An underwater oil and gas piping system is going to be established through South China Sea connecting Kerteh in Terengganu and Bintulu in Sarawak. The piping has an outside diameter of 400mm with wall thickness of 50mm. The material used for the piping is steel with E= 200 GPa, yield stress = 250 MPa, Poisson's ratio, v=0.3. The deepest sea is at 900m depth with the density of sea water is, p = 1050 kg/m3. What is the highest internal pressure that can be applied to pump the oil going through the piping if the maximum shear stress of the piping is allowed to be 120 MPa only. With the calculated value, sketch also the stresses profile along the thickness of the pipe.

Question
Transcribed Image Text:An underwater oil and gas piping system is going to be established through South China Sea
connecting Kerteh in Terengganu and Bintulu in Sarawak. The piping has an outside diameter
of 400mm with wall thickness of 50mm. The material used for the piping is steel with E= 200
GPa, yield stress = 250 MPa, Poisson's ratio, v=0.3. The deepest sea is at 900m depth with
the density of sea water is, p = 1050 kg/m3.
What is the highest internal pressure that can be applied to pump the oil going through the
piping if the maximum shear stress of the piping is allowed to be 120 MPa only. With the
calculated value, sketch also the stresses profile along the thickness of the pipe.
