During the heating and cooling process of structural welded pipe workpiece, due to the inconsistent cooling speed and time of surface layer and core layer, the temperature difference will be formed, resulting in uneven volume expansion and contraction, namely thermal stress. Under the action of thermal stress, the starting temperature of the surface layer is lower than that of the core layer,Products Show and the shrinkage is greater than that of the core layer making the core layer stretch. At the end of cooling,Los Angeles09CrCuSb alloy pipeHow maintenance can extend the service life the surface layer is compressed and the core is stretched because the cooling volume contraction of the core cannot be carried out freely. That is, the surface of the workpiece is compressed and the core is pulled.

1Galvanized pipe has excellent corrosion resistance. Compared with traditional steel, its application life is longer. Secondly, this kind of pipe has strong resistance to baking. In case of critical situation, it will not lead to the collapse of building structure in a short time. In addition, that is, it is more convenient and lighter when carrying out the construction and installation. The operators save time and labor when carrying out the construction, it is not difficult to understand why the galvanized pipe is so favored by various construction units.

sHoustonAlloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production,Products Show manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.

Operating conditions

JSasariThe product can withstand any range of operating temperature.

BxThe reinforcement mesh is used for embankment protection or for the protection of the whole riverbed and river bank, which is more suitable for the river channel with relatively gentle original bank slope. Taking the design dry water level as the boundary, the upper part is slope protection works and the lower part is foot protection works.

Due to the impact of poor visual . Only through the application of mesh and the overall stiffness can we see the potential of demand. The application of steel data is a high one, such as the reuse rate of mesh and reinforcement installed in the current mesh production company and the treatment of corrosion. The design strength value of circular reinforcement and the design strength value of welded reinforcement mesh. According to the equal strength substitution principle and considering comprehensive factors, the use of steel welded mesh plate can save the use of steel bars in the steel welded mesh plate factory. And the reinforcement mesh needs to be processed after it is shipped to the site, so there is no wear.

Because zinc has excellent ductility and its alloy layer is firmly attached to the steel base, hot-plated parts can be formed by cold stamping, rolling,Products Show wire drawing, bending and so on without damaging the coating;

mStages needing attention in the production and manufacture of alloy tubes

EHot rolled smooth round steel is structural steel,Los Angeles09CrCuSb alloy pipeHow maintenance can extend the service life with chemical composition content of C carbon .%, Si silicon .%, Mn manganese %, s sulfur ≤ .%, P phosphorus ≤ .%, yield strength of mpa and tensile strength of MPa. High temperature continuous casting and rolling or ingot heating rolling. Soft, good weldability, high ductility,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd.

WTest resultsFirst, we can clean the outer surface of the welded pipe with solvent or emulsion. This method is very effective for cleaning the oil stain, dust and other organic matters on the surface of the welded pipe.

jPGalvanized pipe, also known as galvanized 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, and the corrosion resistance is worse than that of hot dip galvanized pipe.

Welded thin-walled pipe: mainly used for making furniture, toys, lamps, etc. In recent years, thin-walled tubes made of stainless steel strip are widely used, such as high furniture decoration, fence and so on.

The surface of hot-dip galvanized parts is bright and beautiful.

Recommendation and consultationuMetric 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.

QAs shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, which makes the outer flange thin and the inner flange thick. Therefore, the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance.

High percentage of metal strength.

uHoustonA major defect is its instability to the corrosion process which can not resist all factors. Producers need a solution that can solve the corrosion problem. The decision has been found. They become a galvanized steel pipe.

eHGalvanized pipe: the zinc layer of cold galvanized pipe is an electroplating layer, and the zinc layer is separated from the steel pipe substrate. The zinc layer is very thin. The zinc layer is simply attached to the steel pipe substrate and is easy to fall off. Therefore, its corrosion resistance is poor. In new homes, it is forbidden to use cold galvanized pipes as water supply pipes.

Divided by weld -- straight welded pipe and spiral welded pipe.
