Types of Galvanized Steel Pipe

large enterprise scale

Hot–dip galvanized is the process of placing pre-treated pipe into molten zinc at around 450°C to form a strong galvanizing layer outside the pipe. Under normal circumstances, hot–dip galvanizing is considered to have a longer service life.

Pre-Galvanized (Pre-Galvanized Pipes)

Pre-galvanized is the steel through the cold rolling machine processing, the use of electrochemical method galvanized, and then the pre-galvanized steel coil, welding, molding, reprocessing, galvanized steel pipe.

Process Characteristics of Galvanized Steel Pipe

Because the coating crystallization is not fine enough, the deep plating ability is poor, and it is only suitable for pipes and wires with simple geometric shapes.

After process improvement, iron salts were added to the original solution, which not only inherited the advantages of traditional sulfate galvanizing but also enhanced the ability of deep plating.

After continuous improvement, the coating grains used for wires and pipes are more delicate and shiny than before.

Bending Test of Galvanized Steel Pipe

Test method:

A section of the pipe is typically clamped at specific points and then gradually bent using a controlled force until a predetermined bend angle is reached, or until failure occurs.

Notes

Bend radius: The bending radius used in the test is critical, as a tighter bend will put more stress on the pipe and coating.
Test standards: Specific parameters like bend angle, loading rate, and sample size are usually defined by relevant industry standards.

Application Scope of Galvanized Steel Pipe

Application in agriculture

• Galvanized steel pipe has good rust resistance, variety of sizes, easy to shape and install, so it is widely used in irrigation systems.
• Black steel pipes, hot-dip galvanized steel pipes are also widely used in animal husbandry. Large steel pipes are used to make feed or waste pipes for livestock and poultry.
• In the fishery, fish farming cages are made from hot-dip galvanized steel pipes, replacing bamboo cages, overcoming limitations in rust resistance, life expectancy and cage breakage when there are large underground waves.

Applications in plumbing

Steel pipes are widely utilized in water supply and drainage systems, high pressure plumbing installations or outdoor water supply networks. The nature of these projects all need large load capacity, easy to bend, shape according to the terrain, installation location, so galvanized steel pipe is the most appropriate option.

Applications in telecommunications

The telecommunications system is the basic of social communication. Many telecommunications forms are utilized galvanized steel pipes to product public lighting, ultrasonic pile systems, broadcasting piles, telecommunications poles, phone wiring, equipment boxes,...

Application in construction

The application of galvanized steel pipes in the construction field must be mentioned as the key materials for housing and civil works such as rails, gutters, fences,... These steel pipes are shiny galvanized, aesthetics and durability, suitable for outdoor applications.

FAQ

Q: What is the difference between black steel pipe and galvanized steel pipe?

A: Black steel pipe and galvanized steel pipe have a clear difference in cost because in the production process, manufacturers have to perform additional galvanizing steps for steel, so the cost to sell to the market will be higher than that of black steel pipe. In addition, during time for implementing the construction or commercial buildings, galvanized steel pipes will never be connected to black steel pipes.

Q: How long does galvanized steel pipe last?

A: Galvanized steel pipes were originally expected to last 50 to 70 years, but many corrode after 40 years.

Q: Can you run drinking water through galvanized steel pipe?

A: Galvanized steel pipes can be used as drinking water pipes, but the water must be boiled for drinking. However, after a long time of use, the lead and zinc in the galvanized pipe will precipitate into the water, and the pipe wall is prone to scale.

Q: What issues should be paid attention to during the use of galvanized steel pipe?

A: During installation, you need to ensure that the pipe connection is firm and the sealing is good; during maintenance, you need to regularly check whether the zinc layer of the pipe is intact, and if there is any damage, it should be repaired in time; during maintenance, you need to take appropriate anti-corrosion measures to extend the service life of the pipe.

Q: What are the main uses of galvanized steel pipe?

A: Galvanized steel pipe is widely used in many fields, including construction, chemical industry, petroleum, machinery, etc. In the construction industry, it is often used to build scaffolding, support structures and transport fluids; in the chemical and petroleum industries, it is used to transport various corrosive media and high-temperature fluids.

Q: What are the specifications and sizes of galvanized steel pipe?

A: Common galvanized steel pipe specifications include steel pipes of different diameters and wall thicknesses, as well as pipe sections of different lengths. In addition, there are some special shapes of galvanized steel pipes, such as square and rectangular.

Q: What is the corrosion resistance of galvanized steel pipe?

A: Generally speaking, the thicker and more uniform the zinc layer, the better the corrosion resistance of the steel pipe. The corrosion resistance of hot-dip galvanized steel pipes can usually meet the use requirements in a variety of harsh environments.
