Classification by wall thickness

6Galvanized pipe, also known as galvanized pipe

Classification by wall thickness

6Galvanized pipe is divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick, the coating is uniform, the adhesion is strong and the service life is long. The electroplating cost is low, the surface is not smooth, the section modulus,Products Show 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,AseriCombien coûte 65 tubes soudés par mètreLes prix du marché peuvent encore baisser pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.

Silicon; it can improve the hardness of steel, but the plasticity and toughness decrease. Electrical steel contains a certain amount of silicon, which can improve the soft magnetic properties

MTalma Quality requirements

NtFirst, the two hole beam end space on the pier top shall be used to set the cast-in-situ transverse cantilever cantilever beam, on which the prefabricated micro bending plate shall be installed. The second is to erect prefabricated sidewalk beams in the cantilever part of the cantilever beam. The sidewalk beams of bridge openings on both sides are longer than the main beam, one end is supported on the cantilever beam of side pier, and the other end is supported on the special buttress on the embankment, which is to avoid widening the abutment.

In order to ensure the welding quality of pipes,Products Show welders shall be trained, tested and qualified. In addition to the basic theory, the welder should consider the operation skills. The pipe welding process may include several postures of overhead welding, vertical welding and overhead welding (when the pipe cannot rotate). The size of current should be selected to take into account the formation of vertical welding and overhead welding (some pipes are not very large, and the current cannot be adjusted in the middle of one formation). In the process, the stability and formation of arc should be controlled, It can swing properly, and the forming shall be well combined with the necessary swing.

Manganese: it can improve the strength of steel weaken and eliminate the adverse effects of sulfur, and improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical properties

rThe specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. The types of I-beam include hot-rolled ordinary I-beam Light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~ mm,Products Show expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system,AseriCombien coûte 65 tubes soudés par mètreLes prix du marché peuvent encore baisser cross rolling pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.

ZHigh percentage of metal strength.

ZInspection itemsGalvanized steel pipe: in order to improve the corrosion resistance of steel pipe, general steel pipe (black pipe) shall be galvanized. Galvanized steel pipes are divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick and the cost of electro galvanizing is low.

pE The zinc layer obtained by electroplating is relatively pure, which corrodes slowly in acid, alkali and other fog, and can effectively maintain the steel matrix;

Carbon: the higher the carbon content, the higher the hardness of steel, but the worse its plasticity and toughness

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,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd 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, with quality assurance certificate and certificate, which meet the process requirements; The recovery of welding rod head shall be strictly controlled to ensure the flow direction and dosage; Welding materials shall be baked in strict accordance with the process, and the amount of one-time distribution shall not exceed half a day.

aEspazaLongitudinal 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, the welding length is increased by ~ , and the production rate is low.

iR Welded steel mesh, a new form of reinforcement, is especially suitable for large-area concrete engineering.

From the current scope of use, it is mainly widely used in glass curtain wall, power tower, communication power grid and other industries. In recent years, it has been widely used in many regions and industries, which is enough to show that the quality of galvanized pipe is very good, and it also brings a lot of convenience in the process of use, so it can be used better.
