PIPELINES

Fabrication, Installation & Components for Oil, Gas, and Industrial Infrastructure

END-TO-END PIPELINE SOLUTIONS

Sienna RM delivers comprehensive pipeline services through strategic partnerships with proven fabricators and installation teams. From initial design support through final commissioning, we provide the expertise and materials to keep your project on schedule and on budget.

Core Capabilities

🔧

Custom Fabrication

Precision-engineered pipeline spools, headers, and assemblies fabricated to ASME, API, and client specifications. We handle carbon steel, stainless, duplex, and specialty alloys.

⚙️

Field Installation

Experienced crews for pipeline tie-ins, welding, hydrostatic testing, and on-site commissioning. ASME-certified welders with current NDT qualifications.

🔬

NDT & Quality

Non-destructive testing including radiographic, ultrasonic, magnetic particle, and dye-penetrant examination. Full traceability and documentation packages.

Fabrication & Spooling

Our fabrication partners operate fully equipped shops capable of handling pipe sizes from ½" through 60" in diameter. All work is performed under strict QA/QC programs with ASME Section IX-qualified welders and comprehensive weld-mapping documentation.

Prefabricated spool pieces reduce on-site labor costs and compress project timelines. We coordinate shop drawings, material procurement, and fabrication sequencing to align with your construction schedule.

Installation & Commissioning

Field installation services include pipe laying, welding, bolt-up, and alignment for above-ground and below-ground piping systems. Our crews are experienced across refineries, petrochemical plants, power facilities, and midstream gathering systems.

  • Tie-in Management: Hot taps, line stops, and shutdowns planned and executed with zero-incident focus.
  • Hydrostatic Testing: Pressure testing per ASME B31.3, B31.4, and B31.8 with full documentation and certificate packages.
  • Commissioning Support: Pre-commissioning, line cleaning, and turnover procedures coordinated with operations.

Materials & Components

We source and supply a complete range of pipeline materials and components, leveraging established relationships with mills, foundries, and specialty manufacturers worldwide.

  • Pipe: Seamless, ERW, and LSAW in carbon steel, stainless steel, duplex, super duplex, and nickel alloys.
  • Fittings & Flanges: Butt-weld, socket-weld, and threaded fittings from 150# through 2500# ratings.
  • Valves: Gate, globe, check, ball, butterfly, and specialty valves from leading manufacturers.
  • Specialty Items: Expansion joints, strainers, steam traps, gaskets, and fasteners.
  • Coatings & Insulation: FBE, 3LPE, concrete weight coating, and thermal insulation systems.

Logistics & Project Support

Beyond fabrication and supply, we provide end-to-end logistics coordination — from mill release inspection and international freight forwarding to laydown yard management and just-in-time delivery to the construction site.
