How to distinguish the quality of galvanized pipes
Distinguishing the quality of galvanized pipes: 1. Generally, defective galvanized pipes are in a folded state, and the appearance of such folded galvanized pipes is the main reason for this kind of folding line. This disadvantage often runs through the longitudinal direction of the entire product, and the reason for folding may be due to some manufacturers who cannot meet the requirements excessively pursuing high efficiency, When the amount of compression is too large, this folding will occur, and if this folded galvanized pipe is used for bending, cracking may occur, and the strength of such steel is not high. 2. And some defective galvanized pipes may also have pits on the surface, which may be caused by the irregular and uneven surface of the production equipment used by the manufacturer of galvanized pipes. This is because defective galvanized pipes often cause the production equipment to overspend, resulting in the appearance of pits. 3. However, galvanized pipes with poor quality are often prone to scabbing, as the raw materials produced by generally low-quality galvanized pipes are mostly not very uniform and contain relatively high amounts of impurities. Moreover, the production equipment of low-quality galvanized pipe manufacturers is mostly very rudimentary, which can easily cause problems such as sticking steel, which can cause scars on the produced galvanized pipes.
