The Pipe Drawing Checker uses practical knowledge of pipe fabrication, welding, materials, non-destructive examination, heat treatment, coating requirements, and material traceability to evaluate drawings and identify issues that could result in shop delays, rework, or field fit-up problems. This position reviews drawings against isometrics, bills of material, line information, weld requirements, material specifications, and established pipe fabrication practices to identify errors, omissions, discrepancies, and potential constructability issues before fabrication.
