Precautions for the use of galvanized steel pipes, industrial transportation and construction industries are inseparable from the use of galvanized steel pipes, including the use of galvanized steel pipes in agricultural greenhouse construction, because galvanized steel pipes are more durable, and galvanized pipes can prevent corrosion. Extending the service life greatly saves money and ensures safe use. There are several precautions for the use of galvanized steel pipe.
The service life of galvanized steel pipe can be as long as 15-30 years due to the appearance of galvanizing. The process of galvanized steel pipe is mainly divided into three parts:
The first part is to first treat the steel pipe to be galvanized, and decontaminate it with acid to achieve a clean and bright surface. At this time, the next work can be done.
The second part is to clean with chemical solvent, and then put it into the hot-dip galvanizing tank for galvanizing work, which is also a very important step.
The third part is to coil the galvanized steel pipe into a coil and put it into the warehouse, and process it when it is needed or when a merchant buys it.
The types of galvanized steel pipes can be divided into hot-dip galvanized steel pipes and cold-galvanized steel pipes.
Galvanized steel pipe is not recommended to be used for food. Eating too much galvanized steel is bad for your health. It can be used in fire fighting, bathing, watering flowers, etc.
A large number of chemicals such as strong acids, strong bases, salts and organic solvents are used in electroplating production. During the operation, a large amount of toxic and harmful gases will be emitted. If the safety management work is not done well, poisoning, burns, and even burning explosion accident.
The specification for the use of galvanized steel pipes for fire-fighting pipelines is based on the national standard GB/T3091-2008 "Welded Steel Pipes for Low-Pressure Fluid Transport". Dimensions, Shapes, Weights and Tolerances".
There are no strict regulations in the state, and it is generally determined by the design unit. When the design unit only gives DN××, it should be clarified during the joint review, so as to avoid conflicts between the construction unit and the installation unit during settlement. In my opinion, it is better to use the market specifications. For DN100, it can be more than 4mm, because the pressure of fire water can be tolerated.
Here are the precautions for the use of galvanized steel pipes. There are many ways to use galvanized steel pipes. We need to understand some details. If you have any questions about the use of galvanized steel pipes, you can contact our technical staff.
