Yes, these items may require some form of maintenance, particularly in industrial applications where corrosion is likely to be a problem. Occasional inspection of the tubes and pipes for corrosion and wear is advisable to ensure that the system is safe and at optimal performance levels. In case there are possibilities of surface contaminants, you may want to gently clean the surface. For hydraulic systems and air separation equipment that may feature seals, consider adding some lubricant. The goal of these and other maintenance activities is to prevent/slow down wear of the aluminum seamless tubing for the safe and economical use of large-diameter seamless tubes and pipes.
