Upon inspection, Redwood determined that both idler rollers were made of yellow polyurethane, with one roller having a durometer of 80 and the other having a durometer of 40. Due to their application in a hot welding environment, both rollers suffered from rippling effects due to their constant exposure to high temperatures. The customer requested that Redwood recoat the rollers at a strong enough durometer to withstand the high temperatures they are constantly exposed to. After some deliberation, the customer determined this optimal recoat durometer to be 60D.
In partnership with another company, we began the recoating process by incinerating the old material off the core. Next, Redwood’s team of experts used a steel-formed ring built in-house to cast the rollers in 60D urethane. By performing this recoat, the customer’s rollers were now able to withstand the weight of the pressure vessels without succumbing to the heat’s rippling and reverting effects.
