The zinc plating tubes are generally used for building houses, mechanical manufacturing, electrical engineering, plasticity, flexibility and intensity. So, what's the zinc-plated pipe weight formula? Let's find out。
I. Zinc plating pipe weight formula
Weight formula for zinc plating tubes: kg/mw={2(a+b)-4xs}xs×0. 00785
Formula, a, b is rectangular length (mm), s is wall thickness (mm)
Example: 30 mm x 20 mm rectangular tube, 1 mm wall thickness for mass per metre
= (2 x 50-4) x 1 x 0. 00785 kg = 0. 7536 kg
Ii. Characteristics of zinc plating tubes
1. A thick, dense, pure zinc layer is over the steel surface, which avoids contact with any corrosive solution and protects the steel matrix from corrosion. In the general atmosphere, the zinc layer surface forms a thin and dense layer of zinc oxide, which is difficult to soluble in water and thus has a protective effect on the steel matrix. If zinc oxide and other constituents in the atmosphere produce insoluble zinc salt, the protection against erosion is desirable。
An iron- and zinc alloy layer, which combines to be dense and displays specific corrosive properties in the oceanic salt fog atmosphere and the industrial atmosphere
3. The combination is strong and zinc-iron is soluble that it is very resistant
4. The alloying layer and the steel base are solid because of the good extension of zinc, so that thermal plating is capable of cooling, rolling, radging, bending and so on without damaging the plating
5. When the steel structure is hot-filled with zinc, it is equivalent to a discharge treatment that effectively improves the mechanical performance of the steel matrix, removes the stress of steel formation welding and facilitates carwing processing of steel structures。
6. The surface is bright and beautiful after thermal zinc plating。
7. Pure zinc is the most plastic layer of zinc plating in the thermal plating, which is more or less similar in nature to pure zinc and is dilatory in nature, and is therefore more intrusive。
