In order to ensure its performance and extend its service life, the
maintenance and cleaning operations of nickel alloy pipe fittings
need to pay attention to the following aspects:
Clean:
1. Use mild cleaners: Avoid using cleaners containing chlorine, phosphoric acid, or
sulfuric acid, as these chemicals can damage the surface of nickel
alloys.
2. Use a soft cloth or non-abrasive sponge: Avoid using abrasive cleaning tools such as steel wool, which may
scratch the surface of the fitting.
3. Frequency of cleaning: Depending on the usage environment, clean regularly to remove
dirt and corrosion that may have accumulated.
Examine:
1. Regular Inspections: Regularly inspect pipe fittings for any visible damage, such as
scratches, cracks, or corrosion.
2. Check connections: Make sure all connections are tight to prevent leaks.
Anti-corrosion measures:
1. Coating protection: Apply anti-corrosion coating or anodic protection to the surface
of pipe fittings to enhance its corrosion resistance.
2. Avoid Exposure to Moisture: Minimize exposure of pipe fittings to high humidity or moisture,
as this may accelerate the corrosion process.
Installation and maintenance:
1. Proper installation: Make sure pipe fittings are installed correctly according to the
manufacturer's instructions to avoid damage caused by improper
installation.
2. Use the right tools: Use the right tools during installation or maintenance and avoid
using excessive force to avoid damaging the fittings.
Storage:
1. Dry storage: When storing nickel alloy pipe fittings, ensure that the storage
environment is dry and avoid direct exposure to sunlight or humid
places.
2. Avoid stacking: Do not stack heavy objects on fittings to prevent deformation or
damage.
Professional maintenance:
1. Regular professional inspections: For critical or high-demand systems, regular inspection and
maintenance by professionals is recommended.
Following these maintenance and cleaning precautions can help
ensure that nickel alloy pipe fittings maintain optimal performance
and corrosion resistance throughout their expected service life.
