After hot-dip galvanizing of steel structure， it is equivalent to one-time annealing treatment， which can effectively improve the mechanicalof steel matrix， eliminate the stress during steel forming and welding， the full-automatic mesh welding machine has the characteristics of simple operation， high control precision and easy to master the process of high-speed continuous welding.

The correct and reasonable use of galvanized pipe can play a better role. The product can be widely used in the market because of its obvious performance advantages. Both strength and toughness are worth our choice. Lets see what the specific uses are and what the acceptance standards are?
KBetel nut in DanThey do not need to protect them from mechanical damage.
DbIt bears high internal working pressure.
Effect of trace elements on properties of galvanized pipe
The end span plate is connected with the load-bearing wall. The length of the surface mesh extending into the grid support shall not be less than mm，Products Show and a transverse reinforcement shall be provided at the end of the mesh or the extended reinforcement shall be bent.
vThe general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe，Memphis12Cr1MoVG alloy pipe factoryPrecautions for the use of tools not very little aluminum alloy， and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.
SClassification by production method
SOnline consultationAccording to the data information display information， there is an inseparable correlation between the annual real estate sales data information and the apparent consumption data information of galvanized pipe. From the consumption surface of the middle and lower reaches of galvanized pipe， decoration design， elevator car， handicrafts household appliances and other industries are closely related to the situation of the real estate industry.
dMSpecial shaped pipe: square pipe， rectangular pipe， cap pipe， mainly used as agricultural machinery components，Products Show steel windows and doors， etc.
The production methods of seamless pipe are roughly divided into cross rolling method and extrusion method. The cross rolling method is to drill the tube with a cross roll， and then extend it to the rolling mill. This method has fast production speed， but has high requirements for the workability of the blank. It is mainly suitable for the production of carbon steel and low alloy steel pipes. The extrusion law is to pierce the blank or ingot with a punch， and then squeeze it with a steel pipe with an extruder. The efficiency of this method is lower than that of cross rolling method. It is suitable for producing high-strength alloy steel pipe. The billet or ingot must be heated before cross rolling method and extrusion method. The produced steel pipe is called thermal correlation. Steel pipes produced by hot working can sometimes be cold worked as needed. There are two methods of cold working. One is cold drawing. In other words， pull the pipe to the pipe and tilt it to make the steel pipe gradually thinner and longer. Another method is cold rolling. The method of applying the hot smoke invented by brother to cold processing. The cold working of seamless pipe can improve the dimensional accuracy and finishing of steel pipe， and improve the mechanical properties of materials.
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， wire drawing，Products Show bending and so on without damaging the coating;
Quality recommendationvIn order to ensure the welding quality of welded pipe， the forming roll，Memphis12Cr1MoVG alloy pipe factoryPrecautions for the use of tools guide roll， extrusion forming roll and sizing roll must be adjusted once， and then the most important thing is to adjust the closing plate hole， guide roll and extrusion forming roll of the forming roll. Among them， the guide roller has the s of controlling the weld direction of the welded pipe and the height width ratio of the finished rolled pipe， reducing the edge widening， controlling the edge springback of the finished rolled pipe， and ensuring that the weld is vertical without screwing into the extrusion roll.
CIts heat sealing effect is remarkable. It can be directly buried immediately，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd which can not only save resources， not occupy the natural environment， but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation， prevent actual operation and maintenance meet the requirements of thermal insulation and cold protection， reduce heating equipment unique and convenient installation， and reduce the construction cycle time of the project. On the whole， it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.
Application of galvanized pipe
aNew South MemphisEmulsified asphalt emulsion is also easy to use on the mobile slurry seal paver. It is necessary to mix on the machine and use additives for chemical control for maintenance.
rYIt is divided into circular welded pipe and special-shaped (square， flat， etc.) welded pipe.
The storage of galvanized pipes should pay attention to several points. The first is the storage location. It cannot be placed in the open air， because in the open air， not only the safety of various products such as theft， but also corrosion problems will occur. Open air sites are vulnerable to various extreme weather conditions. Large amounts of rain or snow will erode the zinc coating on the surface to the greatest extent， which may lead to rust of the product. The second is the details of storage. It is not directly exposed to the sun. It shall be cooled and dried and shall not be stored with corrosive articles.
