2002: 13 years after installation

This fuel gas line is always wet (the green coloration is mold) and the beam paint system has failed, but no corrosion has occurred at the pipe support.

2017: 28 years after installation

28 years after installation, the fuel gas line shows minor paint failure at the support but the I-Rod is still intact.
