Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : As long as railroad tank car interiors have been coated or lined to preclude interaction of their contents with the steel vessel, there have been multiple approaches to the stewardship of the lining. (In rail-industry parlance, the word “lining” is often used to refer to both interior coatings [spray-applied] and interior linings [applied in sheets].) Since the adoption of regulations that require systematic assessment and maintenance of linings under certain conditions, a consensual mindset and practices have gradually evolved in the industry. This article explores that evolution including past and present norms. Note de contenu : - Corrosive cargo
- The tipping point
- New rules arise
- The state of stewardship today
- Additional thoughts
- Looking ahead

Fig. 3 (left). Some coating distress is due simply to mechanically-inflicted damage. Fig. 4 (right): A spontaneous breach in a medium-film epoxy leads to rapid pitting corrosion

Fig. 6. If railroad tank car coatings are not diligently examined and maintained, the tank shell can be reduced in thickness or even perforated
Fig. 7 (left). The reasons for a spontaneous coating failure may never be entirely understood, but addressing the condition promptly will prevent consequent tank distress. Fig. 8 (right): The “heel” left behind in a tank car bottom may be especially damaging to an interior coating
Fig. 9. On rare occasions, a commodity/coating pairing may turn out to be wholly inadequate
Fig. 10. Some ladings separate into two or more distinct layers in transit, each of which may act in a different way on the coating
Fig. 11. Existing "nuisance" corrosion can shorten the life of even the best-applied subsequent coating
