As a preferred supplier for EPC contractors, energy operators, and mechanical contractors, Mcneil Alloys ensures complete documentation, heat traceability, material test certification, and project-compliant delivery.

Understanding the Importance of Dolphin Approval

Dolphin approval is not a simple endorsement—it represents a comprehensive validation of material integrity, chemical composition, mechanical strength, manufacturing processes, testing methodologies, and traceability records. This approval ensures that the pipes can safely withstand:

• High-pressure natural gas transport
• Marine and offshore corrosion
• Continuous operational temperatures
• Sour service and corrosive environments
• Long pipeline distances and pressure fluctuations

By achieving Dolphin compliance, each pipe becomes suitable for critical operations where failure is not an option.

Applications of Dolphin Approved Pipes in Oil & Gas Infrastructure

The Dolphin Gas Project forms a major part of the GCC’s energy ecosystem, with operations spanning subsea extraction, gas processing, condensate handling, and long-distance transmission. Our Dolphin Approved Pipes serve a wide range of applications including:

Offshore Platforms & Subsea Pipelines : These pipes handle harsh marine environments, high salinity, and constant exposure to pressure variations. Dolphin Approved Pipes offer the corrosion resistance and toughness needed for offshore structures.

Onshore Gas Processing & Compression Units : From separation units to dehydration columns and gas compression trains, our pipes offer stable performance under high temperature, vibration, and mechanical stress.

Cross-Border Pipeline Networks : Pipes approved under Dolphin standards ensure safe, loss-free transmission of natural gas from Qatar’s offshore North Field to receiving facilities in the UAE and Oman.

Receiving Terminals & Booster Stations : Dolphin Approved Pipes support final distribution, pressure adjustment, and condensate management within terminal facilities.
