Galvanized pipe: Hot-dip galvanized pipe is to make the molten
metal react with the iron matrix to produce an alloy layer, so that
the matrix and the coating are combined. Complicated physical and
chemical reactions occur between the steel pipe matrix and the
molten plating solution to form a corrosion-resistant zinc-iron
alloy layer with a compact structure. The alloy layer is integrated
with the pure zinc layer and the steel pipe matrix. It has the
advantages of uniform coating, strong adhesion and long service
life.
Main uses and industries: widely used in low-pressure fluid
delivery and mechanical structures such as fire water supply, gas,
air, oil, heating steam, etc.
Welded steel pipe for low pressure fluid transportation Galvanized
Steel round pipe Features
- Low processing cost: the cost of hot-dip galvanizing and rust
prevention is lower than that of other paint coatings;
- Durable and durable: the thickness of the zinc layer of the hot-dip
galvanized steel pipe meets the standard. In the suburban
environment, the standard hot-dip galvanized anti-rust thickness
can be maintained for more than 50 years without repairing; in the
urban area or offshore areas, the standard hot-dip galvanized
anti-rust thickness The layer can be maintained for 20 years
without repairing.
- Good reliability: The galvanized layer and the steel are
metallurgically bonded and become a part of the steel surface, so
the durability of the coating is more reliable.
- Strong toughness of the coating: The galvanized layer forms a
special metallurgical structure that can withstand mechanical
damage during transportation and use.
- Protection: The hot-dip galvanized pipe uses high-pressure air to
control the uniformity of the zinc layer on the inner and outer
surfaces of the steel pipe, so that every position on the inner and
outer surfaces of the steel pipe can be protected.
- Time-saving and labor-saving: the galvanizing process is faster
than other coating construction methods, and can reduce the time
required for painting on the site after installation.
