Pipe Manufacturing Process
- LSAW (Longitudinal Submerged Arc Welding)
- JCOE forming process
- DSAW (Double-sided Submerged Arc Welding)
The LSAW process offers superior weld quality, dimensional accuracy, and high pressure-bearing capacity, making it suitable for large-scale oil and gas transmission projects.
Project Overview
The ADNOC P5 Project is part of ADNOC’s long-term production expansion plan. CPP carried out the onshore facility upgrade works at the Bab and Buhasa oilfields to support UAE’s goal of increasing crude oil production capacity to 5 million barrels per day by 2027.
The project utilized API 5L X60MS PSL2 Annex H line pipes, compliant with NACE MR0175 sour service requirements, for crude oil transportation systems. The high-strength steel pipes provide excellent toughness, corrosion resistance, and reliable performance in challenging oilfield environments.
Project Challenges
Sour Service Environment
The Bab and Buhasa oilfields contain corrosive elements such as H₂S, requiring pipes with excellent resistance to Sulfide Stress Cracking (SSC) and Hydrogen-Induced Cracking (HIC).
Strict Material Requirements
API 5L X60MS PSL2 requires a balance of high strength, toughness, and corrosion resistance to meet demanding oil and gas service conditions.
High Weld Quality Requirements
The 508 mm LSAW pipes require precise welding control to ensure full penetration, consistent quality, and long-term pressure performance.
Multiple Standard Compliance
The pipes must meet not only API 5L PSL2 requirements but also Annex H and NACE MR0175 standards for sour service applications.
