22. Protecting molten sulfur tank cars (Feat. Lupe Pavon and Steve Liebhart)

Summary 

Sulfur, an instrumental commodity to global industry, is a highly corrosive commodity typically shipped via rail in a molten state. Shippers must take care to protect their rolling stock by applying linings that resist heat, chemicals, and impacts. In this episode, rail industry expert Lupe Pavon and tank lining expert Steve Liebhart explore service environment, cleaning/surface preparation, and protective lining principles for rail cars in molten sulfur service. They also relate interesting findings from a field inspection. And, Steve considers himself a near-perfect driver in the snow, and Lupe reveals his favorite vegetable. **Timestamps **
