1. Check whether it is corrosion-resistant and confirm that there is no excessive exudate.
2. It is better for the manufacturer to come up with the data report of the corrosion test, which is more convincing.
3. If it is used for hot water pipes, the thermal conductivity should also be considered, and the low thermal conductivity has good thermal insulation performance.
4. Whether the strength is sufficient, the general color-coated plate and color steel plate can reach the strength to withstand the impact of high-speed water flow of 30 meters per second.
