What is the maximum temperature of heated air used to dry a cylinder after hydrotesting?

The maximum temperature of heated air used to dry a cylinder after hydrotesting is 150 degrees. This temperature is established to ensure effective drying without risking damage to the cylinder or compromising its integrity. When drying cylinders after hydrotesting, maintaining a moderate temperature is crucial, as excessive heat can negatively affect the materials used in the cylinder and could lead to structural weakening or failure.

Using heated air at or below 150 degrees helps to rapidly evaporate any residual moisture while ensuring that the drying process is safe and controlled. Higher temperatures might not only risk damaging the cylinder itself but could also pose safety hazards for personnel handling the equipment. Therefore, the 150-degree standard strikes an effective balance between efficiency in the drying process and safety in material handling. This consideration is essential in the context of maintaining compliance with safety regulations and best practices in cylinder maintenance.
