c. quality inspection is carried out for alloy pipes, so that the whole process of steel pipe processing is under reasonable inspection and supervision, and the product quality is reasonably guaranteed.Key technical characteristics of alloy pipeAntwerp,The multi-al combination of reinforcement mesh welding machine and reinforcement mesh row welding machine based on PLC basic control. At present the full-automatic mesh welding machine has the characteristics of simple operation, high control precision and easy to master the process of high-speed continuous welding. Frame line crackSalem,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, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, etc.What are the requirements for alloy pipe construction accessories

At the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.Galvanized pipe is often seen in our daily life, especially in some construction sites. This product has the advantage of durability when used. It also has the characteristics of surface gloss,AntwerpHow much is 32B I-beam per meter, uniform zinc layer and no missing plating. Moreover, the cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings. In addition, this product also has the characteristics of no dripping, strong adhesion, its service life is also very long, and it also has the characteristics of corrosion resistance. The standard anti rust thickness of hot-dip galvanizing can be maintained for more than years without repair. This is used in some suburban environments. However, in urban or offshore areas, standard urban or offshore areas can be maintained for years without repair. The products produced by our company must meet these requirements. Friends who need to order can call us directly.I-beam is widely usedRange,Antwerp16Mn thick wall seamless pipe,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, boronizing, siliconizing and so on are commonly used in production. Miscellaneous scabMixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.

What are the requirements for alloy pipe construction accessoriesExecutive standard,Plan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min. After chromate passivation, the zinc coating forms white, colorful and military green, which is beautiful and generous and has certain decoration;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,AntwerpIs the steel bar cold rolled or hot rolled, Shangang huangte, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, etc.Antwerp,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, Baotou Iron and steel, Shangang, huangte, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, without high carbon steel and high chromium alloy pipe. The aqueous solution contains % sodium cyanide % ~ % (volume ratio), the solution temperature is ~ ℃, and the solution time is min.
