CuZn30 seamless copper tube preservation method
1. dry and ventilated: the environment for storing CuZn30 copper tube should be kept dry and ventilated to avoid moisture and corrosion.
2. Antirust treatment: Before storage, it can be treated with antirust treatment, such as coated with antirust oil or wrapped with antirust paper.
3. Avoid collision: avoid heavy objects pressing on the copper pipe when stacking to prevent deformation and damage.
4. Regular inspection: check the surface condition of copper pipe regularly, and deal with corrosion or damage in time.
