This paper discussed about evaluation stress on gas pipeline. A pipeline transports LPG (Liquefied Petroleum Gas) from jetty to storage tank area along 1200 meters. The pipeline has nominal pipe size (NPS) 10 inches and buried in areas with high population levels (areas with high consequences). At KP 800 meter the segment of pipeline has road crossing conditions, where vehicles such as heavy vehicles pass across above. Pipeline has operated during about 8 years, it necessary study to evaluate the integrity or strength. One of the methods to evaluate buried and road crossing pipelines is determining stress occurs. Stress analysis for pipeline road crossing is evaluated using code API RP 1102 (Pipelines Crossing Railroads and Highway). Based on these standards, the pipeline road crossing is evaluated by stress components such as (a) Circumferential Stress, (b) Longitudinal Stress, (c) Radial Stress. The calculation will be analysed using spreadsheet modelling. Based on the stress analysis in existing operational condition, the segment in KP 800 is Acceptable according Standard API 1102. All parameters show acceptable, furthermore the pipeline is concluded in satisfactory condition.
