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， 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， breaking the clean Legion and strong corrosion resistance. Even if it is used in some places where the environment is not good， 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，Products Show 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.
FCranbourne Galvanized 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.
My 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;
From the situation of chiseling on site， the reinforcement mesh laid by the construction party is cm below the surface layer， which greatly exceeds the specification， and then the crack resistance of the reinforcement mesh can be reduced. Because of the increasing temperature， the effect of thermal expansion and cold shrinkage and the characteristics of concrete， the cracking of surface layer is significant.
Galvanized pipe is a kind of light thin-walled steel pipe with hollow square section，Products Show also known as steel cold-formed profile. It is a section steel with square section shape and size， which is made of Q hot-rolled or cold-rolled strip or coil as the base material，Wanjin City45 tubes en acier sans soudure à paroi épaisse de grand diamètreÉléments d'attention à la coordination de l'installation cold bending and high-frequency welding. In addition to wall thickness thickening， the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe. Good comprehensive mechanical properties， weldability， cold and hot workability and corrosion resistance， and good low temperature toughness.
gHowever， what we need to do now is to improve the production technology level of China&#;s production process of C-section steel， and step up the formulation of relevant industry standards and inspection standards. C-section steel manufacturers should keep close contact with truck manufacturers and communicate more. In this way， while small welded pipes and thick wall welded pipes must only be welded immediately according to nylon tape. After simple grinding and polishing，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd metal wire drawing is OK.
DdiscountThe 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 marine exploration， metal structure， power transportation， shipbuilding， etc.)， agriculture (such as sprinkler irrigation， heating room) construction (such as water and gas transportation， wire casing， scaffold， house， etc.)， bridges， transportation， etc. because hot-dip galvanized products
qFThe pollution of the joint causes the welding cracking. The composite pipe welding is an accurate work. If it is not done well， it will not only waste resources， but also lead to work efficiency， rework and restart， and waste financial resources.
The reinforcement mesh of the maintenance platform has the characteristics of extensive application， convenient installation and durability， installation of connectors and other accessories can be added around. The reinforcement mesh is suitable for the reinforcement mesh manufactured in the factory and welded with cold-rolled ribbed reinforcement or cold-rolled smooth round reinforcement. The welded reinforcement mesh for reinforced concrete is a good and efficient material for concrete distribution. Flat steel with different specifications can be used for edge wrapping Or wrap edges with angle steel， channel steel， square tube， etc; Handles and hinges can also be installed on the reinforcement mesh that needs to be moved or opened frequently.
During the construction of building wall， cracks and hollows show that the construction materials are unqualified， the construction at the matrix junction is not in place， and the construction personnel are poor. The external wall plastering adopts electric welding steel wire mesh， including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology， the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small)， a group of vertical rolls must be added for rolling at the same time. Therefore， its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm， which exceeds the welded composite section.
The smooth of steel pipe is mainly through tension reducing， which is a continuous rolling process of hollow base metal without center and tip. Under the condition of ensuring the capillary welding quality， the whole welded pipe is heated to more than ℃ by the welded pipe tension reduction process， and then rolled to finished pipes with various outer diameters and wall thicknesses by the tension reduction machine ( times in total). The fluid pipes produced by developed countries in the world have adopted the welded pipe smooth process in a large number of boiler pipes. With the development of society， Domestic hot welded pipe has gradually formed a situation to replace smooth pipe.

aTA 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.
Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility， so it is flexible. Galvanized pipe is widely used in architecture. This product must have been seen by everyone. However， there are many types of it. When you buy it， you should also find out which one you need. The reason why it is favored by everyone in the market is inseparable from its advantages. Next， Xiaobian will lead you to see the advantages of galvanized pipe.
