Heat exchanger tubes are constantly expanding and contracting as they heat up and cool down during normal operations. Depending on the application, saltwater, calcium, Lyme, and other contaminants can compound the problem, leading to even faster deterioration. Over time, these factors inevitably lead to failure and the tubing must be replaced. Maayear global engineering petroleum services offers a complete, on site heat exchanger, re-tubing service. We re-tube and repair heat exchangers from most major manufacturers. Our technicians - Remove damaged, corroded, or worn-out tubes - Clean and prep tube sheets - Provide the replacement tubes you need (or work with customer-supplied tubes) - Install new tubing - Assist in pressure or hydro testing the heat exchanger - Evacuate, charge, and restart the system.
