They do not need to protect them from mechanical damage.

9Longitudinal welded pipe has the advantages of simple production process, high production efficiency, low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight welded pipe. It can produce welded pipe with larger pipe diameter with narrow blank, and welded pipe with different pipe diameter with blank of the same width. However, compared with the straight seam pipe with the same length, the weld length increases by ~ ,Products Show and the production speed is low. Welded pipes with large or thick diameter are generally made of steel blank directly,San Vicente de MoraviaCombien coûte 32b I - bar par mètreGestion professionnelle while small welded pipes and thin-walled welded pipes only need to be welded directly through steel strip. Then after simple polishing, wire drawing is OK. Welded pipe is welded with strip steel so it is not as high as seamless pipe in its original position. Welded pipe process: uncoiling of raw materials - leveling - end shearing and welding - looper - forming - Welding - removal of internal and external weld beads - pre correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - hydraulic inspection - Pickling - Inspection (strict control) - Packaging - delivery.

eAseriI-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.

There is a great demand for welded steel mesh in China&#;s market.

BNkotenGalvanized pipe is actually galvanized pipe. This is mainly because it increases the corrosion resistance of the steel pipe, so it is evenly coated with a layer of zinc. It can prevent the erosion of other chemicals such as and steam, and protect the steel strip. It is non-destructive and effectively prolongs its service life. Generally, the steel strip purchased is rolled into a large number by the galvanized pipe manufacturer, so pay attention to it during storage.

Fa Cleaning: first, dust and other substances attached to the surface of the galvanized pipe after cleaning.

Stretch punching by steel plate equipment; The main purpose is to be used in the structure of scaffold.

Phosphorus: it can significantly reduce the plasticity and toughness of steel,Products Show especially at low temperature. This phenomenon is called cold brittleness. In high-quality steel, sulfur and phosphorus should be strictly controlled. On the other hand, low carbon steel contains high sulfur and phosphorus, which can make it easy to cut, which is beneficial to improve the machinability of steel

lI-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.

TFirst, the wall thickness of high-quality and smooth steel is particularly thick. Because the thicker the wall thickness of the product, the higher the economy and practicability. The thinner the wall thickness, the greater the processing cost and opportunity,Products Show and the higher the resource cost. Secondly, the process of smooth steel also determines its limitations. Generally smooth steel has low precision,San Vicente de MoraviaCombien coûte 32b I - bar par mètreGestion professionnelle uneven wall thickness, low brightness inside and outside the pipe, high length cost, pockmarks in the internal appearance, and black spots are not easy to remove. Again, the inspection and shaping need to be processed offline. Therefore, it has its advantages in high pressure, high strength and mechanical structure materials. In the process of use,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd we will gradually find out. In fact, seamless pipe has also entered the market in recent years. With the growth of market demand, 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, resulting in stress, namely thermal stress. Under the action of thermal stress, the starting temperature of the surface layer is lower than that of the core layer, and the shrinkage is greater than that of the core layer, making the core layer stretch. At the end of cooling, 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, under the action of thermal stress, the surface of the workpiece is compressed and the core is pulled.

aKGalvanized pipe refers to the shape and high frequency of hollow square steel pipe welded by the back of the steel pipe during the hot rolling or cold rolling of galvanized steel plate or cold bending of galvanized steel plate, or before the galvanization of cold hollow pipe. Galvanized. Galvanized square pipe can be divided into hot galvanized pipe and cold galvanized pipe from the production process. This is because the two galvanized pipes are different, which also leads to many different physical and chemical properties.

Chromium can improve the hardenability and wear resistance of steel, and improve the corrosion resistance and oxidation resistance of steel

Acceptance according to standards

packingz Whether the mesh size and wire diameter of electric welding mesh meet the standards

VI-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.

It has a thick and dense pure zinc layer covered on the steel surface, which can prevent the steel substrate from touching with any corrosion solution and maintain the steel substrate from corrosion. In general atmosphere, which is difficult to dissolve in water, so it plays a certain maintenance effect on steel matrix. If zinc oxide and other components in the atmosphere form insoluble zinc salts, the anti-corrosion effect is more ideal.

vAseriWhat is theof defect detection of seamless pipe? Magnetic particle testing or penetrant testing of seamless pipes can effectively find surface defects such as cracks, folds double skin, hair lines, pinholes and so on. Because of its high detection sensitivity, magnetic particle detection method should be preferred for ferromagnetic materials. For non ferromagnetic materials, such as stainless steel seamless pipe, penetrant testing method is adopted.

fNFirst, the wall thickness of high-quality and smooth steel is particularly thick. Because the thicker the wall thickness of the product the higher the economy and practicability. The thinner the wall thickness, the greater the processing cost and opportunity, and the higher the resource cost. Secondly, smooth steel has low precision, uneven wall thickness, low brightness inside and outside the pipe, high length cost, pockmarks in the internal appearance, and black spots are not easy to remove. Again, the inspection and shaping need to be processed offline. Therefore, it has its advantages in high pressure, high strength and mechanical structure materials. In the process of use, we will gradually find out. In fact, seamless pipe has also entered the market in recent years. With the growth of market demand, the advantages of seamless pipe have also been stimulated. But there are also many fakes and fake products on the market. Be careful when you choose.

Seamless tube has high elasticity, no memory, no deformation, anti-static.
