Purchase Tips for Purchasing of Galvanized Pipes - Cleaning and Maintenance of Galvanized Pipes Introduction and Functions of Galvanized Pipes, also known as galvanized steel pipes, are divided into hot-dip galvanized and electro-galvanized. Among them, the hot-dip galvanized galvanized layer is thick, with the advantages of uniform coating, strong adhesion and long service life. Electrogalvanizing is low in cost and not very smooth on the surface. Its corrosion resistance is much worse than that of hot-dip galvanized pipes.
Most old houses use galvanized pipes. The iron pipes used for gas and heating are also galvanized pipes. As a water pipe, galvanized pipes are used as water pipes. After a few years of use, a large amount of rust and dirt will be generated in the pipes. The yellow water flowing out not only pollutes the sanitary ware, but also is mixed with bacteria growing from the non-smooth inner walls. The corrosion causes the heavy metal content in the water to be too high, which seriously endangers the health of the human body. In the 1960s and 1970s, developed countries in the world began to develop new types of pipes and gradually banned galvanized pipes. The Ministry of Construction and four other ministries and commissions of China have also issued documents to clarify that galvanized pipes will be banned from 2000. At present, galvanized pipes are rarely used in cold water pipes in newly built communities, and some communities use galvanized pipes.
The commonly-called galvanized pipe is now mainly used to transport gas and heating. As a water pipe, galvanized pipes are used for a few years, a large amount of rust and stains are generated in the pipe. The outflow of yellow water not only pollutes the sanitary ware, but also contains bacteria that grow from the non-smooth inner wall. Rust causes too high heavy metal content in the water, which seriously endangers the health of the human body. In the 1960s and 1970s, developed countries in the world began to develop new types of pipes and gradually banned galvanized pipes. China's Ministry of Construction and four other ministries have also issued documents to clarify that galvanized pipes will be banned from 2000.
Purchase tips for galvanized pipes
Zinc does not change much in dry air. If a layer of zinc is coated on the surface of the steel pipe, it can prevent the steel pipe from being corroded. We call a type of steel pipe galvanized pipe. Galvanized pipes have relatively excellent performance compared to other ordinary steel pipes.
When purchasing galvanized pipes, you can choose according to the following days:
1. Smooth appearance, no zinc tumors, burrs, and silver-white;
2. No hydrogen embrittlement, no temperature hazard, which can ensure that the mechanical properties of the material remain unchanged;
3. It can replace some of the process that requires hot-dip galvanization;
4. Good corrosion resistance, neutral salt spray test reaches 240 hours. Cleaning and Maintenance of galvanized pipes When cleaning galvanized pipes, it is necessary to avoid adding detergent to the water. When cleaning, many people don’t know the truth very well. Using powerful detergents to remove stains is actually not scientific enough.
There will be a coating on the outside of the galvanized pipe, and the cleaning agent will be low in the friction between the brush and the guardrail, which will affect the cleaning effect. Moreover, the chemical substances contained in it will directly cause the outer layer to fall off, which will directly reduce the service life of the galvanized pipe and reduce the safety effect.
