Plant Piping Shutdown & Turnaround Services in Qatar
Industrial plant turnarounds (TAR) and planned shutdowns are high-stakes events where hundreds of critical piping modifications, tie-ins, and inspection tasks must be completed within tight, around-the-clock schedules. Qatar Piping provides turnkey shutdown execution teams, project managers, certified welders, riggers, and mechanical fitters to execute complex turnaround scopes on schedule and with zero lost-time incidents.

Execution Methodology
Pre-shutdown planning (T-12 to T-1 month): 3D scanning, spool prefabrication, hydrotesting, staging of materials.
Blind-to-blind isolation, positive mechanical blinding, and verification of zero energy state.
Cold-cutting of tie-in locations immediately upon unit handover and atmospheric clearance.
Round-the-clock 2-shift execution of critical-path field welds and flange bolting.
Real-time NDT clearance and hydrotesting / pneumatic testing.
De-blinding, nitrogen purging, and support during plant startup.
Quality Control & Traceability
Flange management tagging system (four-part tear-off tags tracking torque and inspection), golden weld register, 100% MTC and WPS verification, daily punch list clearing.
Inspection & Testing Regimes
On-site mobile NDT (PAUT / RT / PT), hydrostatic testing with rapid fill/drain systems, helium leak testing.
