Service life and maintenance methods of galvanized pipes 

The service life of galvanized pipes is affected by many factors, and is generally around 10-20 years. Correct maintenance can extend the service life.

Service life of galvanized pipes

Galvanized pipe is a general building material that can be used for water supply, gas, heating and drainage. The service life is generally around 10-20 years, but it depends on the following factors:

1. Usage environment: Galvanized pipes are easily damaged in environments such as moisture, corrosion, acid, alkali or high temperature, thus shortening their service life.

2. Usage: If galvanized pipes are used as sprinkler systems, there will be many water droplets inside the pipes. Long-term use will cause rust and blockage inside the pipes, thus affecting the service life.

3. Copper interfaces and welded interfaces: Copper interfaces and welded interfaces will destroy the zinc layer of galvanized pipes, thereby affecting their anti-corrosion capabilities and causing pipeline corrosion.

4. Maintenance: Without correct care and maintenance, galvanized pipes are more likely to fail and have a shorter service life.

Maintenance methods of galvanized pipes

Correct maintenance methods can extend the service life of galvanized pipes.

1. During installation: Before installing galvanized pipes, the inside of the pipes must be spray-painted to reduce the chance of contact with moisture and oxygen in the pipes, making the exterior and inner walls relatively smooth and smooth.

2. During use: Galvanized pipes should be cleaned during use and dirt on the inner wall of the pipe should be removed regularly. In addition, it is forbidden to mix chemical water into galvanized water pipes, otherwise it will accelerate the corrosion of the zinc layer.

3. Regular inspection: Regularly check galvanized pipes for damage, leakage, corrosion, etc. If problems are found, they should be repaired and replaced in time.

4. Preventive measures: When using galvanized pipes, care should be taken to avoid mechanical injuries such as handling and collision. At the same time, prevent excessive stress on the pipeline to avoid deformation and loose fittings.
