Advantages of hot-dip galvanized steel pipe

Hot-dip galvanized steel pipe is used in production and life. Hot-dip galvanized steel pipe has excellent corrosion resistance, convenient transportation and relatively low price, and it has an irreplaceable position in the galvanized square tube suppliers. So why use hot-dip galvanized steel pipes, and what are the advantages?

  1. Low processing cost: the cost of hot dip galvanizing rust is lower than that of other paint coatings;
  2. Durable: The thickness of zinc galvanized steel pipe is up to standard. In the suburban environment, the standard galvanized rust thickness can be maintained for more than 50 years without repairing; in urban or offshore areas, standard hot-dip galvanizing rust The layer can be kept for 20 years without having to repair it;
  3. 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 relatively reliable;
  4. Strong toughness of the coating: The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use;
  5. Comprehensive protection: Hot-dip galvanized steel 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 each position of the inner and outer surfaces of the steel pipe can be fully protected;
  6. Save time and effort: The galvanizing process is faster than other coating methods and can reduce the time required to apply on the construction site after installation.
  7. Low initial cost: Under normal circumstances, the cost of hot dip zinc is lower than that of other protective coatings, because other protective coatings such as sanding paint are labor intensive processes, while hot dip zinc is highly mechanized and compact. Controlled in-plant construction.
  8. Simple and convenient inspection: hot dip galvanized layer can be tested visually and simply non-destructive coating thickness gauge
  9. Reliability: The hot-dip galvanized steel pipe is strictly in accordance with GB/T3091-2008, and the minimum zinc layer thickness is limited, and the corresponding experiment, so the rust-proof period and performance are reliable and predictable.
  10. Safety: The hot-dip galvanized steel pipe has passed the international green system certification such as ISO90001 quality management system, ISO14001 environmental management system and OHSAS18001 occupational health and safety management system, special equipment manufacturing license, etc., and each steel pipe must be strictly used. Water pressure test, and the use of chrome-free passivation after galvanizing will not affect the environment, ensuring that each steel pipe can be used with peace of mind.
