Refinery Engineering Design & Documentation Services
Engineering support for refinery brownfield modifications, shutdowns, turnarounds and pipe rack design in Saudi Arabia — piping, structural, vessel and documentation services in KSA.
SLETEC Engineering supports refinery operators and EPC contractors with brownfield modification engineering, process piping design and isometrics per ASME B31.3 and API 570, shutdown and turnaround engineering, pipe rack structural design and as-built drawing updates. Our deliverables are produced to the standards required by Saudi Aramco, API codes and refinery project specifications.
Refinery piping engineering involves specific technical challenges — high-temperature and high-pressure service, ASME B31.3 Category M fluid designation, fitness-for-service assessment for ageing equipment, and strict documentation requirements for in-service modification. SLETEC is experienced with these requirements across crude distillation, hydrotreating, reforming and utility units.
We serve refinery operators, maintenance contractors and engineering consultants at Ras Tanura, Jubail, Yanbu, Riyadh and other Saudi Aramco and independent refinery locations across the Kingdom of Saudi Arabia.
Engineering documentation prepared with reference to API, ASME, AISC, AWS, ISO, Saudi Aramco, SABIC and client project specifications where applicable.

Frequently Asked Questions
What refinery engineering services does SLETEC provide?
SLETEC provides refinery engineering services including brownfield modification engineering, piping design and isometrics per ASME B31.3 and API 570, shutdown and turnaround engineering support, pipe rack structural design, as-built drawing updates, pressure vessel modification, API 653 tank repair engineering and NMR/MDR documentation for refineries in Saudi Arabia.
Does SLETEC support refinery shutdowns and turnarounds?
Yes. SLETEC provides shutdown and turnaround engineering support for refineries including method statements, modification drawings, temporary support calculations, piping tie-in packages and as-built documentation. We produce deliverables to tight shutdown schedules for refineries operated by Saudi Aramco and independent refinery operators in Saudi Arabia.
Can SLETEC produce brownfield modification drawings for in-service refineries?
Yes. Brownfield engineering is a core capability at SLETEC. We produce modification piping drawings, structural modification packages, tie-in detail drawings and as-built updates for in-service refinery units — working from field survey data, P&IDs and existing drawing sets. Our deliverables meet Saudi Aramco, API and client project standard requirements.
Is SLETEC familiar with API 570 piping requirements?
Yes. SLETEC produces piping engineering documentation with awareness of API 570 in-service piping inspection requirements — including piping modification drawings that accommodate inspection access, minimum thickness requirements and piping circuit documentation. We work with plant integrity teams to ensure modification drawings support API 570 compliance.
