Tubes, Tube sheets, shells, Baffles and Fins of Heat Exchanger are made out of various custom required material & TEMA Standards like seamless or ERW tubes and shells in Copper Aluminum, Brass, mild steel, cupro Nickel, Aluminium brass and stainless steel, carbon steel, admiralty Brass materials are used. The end of the tubes are probably welded or expanded with grooved tube plates by digital tube expanding machines up to a pressure level of 1000 PS1 Pressure.
REX Heat Exchangers are carefully designed and tested from selection of raw materials as per specifications and the quality is tested with its own quality control departments. X-Ray Hydraulic, Pneumatic, penetration testing are the series of regular tests routinely adapted by REX to confirm and witness the quality as per standards. Also Third party inspection agency like DNB, TUB.BVQ, and NPCL are also arranged for Quality assurance.
