P&IDs, Pipe Sizing, Piping Layouts, and Isometrics

About the Course

Piping systems are critical components of industrial facilities, directly influencing operational safety, process reliability, maintainability, and construction efficiency. Increasing project complexity, tighter operational requirements, and multidisciplinary coordination demands require engineers and designers to apply structured approaches to piping design and documentation. Effective interpretation of P&IDs, accurate pipe sizing, efficient piping layouts, and fabrication-ready isometric drawings are essential to support safe and cost-effective plant operations. The integration of design standards, process requirements, hydraulic calculations, and layout optimisation is necessary to minimise pressure losses, operational constraints, and construction conflicts. In many projects, poor piping arrangements, incorrect sizing calculations, inconsistent drawing practices, and inadequate layout coordination contribute to operational inefficiencies, rework, safety risks, and increased project costs.

This 5-day P&IDs, Pipe Sizing, Piping Layouts, and Isometrics training course provides a structured approach to piping engineering design and documentation across industrial facilities. It integrates practical methods in P&ID interpretation, hydraulic sizing calculations, piping layout development, stress considerations, and isometric preparation aligned with ASME piping codes and industry engineering practices. Emphasis is placed on layout optimisation, pressure drop control, constructability, digital coordination, and fabrication accuracy. Delegates will strengthen their ability to interpret engineering drawings, evaluate piping configurations, and prepare accurate piping deliverables for design and construction activities. It equips delegates with structured frameworks and practical tools to improve piping system reliability, design coordination, and project execution performance.

Core Objectives

By the end of the training course, delegates will be able to:

• Interpret P&IDs, process flow information, and piping symbols
