Calculation method of wall thickness and weight of high mast light poles

The calculation method of the wall thickness and weight of high mast light poles involves multiple engineering parameters and environmental factors. Through reasonable calculation process and case analysis, the safety and economy of the design can be ensured.

The weight of the high mast light poles is determined by the wall thickness and diameter. Many customers are accustomed to asking about the wall thickness when ordering high mast light poles because customers know that the thickness of the tube wall determines the life span and corrosion resistance of the high mast light poles, so this is particularly important.

Many high mast light pole manufacturers do not care about the questions raised by customers, because they can say as thick as possible, for example, they report 8mm for 6mm thickness, 10mm for 8mm thickness, etc. In a word, "it is better to sell than to buy". Aren't manufacturers afraid of being discovered by customers by doing this? You don't have to say it, they are not afraid, why do you say that, because they have ways to cover up the "truth".

First of all, the bottom flange of the lower section of the high mast light poles cannot be measured, because the flange is welded to the cross-section of the tube body, and no one can measure it once it is welded. Another is the hook ring at the top, which cannot be measured either, because there is a triangular lightning rod fixing plate at the top that is fully welded on the upper diameter, so there is no way to measure it.

Seeing this, some friends will say, then the middle plug section can be measured, right? Yes, it can be measured here, but the manufacturer still has a way to deceive. First of all, the anti-corrosion process of the high mast light poles is hot-dip galvanizing plus spraying. The thickness of hot-dip galvanizing is 85 μm, and the thickness of spraying is 0.3mm. The thickness of these two processes added together is close to 0.5 mm. *Finally, there is an even more unique trick - the percussion thickening method. This word is new, maybe many friends don’t understand it, but you will understand it after listening to me. The so-called percussion thickening method refers to the use of a hammer to knock around the diameter of the pole body. The wall thickness of the steel pipe will expand to one side after being stressed. The result is self-evident, right? It is so simple to increase the wall thickness by 1-2mm.

There is a way to identify whether there is water in the wall thickness of the high mast light poles. We can measure the accuracy of the wall thickness of the pole by calculating the weight. For example, a relatively simple calculation formula (upper mouth + lower mouth; height; 2s; 3.14s; wall thickness; density = weight) is used to make a simple calculation, and then it is passed on the scale. If the weight does not match, it must be fake.

Another method is relatively simple, that is, touch, touch 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 smooth it, and then measure it with a caliper. This measurement result is the most accurate actual wall thickness.
