What is galvanized steel pipe?
Galvanized steel pipes welded with hot dip or electrogalvanized coating on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong the service life. Galvanized pipe USES is very wide, in addition to a general low pressure fluid such as water, gas, oil line pipe, also used as oil industry, especially the ocean oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for pipe, and trestle pile, mining tunnel supporting frame pipe, etc.
Hot dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
Cold galvanizing is electric galvanizing. The amount of galvanizing is very little, only 10-50GM2. Its corrosion resistance is generally more than that of hot galvanized pipe. Cold galvanized wire grooves commonly used in electrical applications. Regular galvanized pipe manufacturers, in order to ensure quality, most do not use galvanized. Only those small enterprises with obsolete equipment use electrogalvanizing, of course, their price is relatively cheaper. The Ministry of Construction has officially below, the elimination of cold galvanized pipe technology behind, not allowed to use cold galvanized pipe for water, gas pipe.

6 diameter galvanized steel pipe:
In engineering, 1 inch equals 25.4 mm, Steel pipe with a diameter of 6 inches is 150 mm.
Galvanized steel that has a hollow section and is much longer than its diameter or circumference. According to the shape of the section, it is divided into round, square, rectangular and special-shaped steel pipes. According to the material, it is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe. According to the purpose, it is divided into conveying pipeline, engineering structure, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high pressure equipment steel pipe, etc.

Effect on the properties of galvanized pipe:
In order to improve corrosion resistance, the general steel pipe (black pipe) is galvanized. Galvanized steel pipe is divided into two kinds of hot dip galvanized and electric steel zinc, hot dip galvanized galvanized layer is thick, electric galvanized cost is low, so there are galvanized steel pipe.
1. Carbon: The higher the carbon content, the harder the steel, but the less plastic and ductile it is.
2. Sulfur: Is the harmful debris in steel, high sulfur steel at high temperature for pressure processing, easy to crack, usually called hot brittle.
3. Phosphorus: Can make the plasticity and toughness of steel significantly decreased, especially at low temperature is more serious, this phenomenon is called cold brittleness. In high quality steel, sulfur and phosphorus should be strictly controlled. On the other hand, the higher sulfur and phosphorus in low carbon steel can make it easy to break, which is beneficial to improve the machinability of steel.
4. Manganese: Can improve the strength of steel, can weaken and eliminate the adverse effect of sulfur, and can improve the hardenability of steel, high manganese content of high alloy steel (high manganese steel) has good wear resistance and other physical properties.
5. Silicon: It can improve the hardness of steel, but plasticity and toughness decline, electrical steel contains a certain amount of silicon, can improve the soft magnetic properties.
6. Tungsten: Can improve the red hardness and thermal strength of steel, and can improve the wear resistance of steel.
7. Chromium: It can improve the hardenability and wear resistance of steel, and improve the corrosion resistance and oxidation resistance of steel.

How long of hot galvanized steel pipe lifetime?
Galvanized steel pipe have long lifetime. But in different conditions the lifetime of use are different. Generally speaking, 13 years in heavy industrial district, 50 years for ocean environment, 104 years in suburbs, 30 years in city. In fact galvanizing have played a role of anti- rusty, it is no need other rust treatment. Hot galvanizing process specially suitable for kinds of strong-acid, alkali fog and other strong corrosive conditions. This kinds of fastener used a lot in outside of steel tower contribution.
Cold galvanization technology is no longer recommend for pipe products.
For more thinner zinc layer reason, countries of the world have gradually forbidding the cold galvanized steel pipe as water pipe and coal gas pipe. But due to cold galvanizing processing have smooth appearance of surface, it always used in manufacturing small pieces which requiring precise plating. Such as screws, Machinery manufacturing, electronics, precision instruments, chemicals, light industry, transportation, weapons, aerospace, atomic energy, etc., in the national economy has great significance.
