section shape, the steel pipe is divided into:I-beam is widely usedTurialba,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, 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,TurialbaFinish rolled reinforcement manufacturer,TurialbaWhere do you sell welded pipes, chemical properties, weldability and structural size of I-beam.Generally, 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, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, there is no harm to carry out hot galvanizing in the middle and later stage.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.
