Galvanized Steel Pipe

Your Leading Galvanized Steel Pipe Supplier

Tangshan Zhenxiang Plate and Strip Processing Co., Ltd. has become a comprehensive steel enterprise integrating plate and strip longitudinal shearing, hot-dip galvanizing processing, machinery purchase and trading, and logistics distribution. Galvanized steel pipe is a type of steel pipe that has been coated with a layer of zinc to protect it from corrosion and rust. Galvanizing is the process that involves covering steel pipes with a protective zinc layer. This zinc coating functions as a shield against rust; thus, so galvanized steel pipes do not wear out even when subjected to very tough atmospheric conditions.

Types of Galvanized Steel Pipe

Hot Dipped Galvanized Steel Pipe

Hot dipped galvanized steel pipe is coated with a layer of zinc on the surface, which can effectively prevent the oxidation corrosion of the pipe and prolong its service life. It is especially suitable for humid or corrosive environments (such as chemical plants, marine climates, etc.).

1 Inch Gi Square Pipe

1 inch gi square pipe is steel pipe that has been treated with a special coating process that prevents corrosion and prolongs its service life. The coating is usually made of zinc and is applied through a process called hot-dip galvanizing. These pipes are often used in plumbing, building and structural applications.

Square Hollow Section

Square hollow section is coated with zinc to prevent oxidation and rust, which ultimately prevents pipe damage. Galvanized steel pipe is a good choice when you need to protect steel pipe from corrosive environments.

The Process of Galvanized Steel Pipes

Metal Preparation
Before anything else, the iron pipes firstly go through a meticulous surface preparation. There are a number of steps the base metal has to undergo before reaching the galvanizing process. These all ensure that the iron is prepared for the next step.

Dipping Phase into Molten Zinc
Although all parts are important in the galvanizing process, this is step and technique are what make it so popular. Here, the iron pipes are generously immersed in a bath of molten zinc of around 449 degrees Celsius or 840 degrees Fahrenheit. Here, it will alloy a thick and robust layer on the surface of the base metal.

Cooling, Finishing, and Drying
After the zinc dipping technique is done, it is now time for the galvanized iron pipes to cool down. Typically, the galvanized iron pipes are cooled in a quench tank for it to cool down quickly and restrain unwanted effects of the newly formed coating with the atmosphere of its surroundings.

Quality Control
Just like all manufactured products undergo strict quality control too. Here, the galvanized iron pipes are checked and determined if they are within specifications for the final product.

Hardness Test of Galvanized Steel Pipe

Mohs hardness
When comes to hardness, most people are familiar with the Mohs hardness scale. This system determines the hardness based upon surface wear – scratching one material with other materials. If material A can scratch material B, then material A is harder than B.

Rockwell hardness
The Rockwell hardness method compares two indentations made in a material. One made with a small load, and the other with a large load. A unique feature of the Rockwell scale is that it correlates linearly with material tensile strength; Rockwell hardness is generally reserved for harder materials.

Brinell hardness
The Brinell hardness scale is a widely accepted measure of hardness in materials. It involves pressing a ball of steel into the test piece at a constant and known force. The softer the material, the deeper the ball will penetrate and vice versa. The next step is to take a measurement of the diameter of the resulting impression, followed by a calculation, typically in megapascals, to determine the Brinell hardness scale.

Applications of Galvanized Steel Pipe

Applications in solar energy
The zinc coating on the outside of the steel pipes has a comprehensive protection effect, increasing the long term use of the frame system. Therefore, galvanized steel, especially pipe steel, box steel, V-shaped steel, etc. are often chosen as frames for solar power systems.

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. Large steel pipes are used to make feed or waste pipes for livestock and poultry.

Applications in plumbing
Steel pipes are widely utilized in water supply and drainage systems, high pressure plumbing installations or outdoor water supply networks. Square or rectangular galvanized steel pipes are also used for ventilation systems, assembling house frames, scaffolding, bearing trusses, etc.

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, etc.

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, etc. These steel pipes are shiny galvanized, aesthetics and durability, suitable for outdoor applications.
