Product Introduction
Dongmeng DN50 2 Inch Galvanized Pipe 10ft 20ft GB ASTM Cold Rolled
Galvanized steel pipe is an alloy layer formed by the reaction between molten metal and iron matrix, which combines the matrix and the coating. Hot-dip galvanizing is a process of pickling steel pipes. In order to remove the iron oxide on the surface of steel pipes, after pickling, the pipes are cleaned through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent into the hot-dip galvanizing tank.Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the steel tube matrix and the molten plating solution, resulting in a zinc-iron alloy layer with a close corrosion resistance structure. The alloy layer is integrated with pure zinc layer and steel tube matrix. Therefore, it has strong corrosion resistance. Galvanized steel pipe are widely used, in addition to pipelines for general low-pressure fluids such as water, gas, oil, etc., and also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensation of chemical coking equipment. Cooler, coal distillate oil exchanger pipe, and trestle pipe pile, support pipe for mine tunnel, etc.

Normal spangle
Through addition of certain heavy metal element into molten zinc bath, regular spangle pattern is produced on Hot-dip zinc-coated steel sheet.
Minimized spangle
The zinc layer(coating) does Not contain Lead(Pb), which complies with EU WEEE and RoHS directives. This is a non-toxic and environmental friendly material.
Spangle-free
During hot-dip galvanizing, only a certain amount of aluminum is added to the zinc solution, and lead-free, antimony, and tin are not added to produce spangle-free products.

Application
Dongmeng DN50 2 Inch Galvanized Pipe 10ft 20ft GB ASTM Cold Rolled
Galvanized Steel Pipe/Tube products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and other industries. Such as building roofs, highway guardrails, sheet metal processing, roof grilles, household appliance enclosures, ventilation ducts, chimneys, kitchen utensils, grain storage and transportation, frozen processing of meat and aquatic products, etc.

Main Features of Galvanized Steel

Anticorrosive: 13 years in heavy industrial areas, 50 years in the ocean, 104 years in the suburbs and 30 years in cities.
Cheap: The cost of hot-dip galvanizing is lower than that of other coatings.
Reliable: The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more
durable.
Strong toughness: The galvanized steel sheet layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
Comprehensive protection: Every part of the plated piece can be galvanized, and is fully protected even in depressions,sharp corners,and hidden places.
Save time and energy: Galvanizing process is faster than other coating methods.
