P (MPa), S (MPa), t+Ca (mm), s (MPa), Ca (mm), Pa (MPa). Horizontal test – Operation: 1.6133, 1.241, 161.1, 92.4, 0.13, 0.17, 9.07, 6.97, 0.00, 0.00, 28.6708, 16.4443. Cross-section view. Tube diameter = 25.4 mm; Length = 9,144 mm; Horizontal pitch = 62 mm; Vertical pitch = 53.69 mm. Tube-to-tubesheet joint. Weight of sliding header (with 750 mm of tube): W = 1,888.3 daN. St = 92.4 MPa; tt = 2.11 mm; dt = 25.4 mm; Nt = 240; S = 138 MPa; Et = 190,740 MPa; Lt = 9,144 mm. Friction factor: m = 0.3. Axial load due to thermal expansion: F = mW = 566.5 daN. Axial stress: st = F / (Nt × p × (dt – tt)). Value = 0.153 MPa. Allowable stress: For welded tubes: St,j = min(S, St(g/tt)); For expanded joints: St,j = 0.8 × min(S, St) (with 2 grooves). Maximum allowable differential thermal expansion: DLmax = (St,j – st) / Et × Lt = 3.536366 mm. My company, my address, my city. Design calculations, date: 2016-12-17.
