What is the primary cause of denting in propane cylinders?

The primary cause of denting in propane cylinders is indeed related to improper handling or impacts during transport. When propane cylinders are not handled with care, they can be dropped, knocked against hard surfaces, or otherwise subjected to forceful impacts. Such physical stress can lead to dents or deformities in the cylinder’s structure.

Transporting propane cylinders requires adherence to safety protocols to ensure that they are stable and secure. Factors like inadequate securing of the cylinders during transport or mishandling while loading and unloading can contribute significantly to denting, affecting the cylinder's integrity and safety.

While excessive temperature changes, exposure to harsh weather conditions, and overfilling can lead to other types of issues or risks associated with propane safety, they do not directly cause the physical denting seen in cylinders. Temperature fluctuations and harsh conditions may affect the performance and safety of the propane system but are not linked to impacting the external structure of the cylinder like improper handling is.
