Emergency Calls -- PT&P Solutions

Case #1

An Alaskan petroleum firm called upon the PT&P Field Service Team on a Friday evening to aid them in an immediate replacement of a defective 48" dia. expansion joint. The expansion joint was damaged during the plant startup when a G417 pump suddenly failed. A replacement expansion joint was designed, manufactured, and shipped the next day. It was installed at the customer's location within 2 days of receiving the call.
