Pickling: if the material cannot be removed after cleaning， pickling will be selected. Pickling of galvanized pipe is divided into chemical and electrolytic. How to prevent white rust of galvanized seamless steel pipe? It has a certain anti-corrosion effect on the pipeline.
7 Multi channel cold rolling (cold rolling) process. Cold rolling of steel pipe is carried out on multi roll mill. Stainless steel pipes are rolled with round holes composed of variable cross-section circular grooves and fixed taper.
yGuazarI-beam is mainly used in building structure curtain wall engineering， mechanical equipment and vehicle manufacturing.
Filling: welded pipe is welded by electric welding of hot-rolled strip steel so its influence was not as high as that of seamless steel pipe.
TTursenzoda Spiral seam high-frequency welded steel pipe (sy- for general low-pressure fluid transportation takes hot-rolled steel strip coil as pipe blank and is often spiral formed at warm temperature. High frequency lap welding method is selected for welding spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation.
EuGalvanized pipe is a layer of galvanized ordinary steel. This is a layer and is a great anti-corrosion protection.
According to the pipe wall thickness， pipes made of relatively thin materials such as steel strip can be welded with high frequency， and some thin-walled pipes can be welded with shielding gas; Pipes with wall thickness more than mm can be welded by hand.
Welded steel mesh， a new form of reinforcement，Products Show is especially suitable for large-area concrete engineering.
eAlloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length，KanasAlloy pipeIndustry characteristics a large amount of liquid can be transported with an annular tube. In addition， when the circular cross section bears the internal or external axial working pressure， the bearing force is more symmetrical. Therefore， most seamless steel pipes are round steel pipes.
SLongitudinal 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 ~ ， and the production speed is low. Welded pipes with large or thick diameter are generally made of steel blank directly，Products Show 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.
UEconomic managementHowever， these pipes， like other metals， beautiful style， convenient installation and durability， Skirting plate (edge guard plate)， checkered plate guard plate， 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，Products Show Or wrap edges with angle steel， square tube，KanasAlloy pipeIndustry characteristics etc; Handles and hinges can also be installed on the reinforcement mesh that needs to be moved or opened frequently.
Generally， what are the customers requirements and standards during acceptance? When the galvanized pipe is accepted， you can judge whether it is qualified from the appearance， or whether there are problems such as missing plating or bubbles on the outer wall of the whole square pipe. Only by solving these problems in time can it be judged as qualified and better used.
In our daily life and work， we can often see a lot of steel products. At the same time， among many steel products， the figure of galvanized pipe is particularly prominent. This is because this kind of pipe will be applied to many engineering construction we often see in our life. There are also countless products processed with this kind of pipe. For example， in the field of mechanical equipment processing we often see，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd the application of galvanized pipe is more frequent. Lets discuss the application scope of this kind of pipe today.
safety requirements lThe 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.
ZC - section steel is reliable and stable in stress， can be accurately positioned， and is resistant to impact and vibration Moreover， it has good versatility and combination， high production efficiency， low cost and rapid development trend. The compressive strength of spiral welded pipe is generally higher than that of straight welded pipe. Narrow blank can be used to produce welded pipe with large pipe diameter， and blank with the same total width can also be used to produce welded pipe with different pipe diameter. However， compared with the straight seam pipe with the same length， the welding length is increased by ~ ， and the production rate is low.

Galvanized pipe is a name for square pipe， that is， steel pipe with equal side length. It is made of rolled strip steel after process treatment. Steel pipe has been an essential material in building decoration. Galvanized pipe is also used more in decoration， but hot-dip galvanized steel pipe manufacturers need to know about the size of galvanized pipe and several common sizes of galvanized pipe， which is helpful for your purchase!
