IMPROVE YOUR CRITICAL DRAWINGS Use best practices to foster consistency in P&IDs and PFDs

摘要

CRUCIAL DETAILS about chemical and hydrocarbon processing facilities reside in piping and instrumentation diagrams(P&IDs).These key dtawings contain a wealth of information beyond piping and insttumentation,including equipment,controls,configuration,safety and many other things.However,the look of P&IDs can differ markedly among industries,technology suppliers,engineering contractors,etc.In an effort to align the industry and generate value for its member companies,Process Industry Practices(PIP)has published a practice fot how to draw P&IDs.The consortium(see sidebar)was founded by 17 members in 1993 with the shared goal of reducing process facility costs through the development and implementation of common industry practices for design,procurement,construction and maintenance.PIP members now number at approximately 101 active members and 46 non-active members.Active-member-company volunteers have worked to harmonize and maintain over 500 published practices for the process-related indus-tries.Volunteers are split into function teams for specific practices,such as the one for P&IDs,PIC001.The P&ID function team is responsible for the P&ID practice and process-related questions.
