Valve & Actuation Turnaround, Overhaul & In-Situ Repair Services
Rapid-response planned outage and emergency turnaround services. We deploy containerized mobile machine shops, certified API 598 hydrostatic test benches, and cryogenic leak detection trailers directly to customer battery limits to overhaul, lap, and re-certify critical-path valves within plant outage windows.
Six-Stage Turnaround Protocol
Structured execution aligned with API 598, ASME PCC-2, and ISO 15848-1 leak detection standards for zero uncontained fugitive emissions.
Pre-Outage Walkdown & Asset Tagging
Site baseline ultrasonic leak inspection, acoustic emissions profiling under live line pressure, and preliminary Bill of Materials (BOM) staging.
Safe De-Isolation & Flange Machining
In-situ flange refacing, RTJ phonographic groove re-machining, stud tensioning release, and verified mechanical isolation lockout.
Containerized Disassembly & NDT
Transfer to mobile trailer shop, metrological optical dimensioning, ultrasonic thickness mapping, and liquid dye penetrant inspection of seating faces.
Precision Lapping & Trim Rebuild
Stellite Gr. 6 weld overlay restoring, matched orbital lapping, live-loaded gland packing replacement, and new certified OEM laminated seal rings.
Hydrostatic & Gas Test (API 598)
Hydrostatic shell test up to 450 bar, high-pressure nitrogen back-seat testing, and ISO 5208 Rate A zero-bubble pneumatic seat leakage verification.
Re-Installation & Digital Passport
Cold commissioning, torque-pattern signoff, actuator calibration, and QR-tagged digital MTR/test charts affixed directly to each valve neck.
Service & Outage Scope Dispatch Request
Submit technical site parameters directly into VALVEX Field Operations. Responses, work-pack estimates, and container dispatch schedules are returned within 24 business hours.
Fast-Track OEM Overhaul Kits Lookup
Input existing valve serial numbers or standard kit codes to verify real-time depot stock across our Edmonton, Houston, and Rotterdam logistics warehouses for emergency courier dispatch.
Mobile Container Fleet Equipment Specifications
Hydrostatic & Pneumatic Test Bench
Integrated inside 40-foot climate-controlled ISO container trailers. High-capacity clamping system for flange-mounted and weld-end valves up to DN1200.
Internal-Mount Flange Facer
Pneumatic drive heavy-duty facing machine for restoring raised face (RF), flat face (FF), and ring type joint (RTJ) grooves directly in the pipeline run.
Conical Orbital Seat Grinder
Proprietary computer-guided orbital seat reconditioning tooling specifically calibrated for non-concentric triple-offset valve geometries.
Certified Overhaul Accreditations & Safety Rating
Every turnaround team operates under stringent international valve manufacturing QA and rigorous plant-site safety management systems.
