The surface of cold galvanized layer is smooth, dense and uniform. It has good mechanical properties and corrosion resistance. The consumption of hot-dip galvanized coating is between % - %. The galvanizing process is complex, surface coating and double-sided coating is different, so the thin-walled pipe shall be galvanized. The zinc coating has strong protection and corrosion resistance.

7The use of hot dip galvanizing has expanded with the development of industry and agriculture. Therefore, hot-dip galvanized products have been widely used in industry (such as chemical equipment, petroleum processing,Products Show marine exploration,Siroli1cr5mo tubes en alliage haute pressionStandard de vie metal structure, power transportation, shipbuilding, etc.), agriculture (such as sprinkler irrigation, construction (such as water and gas transportation, wire casing, scaffold, house,Products Show etc.), transportation, etc. because hot-dip galvanized products

DvFirst, 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, the process of smooth steel also determines its limitations. Generally, smooth steel has low precision, uneven wall thickness low brightness inside and outside the pipe, high length cost,Products Show pockmarks in the internal appearance, and black spots are not easy to remove. Again,Siroli1cr5mo tubes en alliage haute pressionStandard de vie 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.

Oxygen blowing welded pipe: it is used as steel blowing pipe. Generally, small-diameter welded steel pipe is used. There are eight standards from / inch to inch. Made of , ,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd , or q-q steel strip. In order to prevent corrosion, some are aluminized.

The use of welded steel mesh in China is still in its infancy. At present, the use of welded steel mesh in China accounts for less than one of the total amount of steel reinforcement. In the early s, steel welded mesh was listed as a key implementation project by the science and Technology Commission and the Ministry of construction, and specifications and procedures were formulated.

d Hot hole breaking cold rolling method. This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill, cold rolling by few station mandrel mill, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way, the advantages of high efficiency, low metal material consumption, small types, multi specifications and high precision. Therefore it is widely used

R The zinc coating is thick, the crystallization is detailed, and the corrosion resistance is excellent;

LTest conclusionThere are many types of galvanized pipes, mainly including cold plated seamless pipes and hot-plated seamless pipes. But now the previous one is no longer used. The hot-dip seamless tube is still in use. Hot dip galvanized pipe is mainly used for steel pipes with low pressure fluid such as water and gas. When in use, if in normal working environment, the thickness of galvanized layer of hot-dip galvanized seamless steel pipe is up to μ M above, and it has been used safely for about years. It can be seen that its service life is very long. Of course, when purchasing, we should also find regular manufacturers to order. Only in this way can we achieve this service life. As long as the galvanized pipe is cleaned after pickling, it is basically cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank. In order to ensure the quality, electro galvanizing will not be used. There are also some small enterprises in the market. They will use electro galvanizing in production. In this way, although it is much cheaper in price. However, the quality is very good when used, and it is also easy to have problems.

dUDue 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.

The development of steel bar mesh is in line with the development of energy-saving economy

For the surface mesh of the height difference plate, when the height difference is ≤ mm, the surface mesh can be bent and installed; when the height difference plate is more than mm, the surface mesh should be disconnected at the place with height difference and put into the beam respectively. The anchorage length of the reinforcement is required for the reinforcement to extend into the beam.

wherecGalvanized 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.

GThe finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃

The fourth is the welding process method to ensure the strict implementation of the special operation method of galvanized pipe. The welding process includes pre welding groove inspection, control of welding process parameters and operation methods, post welding appearance quality inspection and post welding nondestructive testing if necessary. Control the welding level and the amount of welding materials at each crossing.

Galvanized pipe is a layer of galvanized ordinary steel. This is a layer and is a great anti-corrosion protection.
