Disappointing New Plate Heat Exchanger

We have waited for the new heat exchanger for more than 6 months. It safely arrived last month. We managed to installed the heat exchanger and connect the pipeline. Thanks to the hard work by the maintenance fitters. The insulation work for the pipeline is in progress. That is important to avoid heat and energy lost. Everybody was eager to use the new heat exchanger. We installed pressure gauges, pressure transmitters, RTDs and temperature gauges along the new line. We fixed ball valves and bellow seal globe valves. We performed air test. Everything seems good and promising. We finally used the heat exchanger few days ago. Unfortunately it leaks and we have to stop it. We tightened the plate heat exchanger. Run it again, but it still leaks. We stop it and retightened it again, and run the heat exchanger. It still leaks. It leaked at the end of the plate next to the frame. We suspected the end plate is leaking and it don't look good. Maybe the gasket is glued unevenly to the plate surface. We were so furious because a new plate heat exchanger that just arrived from Germany is leaking. Is this a manufacturing defect? Lets see what's going to happen tomorrow.
