In the process of transmission of oil and gas, installation of pipelines is usually buried in the ground. Reason pipeline should be buried is to avoid sabotage, accident risk, aesthetic factors, and when the cross residential, river and road. Therefore, the analysis should be performed on the burial depth of pipe of which is to analyze stress that occurred in the pipe under pressure due to land-based <br /> <br /> <br /> vertical ground ASME B31.4, ASME B31.8, and API RP 1102. <br /> <br /> <br /> The calculation and analysis using software CANDE 2007 is done at this final project to simplify the stresses analysis include deflection of underground buried pipes. The stresses is analyzed due to bending moment and thrust force, while the deflection is analyzed in the direction of <br /> <br /> <br /> lateral deflection and the vertical pipe. As a case study, the author analyzes the stress on the pipe section through which crossing at River Gerong. The size of the pipe is analyzed NPS 10 schedule 40. Analysis conducted at the KM 5 +250, KM 5 +430, and 5 +830 KM with varying depth of burial <br /> <br /> <br /> and pressure hydrostatic water river. <br /> <br /> <br /> From the results of the analysis of stresses and deflection is obtained that the position of all pipes that have analyzed the stress ratio from combination of bending and thrust < 1, so this is safe. Safe condition is also achieved from the vertical deflection < 2% based on the conditions allowed by the API RP 1102. Advice from the author is need to analysis stresses in longitudinal direction and stability analysis of ring due to soil and water pressure so that the results of the analysis more complete.
