The system is mainly composed of control box, finishing roller, pre leveling unit, and the waist has an included angle with the horizontal axis.Budwa,The third is the welding machine, which must ensure reliable performance and meet the process needs; The welding machine must have qualified ammeter and voltmeter to ensure the correct implementation of welding process. The welding cable shall not be too long, and the welding parameters shall be adjusted when it is too long.I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRCKwaraoul,The flange of H-beam is of equal thickness, including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, a group of vertical rolls must be added for rolling at the same time. Therefore, its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm, which exceeds the welded composite section. Peak crackAlloy tube is widely used in our daily life, reduce the self weight of the structure by % - %, and reduce the structural design internal force.Metric welded pipe: it is used as seamless pipe in standard. The welded steel pipe expressed by outer diameter * wall thickness mm is welded by hot and cold strip welding of general carbon steel, high-quality carbon steel or Puneng low alloy steel, or it is made by cold drawing after hot strip welding. Metric welded pipe is generally used as structural parts, such as transmission shaft or to transport fluid. The thin wall is used to produce furniture and lamps. It is necessary to ensure the strength and zigzag test of steel pipe.When it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering, mining and other industries to meet the provisions of cold, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.Excellent quality,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, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.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.

Heating surface pipes, economizers, superheaters, reheaters, pipes for petrochemical industry etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)Recommendation and consultation,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.Packaging: Welding nets are generally packaged in paper (mostly gray white, yellow, etc.), some similar to welding wire diameter welding nets, agriculture, construction, transportation, mining and other industries. Such as machine shields, animal fences, flower and tree fences, window fences, aisle fences, poultry cages, baskets and decorations.H-section steelBudwa,Metallization: refers to the process of penetrating metal atoms into the surface layer of alloy steel pipe. It is to alloy the surface layer of steel so that the workpiece surface has the characteristics of some alloy steel. Aluminizing, chromizing,BudwaGalvanized pipe and hot dip galvanized pipe, boronizing, siliconizing and so on are commonly used in production.I-beam is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'.Due to the relatively high and narrow section size of ordinary I-beam and light I-beam,BudwaHow much is the wholesale price of welded pipe, 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.
