A Study on Analysis and Process Optimisation of Weld Joint in Pipes for Different Weld Positions
Divya S. N., Anand A.
Abstract: The important goal in the modern industries is to manufacture the products with lower cost and with high quality in short span of time. There are two main practical problems that engineers face in a manufacturing process. The first is to determine the values of process parameters that will yield the desired product quality (meet technical specifications) and the second is to maximize manufacturing system performance using the available resource. Welding operation is widely used in automotive, aircrafts and many other industries. Welding is an efficient method of making permanent joints between two or more metal parts. Liquids and gases are transported in pipelines and any chemically stable substance can be sent through a pipeline. Pipelines exist for the transport of crude and refined petroleum fuels such as oil, natural gas and bio fuels and other fluids including sewage, slurry and water. In pipe joining process strength of a pipe joint place a very important role. Because the internal and external forces and pressure will be very high in oil or gas pipe line transportation system. Piping element is defined as material required installing the piping system. Elements of piping include design specifications, materials, components, supports, fabrication, inspection and testing. Most of the operation in a process industry occurs at temperatures and pressure, which are different from normal atmospheric condition. These operations are often hazardous and do put the surroundings at risk. The job of the mechanical engineer is to confirm these risky operations within vessels and pipes, act as boundaries between these risky but necessary operations and the outer world While protecting the outer world from risk, these structure suffer stress and stress themselves. Any flaw or shortcoming in any of these aspects would mean that these structures would be unable to do their protector?s roll perfectly, and mishaps would occur. Mechanical designer have to make sure that the structure would guarantee reasonable safety for a reasonable period of time and not fail in spite of continuous or intermediate harsh condition faces by their design structure. Stress analysis is a subject, which is more talked about and less understood. The objective of pipe stress analysis is to ensure safety against failure of the piping System by verifying structural integrity against the loading condition both external and internal, expected to occur during the lifetime of the system in the plant.
