PIPELINE WORKS SERVICES

Oil & Gas & HVAC Systems – Complete High-Side & Low-Side Execution

We deliver complete, end-to-end pipeline execution services for Oil & Gas, Process Plants, Utilities, and HVAC systems, covering high-pressure (High-Side) and low-pressure (Low-Side) piping networks.

Our scope spans from engineering review and material control to fabrication, erection, testing, commissioning, and final handover, ensuring safe, leak-free, and code-compliant pipeline systems.

HIGH-SIDE PIPELINE WORKS

(Process & Pressurized Systems)

High-Side pipeline works involve pressurized, process-critical lines where weld integrity, material compliance, and testing accuracy are essential for safety and continuous operation.

Scope of High-Side Works

  • Carbon Steel, Alloy Steel & Stainless Steel pipelines
  • Process piping for oil, gas, chemicals & utilities
  • Valve installation (Gate, Globe, Ball, Check, Control Valves)
  • Nozzle connections & equipment tie-ins
  • Stress-sensitive & vibration-prone line installation

Key Activities

  • Review of P&ID, Isometrics & Line Lists
  • Material verification & traceability (MTC control)
  • Pipe cutting, beveling & fit-up
  • Welding (GTAW / SMAW / SAW)
  • Weld joint identification & traceability
  • NDT coordination (VT, RT, UT, MPI, PAUT as applicable)
  • Hydrostatic / Pneumatic Testing
  • Drying, flushing & preservation
  • Final reinstatement & commissioning support

LOW-SIDE PIPELINE WORKS

(Utility & HVAC Systems)

Low-Side works include utility and HVAC pipelines operating at low to moderate pressures, where flow efficiency, alignment, cleanliness, and insulation quality are critical.
