Abstract

As the heart of every industry, the pipeline has an enormous role and influence, from simple roles such as water distribution to process piping. Almost a large percentage of factory performance in every industry depends heavily on pipeline size, pipeline equipment layout, and pipeline system in view of the possibility of work risks that may affect mechanism and operational safety. Pipe system is a combination of pipes and connectors such as elbow, tee, reducer, flange, valve and so on.But just like any other component in any industry, the pipeline system also often fails as an example is the frequent leakage in pipeline construction.Frequent leaks in pipes cause the need for stress analysis on pipe construction in order to save costs due to repeated pipeline replacements due to pipeline leakage. Leaks usually occur due to various factors such as pipe shape, pressure on the operating temperature pipe, and support. In the construction of pipe LV-201 one of the causes of the possibility of leakage in the pipe is the vibration that occurs in the construction of the pipe. To prevent the occurrence of leakage in the construction of the pipe due to vibration it is necessary to do additional support on the construction of the pipe so that the vibrations that occur can be muted. In its application the international standard code used to analyze pipe stress is ASME B31.3 Process Piping. This code is needed to analyze the stresses of regular loads such as internal and thermal loads and occasional loads eg earthquakes. The method in the research was first started by searching and studying references in the form of books, journals, and other scientific papers that discussed the pipe stress. This stress and displacement analysis is using with using software CAESAR II. The CAESAR II software is a software used specifically for analyzing the stresses and displacements that occur in pipe construction. To perform analysis with CAESAR II software required physical data of pipe in the form of pipe specification. Physical data can be obtained from the manual book from files PT Pupuk Sriwidjaja Palembang. Physical data in the form of drawings and dimensions of pipe construction can be obtained by conducting direct field survey. This physical data is required as input data in conducting stress analysis and displacement of pipeline construction in CAESAR II software. The stress and displacement analysis is performed by piping the construction of the pipe in a static state so that the stress in the analysis is due to the sustain load and the thermal load. The stress generated by the dynamic load is negligible so that the stress analysis and displacement of the pipe construction due to the occasional load are not included in the analysis. Analysis begins with made a model of pipe construction LV-201. The input data in CAESAR II is pipe length, pipe size, Schedule, material, corrosion allowance, pipe density, fluid density, temperature, pressure, insul thickness, insul density. Other input data can be input in accordance with the needs and cases in the pipeline. The node in the pipe construction model is determined by a scale of 10 at each node in the pipe construction. The analysis is done after passing the Check error stage. The results of analysis in the form table of bending stress, torsion stress, allowable stress, axial stress, hoop stress and displacement on each node. Maximum bending stress, maximum torque stress, maximum allowable stress, maximum axial stress, maximum hoop stress can be seen at the beginning of the analysis result table. The results of the analysis are differentiated by the stresses due to the sustain and thermal load. The presentation of the analysis results is loaded in the form of a stress graph and displacement graph on each node of the pipe construction model. The conclusions were drawn by comparing the results of maximum code stress in pipeline construction with allowable stress, with expected results of the maximum code stress occurring in pipeline construction still under the allowable stress of the material
