Isometrics are documents showing a three-dimensional Isometric view of Pipeline. One can say that it is the final outcome of all Piping Engineering activities. Once the Final Isometrics are released it is used at the site and/ or at fabricators for erection or fabrication. Separate Isometrics will be there for every other line. Isometrics are prepared in A3 Size sheets and shows the profile of a line but the dimensions are not to scale. Isometrics are made in different stages. The number of stages may vary from consultancy to consultancy. In the very first stage, detailed dimensions won’t be there except locating a valve or showing upstream/downstream straight lengths for flow nozzles etc. These sketches will send to Stress groups and interdepartmental check for their inputs. In the final stage after receiving comments from other departments, the Isos will update and include detailed dimensions, Support mark-up, Bill Of Material and release with the signature of Piping Lead, St...
A Refinery Even though it is one of the most important aspects of Piping Design, There is no established code exists for Piping Layout. Piping Layout is all about the arrangement of Piping. Layout Preparation doesn’t deal with the ability of the piping system to handle fluid under given design condition, rather deals with the efficient and safe operation of the plant. A talented Piping Layout Engineer should possess good craftsmanship with great personal skills, creative imaginations etc. In preparing a good Layout. Depending upon the particular situation, the piping arrangement will vary from case to case. To ensure a well laid out piping, a logical approach is necessary with an intelligent and careful study by the Piping Engineer.Piping Plans are usually made area wise. Piping Plans: A piping Plan is usually made in 1:33 1/3 scale for process u...
