C~ <br />APPENDIX H <br />• <br />Pressurisation Stress <br />The static stress on the pipeline due to the internal pressurization <br />is calculated using the equation <br />Stress PD <br />2h <br />where P ~ narc~l operating pressure, <br />D ~ pipeline diameter, sad <br />h ~ pipeline wall thiclmesa. <br />The values of "P", "D", and "h" for the pipelines are given in Appendix A and <br />yield the following: <br />Raton Cis Transmission CboQamr 11.000 psi <br />• <br />2-8 <br />
