Frequently Asked Questions – Shell Specification Flanges

What are Shell specification flanges? +
Shell specification flanges are flanges manufactured in accordance with technical requirements, material standards, and inspection procedures referenced in Shell project specifications and EPC datasheets. These flanges are produced to meet defined pressure, temperature, and service conditions rather than generic industrial use.
Are Shell specification flanges officially approved by Shell? +
Flanges supplied by Mcneil Alloys are manufactured to comply with Shell-referenced project specifications. Final approval and acceptance are typically carried out by the EPC contractor, third-party inspection agency, and the project owner during the inspection and documentation review process.
Which materials are commonly used for Shell flanges in UAE projects? +
Material selection depends on service conditions such as pressure, temperature, and fluid composition. Common materials include carbon steel, alloy steel, stainless steel, duplex and super duplex grades, and nickel alloys for sour service, offshore, and high-corrosion environments.
What documentation do EPC contractors require for Shell specification flanges? +
Typical documentation includes EN 10204 3.1 or 3.2 mill test certificates, PMI reports, non-destructive testing results, mechanical test reports, heat treatment records, dimensional inspection reports, and full material traceability. These documents support inspection and acceptance during Shell-referenced projects.
