Now galvanized pipe has been widely used in all walks of life. Long ago, galvanized pipe was also used for home pipe installation. Street lamp is a common lighting tool on the road, and it is also a necessary thing for urban lighting. It is said that where there is a road, there is a lamp.
As a part of pole purchase, its price is also a part of considering manufacturer cooperation as a middleman. At present, Jinan galvanized pipe street lamp is commonly used in the market, because its corrosion resistance is good, and it can prevent rusting for more than 10 years.
First, galvanized pipe
We have galvanized or hot-dip steel pipes called galvanized pipes, which are generally cheap wholesale prices.
2、 Disadvantages of using galvanized pipe如果采用镀锌管焊接，由于其表面附着有防腐材料，其表面会有大量的焊渣或焊料难以处理。但热浸镀锌灯杆的制作工艺一般是先用黑管(即铁管)焊好，然后再经过酸洗除去铁锈和热浸镀锌，这样锌层就会覆盖一些焊点。另一方面是防腐方面，因为焊丝高温会破坏其表面的防腐层，如果不进行处理，很容易生锈。为什么院子灯用的镀锌管这么好?由于其高度只有3-5米，法兰部分的上部只需要点焊，而且它不会增加钢筋，所以表面焊渣少。
If galvanized pipe is used for welding, due to the anti-corrosion material attached to its surface, there will be a lot of welding slag or solder difficult to handle. However, the manufacturing process of hot-dip galvanized lamp pole is generally to weld with black tube (i.e. iron tube), then remove rust and hot-dip galvanizing through pickling, so that the zinc layer will cover some welding spots. On the other hand, it is anti-corrosion, because the high temperature of welding wire will damage the anti-corrosion coating on its surface, if not treated, it is easy to rust. Why is the galvanized pipe used for yard lamp so good? Because its height is only 3-5M, the upper part of the flange only needs spot welding, and it will not increase the reinforcement, so the surface welding slag is less.
In fact, the advantages and disadvantages of using Jinan galvanized pipe pole actually co-exist, but we suggest that you choose hot-dip galvanizing or environmental protection materials when purchasing street lamps. The street lamp installed in this way is not only beautiful, but also practical, especially the anti-corrosion effect is very good.
