Your Name:………………………………………………. Paper Type A SID:……………… ENME 636- Structural Analysis of Buried Steel Pipelines – Spring 2020 Midterm Exam June 2, 201 ... 9 1) [20 %] A new pipeline system is designed to carry non-sour natural gas from a compressor station 1 to 3 pressure vessels in a power plant fuel station. The pipeline route is given in the following figure. Calculate the maximum design pressure that the compressor can allowed to produce based on the following information:  Pipe outside diameter 10” (273.1 mm)  10” grade: Gr. 359 (SMYS = 359 MPa)  Purchased wall thickness: 10.31 mm  Pipe outside diameter 8” (219.1 mm)  8” grade: Gr. 359 (SMYS = 359 MPa)  Purchased wall thickness: 10.31 mm  Pipe outside diameter 6” (168.3 mm)  6” grade: Gr. 359 (SMYS = 359 MPa)  Purchased wall thickness: 10.31 mm  Corrosion allowance : 1.60 mm  Mill tolerance: 1.29 mm  Design temperature: -10°C to 40°C  Type of pipe: seamless  Design Factor: 0.8 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 2) [15 %] A cylindrical tensile test specimen of an unknown pipe material with length of 100 mm a diameter of 10 mm is subjected to a tensile load of 15,000 N. Since it is subjected to a tensile load, the diameter of specimen is reduced by 7 x 10-3 mm. Calculate the material’s Possion’s ratio considering a Young’s modulus of 100 GP [Show More]
