Job title: Piping Designer
Department: Engineering
Reports to: Design Engineering Manager
Location: [City], [office, branch or site]
About the role
A Piping Designer creates the piping layouts, 3D models and isometrics for a plant. They route pipes for process, safety and maintainability, place supports, and produce GA drawings and isometrics for fabrication and erection. The role sits in the design office and works in tools like PDMS, E3D or SP3D. A good Piping Designer routes clash free, follows the P&ID and stress needs, and delivers isometrics the fabrication shop can build without rework.
Key responsibilities
- Route piping in the 3D model to the P&ID, process and safety requirements.
- Prepare equipment layouts and piping GA drawings for each area.
- Generate isometrics, material takeoff and bills of material for fabrication.
- Place pipe supports and coordinate with the stress engineer.
- Run clash checks and resolve clashes with structural, electrical and equipment.
- Follow piping specifications, standards and the plot plan constraints for the area.
- Prepare tie in schedules and nozzle orientation drawings for erection.
- Review vendor equipment drawings for nozzle and piping interface information.
- Answer site queries and issue revised isometrics and layouts.
Requirements
- Diploma in mechanical engineering or piping design
- Training in PDMS, E3D or SP3D
- Knowledge of piping standards and specs
- 3 to 6 years in piping design

What does a Piping Designer do?
A Piping Designer creates piping layouts, 3D models and isometrics for a plant. They route pipes to the P&ID and safety needs, prepare GA drawings, place supports, run clash checks and generate isometrics and material takeoff for fabrication. Their job is a clash free, buildable piping design delivered on schedule.
What is the difference between a Piping Designer and a Piping Engineer?
A Piping Designer focuses on 3D modelling, layouts and isometrics. A Piping Engineer covers wider engineering: line sizing, material selection, stress, specifications and vendor coordination. The designer produces the model and drawings, while the engineer sets the requirements the model must meet. In smaller firms one person may do both.
What software does a Piping Designer use?
The main tools are AVEVA PDMS and E3D, and SmartPlant 3D for modelling, with AutoCAD for 2D and Navisworks for clash detection. Knowing at least one 3D plant design tool well, plus piping standards and isometric generation, is what most employers look for.
