Acceptance standards for hot-dip galvanized square pipes
Hot dip galvanized square pipes are generally judged based on the appearance of the product to determine whether they are qualified. If there are missed plating, pitting, white spots, double skin, bubbles, green discoloration on the surface of the outer wall of the square pipe, and the frequency of occurrence is too high, it is determined as an unqualified product. But in product standards, there is a specified range of deviations for products, which is the "allowable deviation" of dimensions. If you have any questions, please contact the customer manager of Yuantai.
Theoretical weight calculation formula for hot-dip galvanized square pipes
Calculation formula for ordinary square tubes per meter: (length+width) * 2 * wall thickness * 0.00785=weight per meter, while calculation formula for hot-dip galvanized square tubes: (length+width) * 2 * thickness * 0.00785 * 1.06=weight per meter
