NENSHELL AND TUBES

Shell and tubes heat exchanger according to TEMA NEN standard. This design with removable back end flanges allows tube side inspection without dismantling the heat exchanger from the pipeline.

According to the design temperature and pressure conditions and fluids process, materials are selected from all metals available like: austenitic stainless steels, duplex, high temperature resistance steels, superaustenitic, exotic alloys (Inconel, Incolloy, Monel, Hastelloy), titanium alloys (grade 1, 2, 3, 4, 7 and 11), coppernickel Cu/Ni 90/10 and 70/30, Admiralty brass, copper and carbon steel.
