...Mohamed Fayas Saffiudeen; Dinu Thomas Thekkuden; Abdel-Hamid Ismail Mourad; Fasil T. Mohammed; Abdullah Syed; Khalid Abdulrahman Al-Sayed; Yassir A. Alamri; Mohammad N. Al Qahtani Flawless tube and tubesheet joints are necessary for shell and tube heat exchanger with high leakproof ability...

...Guodong Zhu; Caifu Qian; Mingde Xue Strength calculation for tubesheets in floating-head heat exchangers (FHXs) in current standards is based on analytical theory which assumes that the two tubesheets are symmetrical with same thickness, same material. This assumption results in a design...

... expansion and also functions as a pressure retaining part. Design of expansion joints is usually based on trial and error method in which initial geometry must be assumed, and accordingly maximum stresses and spring rate are be calculated. Inadequate selection of geometry leads to higher tubesheet...

...Masanori Ando; Hideki Takasho; Nobuchika Kawasaki; Naoto Kasahara Basically, the thermal stress mechanism of a tubesheet is hoop stress inducement caused by interaction between the perforated and surrounding regions. When a thermal transient occurs, the temperature of the perforated region...
