Product Details
Steel pipes are some of the most important components in any type of industry. Being used to transport liquids, substances, and currents across different locations, pipes are placed in important components and machinery, ensuring they have a secure channel and network to operate effectively. Due to these substances being strong and volatile, it is important that these pipes are made out of highly durable material.
This led to the use of steel, which is one of the strongest materials used in various industries across the world. Known for being highly resistant against extreme temperatures and conditions, using steel ensures the pipes would not wear down or break during use. There are many types of steel used to make these pipes, and one of the best types used in the industry are galvanized steel pipes. The Advantages of galvanized steel pipe
1.Low processing fee
Galvanized pipe anti-rust cost is lower than other paint coatings
2. Durable
In the suburban environment, the anti-rust thickness of the standard galvanized steel pipe can be maintained for more than 50 years without repair; in urban or offshore areas, the standard anti-rust layer of the galvanized pipe can be maintained for 20 years without repair
3. Strong coating toughness
The galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use
4.Good reliability
The galvanized layer forms a metallurgical bond with the steel and becomes a part of the steel surface, and the durability of the coating is more reliable
5. Comprehensive protection
Every part of the electroplated parts can be galvanized, even the depressions, sharp corners and hidden places can be fully protected
6. Low initial cost
In general, the cost of galvanized pipe is lower than that of applying other protective coatings, mainly because the process of galvanized pipe is more mechanized and more efficient
7. Save time and effort
The galvanizing process is faster than other coating application methods and can avoid the time required to paint on site after installation
8.Checking is simple and convenient
The galvanized layer can be detected by visual inspection and simple non-destructive coating thickness gauge, which is convenient for inspection Process Flow
The production of galvanized pipes requires the use of steel pipes (such as ms seamless pipes) as the base material. Coating a layer of zinc on the surface of the steel pipe can effectively prevent the steel pipe from being oxidized and corroded. Therefore, the production process of galvanized pipe is mainly divided into the following steps:
1. Pretreatment of steel pipe
Before steel pipes are galvanized, they need to be pretreated. First, clean the oil and impurities on the surface of the steel pipe to ensure that the zinc layer can be firmly attached to the surface of the steel pipe. Secondly, the steel pipe is pickled to remove oxides and rust on the surface.
2. Galvanized
After the steel pipe surface is pretreated, it can be galvanized. There are two methods of galvanizing: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing is to immerse the steel pipe in molten zinc, so that the zinc reacts with the surface of the steel pipe to form a layer of zinc. Electrogalvanizing is to immerse the steel pipe in the electrolyte solution containing zinc ions, and the zinc ions are reduced to a zinc layer on the surface of the steel pipe by the action of electric current.
3. Inspection
After the galvanizing is completed, the steel pipe needs to be inspected. Mainly check whether the zinc layer on the surface of the steel pipe is uniform, whether there are defects and bubbles, etc. If there is a problem, it needs to be repaired or re-galvanized.
4. Packaging
Pack the galvanized steel pipes. It is usually packed in plastic bags or cartons to protect the zinc layer on the surface of the steel pipe from damage. The production process of galvanized pipe needs to go through multiple steps, including pretreatment of steel pipe, galvanizing, inspection and packaging. Through these steps, galvanized pipe products with good quality and good anti-corrosion performance can be produced.
