Products Advantages

The advantages of galvanized pipes mainly include strong corrosion resistance, simple connection, and economic practicality, while the disadvantages include relatively poor durability, restricted usage conditions, and insufficient environmental friendliness. Galvanized pipes have high corrosion resistance because they are covered with a layer of zinc on the surface, which can effectively prevent the steel pipe from being corroded. Especially in humid or corrosive environments, galvanized pipes show a longer service life. In addition, due to the protective effect of the zinc layer on the steel pipe, galvanized pipes also have good anti-rust performance, can keep the surface smooth and clean, and are not easy to rust.

Q1: What's the lifespan of galvanized pipes?
A: 20-50 years depending on environment (HDG lasts 2-3x longer than EG).
Q2: Can galvanized pipes be welded?
A: Yes, but requires zinc removal at weld joints to prevent toxic fumes.
Q3: How to calculate pipe weight?
A: Formula:
Weight (kg/m) = (OD - Wall Thickness) × Wall Thickness × 0.02466
Q4: MOQ and lead time?
A: MOQ 5 tons (stock sizes), 15-25 days production for custom orders.
