1. Role Title

Piping Material Engineer

Reports To: Lead Piping Engineer / Engineering Manager

2. Summary

The Piping Material Engineer is responsible for the specification, selection, and standardization of piping materials, components, and specialty items to ensure safety, code compliance, and reliability for industrial projects. The role involves developing material classes, preparing material requisitions, reviewing vendor documents, and ensuring alignment with project standards, applicable codes, and client requirements. The Piping Material Engineer also collaborates closely with piping design, process, mechanical, procurement, inspection and construction teams to deliver fit‑for‑purpose solutions.

3. Key Responsibilities

Piping Material–Specific Responsibilities

• Develop, maintain, and update piping material specifications, and piping class sheets.
• Prepare pressure containment (wall thickness, branch reinforcement) and initial line sizing calculations.
• Provide input and assist in development of P&IDs.
• Prepare Bills of Material (BOM), material take‑offs, line and valve designation tables.
• Select appropriate piping materials based on process requirements, temperature, pressure, corrosion, and client standards.
• Prepare and review material requisitions (MRs), technical bid evaluations (TBEs), and purchase recommendations.
• Review and approve vendor drawings and documents for valves, fittings, specialty items, gaskets, studs, and flexible elements.
• Review and provide input to other discipline documentation to ensure alignment with piping interfaces.
• Ensure compliance with ASME, ASTM, API, MSS‑SP and other relevant international codes/standards.
• Coordinate with the process team to ensure correct material selection for corrosive, erosive, or hazardous services.
• Work with the piping design team to ensure material compatibility and alignment with routing and constructability.
• Develop valve datasheets, specialty item datasheets, and piping component catalogues.
• Resolve technical queries related to materials during engineering, procurement, fabrication, and construction phases.
• Support inspection and QA/QC teams with material compliance issues and vendor clarification.
• Support construction team with technical queries related to materials.
• Participate in HAZOP, model reviews, and discipline coordination workshops.

4. Qualifications and Experience

Essential

• B.Tech / B.E. in Mechanical Engineering or Metallurgy.
• 5-20 years of experience in piping material engineering in EPC or industrial project environments.
• Strong knowledge of ASME B31.3 / B31.1, ASME Section II, ASTM standards, API standards, and MSS specifications.
• Experience in developing piping classes, valve specifications, and specialty item datasheets.
• Familiarity with corrosive and high‑temperature service material selection.
• Ability to interpret P&IDs, piping isometrics, vendor datasheets, and material standards.
• Experience coordinating with procurement, inspection, and multidiscipline engineering teams.
• Strong communication, documentation, and technical writing skills.

Preferred

• Experience working on mining, chemical, oil & gas, or heavy industrial facilities.
• Familiarity with non-metalic piping materials.
• Knowledge of SAP/Smart Materials/SPMat or similar material management systems.
• Experience with valve sizing basics and specialty piping items (bellows, strainers, dampers).
• Experience in line sizing and/or hydraulic/pump sizing calculations.
• P&ID development and coordination.
• Exposure to material corrosion mechanisms and mitigation techniques.
• Experience supporting factory acceptance tests (FAT) and vendor quality surveillance.
