Despite weighing just 5 tons, this stainless steel heat exchanger consists of 840 tubes . More than 1,700 pressure part welds were required, with 100% X-ray inspection. Other special requirements included a greater minimum wall thickness, very close tube pitch, numerous inspection openings, acceptance in accordance with ASME and PED, and additional pressure and leakage tests for the pressure part and the casing.
Excellent communication and cooperation was key to the success of this complex project!
