Common Questions
Pipeline & Flowline FAQs
What is the difference between a pipeline and a flowline?
A pipeline typically moves product over longer, cross-country distances; a flowline is the shorter, in-field piping that gathers product from wellheads to a processing or storage point. UCES delivers both.
Which codes govern pipeline welding and installation in the UAE?
API 1104 governs pipeline welding, with ASME B31.3, B31.4 and B31.8 covering process, liquid and gas piping design, alongside ADNOC’s own HSE-MS and technical specifications on ADNOC-linked projects.
Is UCES Middle East ADNOC-approved for pipeline and flowline work?
Yes. UCES Middle East is an ADNOC Approved Supplier and ICV Certified, operating under an ISO 9001:2015 quality management system.
Can you tie in to an existing, live pipeline network?
Yes — tie-in, fabrication and hook-up works are coordinated with the operator to minimize disruption to systems already in service.
What equipment do you mobilize for a pipeline project?
Pipe layers, welding machines, side booms and testing units, supported by experienced engineers, qualified welders and skilled technicians.
