Leaking welded diaphragms of high pressure heat exchangers in hydrotreating and hydroprocessing service units are a serious problem for the petrochemical industry. The welded diaphragm is located just in front of the tube side cover plate and is highly stressed due to the combination of high pressure hoop stress and large compressive forces from the cover plate bolting.
The tube sheet is a plate or sheet that is perforated with holes for the insertion of pipes or tubes and designed to support the tubes on either end of the cylindrical shell. The shell extends beyond the tube sheets and is sealed on both ends to form the enclosed chamber that is covered by the heads. Vertical Shell and Tube Heat Exchanger United Heat Feb 23, 2018 · Vertical Shell and Tube Heat Exchanger is a heat exchanger that is derived from its parent Shell and Tube Heat Exchanger and it is most commonly all Industries which involves higher-pressure and Higher Temperature applications. A set of tubes is called the tube bundle and can be made up of several types of tubes:plain, longitudinally finned
The TORQ N SEAL® high pressure heat exchanger tube plug is a solid one piece plug that can be inserted to any depth of a leaking tube / tube sheet and installed by hand, providing unmatched flexibility and ease of use. The plug will expand approximately 35 mils (.035) to provide a positive mechanical contact seal and are rated up to 7,000 psi after being rigorously tested.
