Calculation method of wall thickness and weight of high pole lamp
The weight of the high pole lamp is determined by the wall thickness and diameter. Many customers will habitually ask about the wall thickness when customizing the high pole lamp, because the customer understands that the thickness of the tube wall determines the life of the high pole lamp Length and corrosion resistance years, so this is particularly important.
Many high-pole lamp manufacturers don’t care about the questions raised by customers, because they can say as thick as possible. For example, if they are 6mm thick, they will say 8mm, 8mm thick they will say 10mm, etc., in short, “Buy It’s not as good as selling it.' Isn't the manufacturer afraid of being discovered by the customer? Don't you say that they are really not afraid, why do you say that, because they have a way to cover up the 'truth.'
First of all, the bottom flange of the bottom section of the high pole lamp cannot be measured, because the flange is welded to the cross section of the tube body, and no one can measure it as long as it is welded. There is also the hook ring at the top, this part cannot be measured, because there is a triangular lightning rod fixing plate on the top which is fully welded on the upper diameter, so there is no way to measure it.
When you see this, some friends will say, then the middle plug-in section can always be measured, right? Yes, it can be measured here, but the manufacturer still has a way to deceive it. First of all, the anti-corrosion process of the high pole lamp is hot-dip galvanizing and spraying. The thickness of hot-dip galvanizing is 85μm and the thickness of spraying is 0.3mm. The thickness of the craft is close to 0.5 mm when added together. Finally, there is an even more amazing method-percussion thickening method, this term is new, maybe many friends do not understand, but you all understand when I say it, the so-called percussion thickening method refers to the use of a hammer When the rod is knocked around the diameter of the rod, the wall thickness of the steel pipe will expand to one side after the force is applied. The result is self-explanatory, right? It's that simple to increase the wall thickness by 1-2mm.
It is not impossible to identify whether there is moisture in the wall thickness of the high pole lamp. We can measure the accuracy of the pole wall thickness by calculating the weight, such as a relatively simple calculation formula (upper mouth + lower mouth × height ÷ 2 ×3.14×wall thickness×densityu003dweight) to do a simple calculation, and then pass the weighbridge. If the weight is not correct, it must be a fraud.
There is another simpler method, which is to touch, touch the circumference of the inner diameter with your fingers. If the diameter is knocked, it will definitely not be flat. At this time, you only need to use a steel file to grind it, and then use it. Caliper measurement, this measurement result is the most accurate actual wall thickness.
