Double Groove & Expansion Type Heat Exchanger

Tight, durable seating of tubes in tube sheets is one of the critical functions in manufacturing heat exchangers for high pressure steam generators, boilers for conventional power generation, food and pharmaceutical processing systems and condensers. In selecting the best method for expanding the tube within the sheet, we examine factors including safety, speed, cost, operator skill requirements, repeatability and overall quality.With the number of tubes in a sheet ranging from the hundreds to tens of thousands, and the expansion process being done manually one by one, the stakes for achieving the best balance of quality and cost are high.Our Heat exchanger have an excellent joint strength and tightness is that a stick interface and high residual interfacial force are obtained between the tube and tube sheet.
