What We Do
Our Services
25+ service lines covering every aspect of industrial valve maintenance, testing, inspection, engineering, and field operations — all from a single, certified partner.
Valve Services
Valve Services
Testing, repair, overhaul, and certification for all valve types — from safety valves to control valves and manual valves.
Safety Valve Testing, Repair & Certification
Full PSV/PRV lifecycle: pop-test, overhaul, re-certification, and LESER OEM repair as the only LARC in Tunisia.
Control Valve Repair & Diagnostics
Valve positioner calibration, trim replacement, actuator overhaul, and partial stroke testing to restore full control loop performance.
Manual Valve Testing & Repair
Gate, globe, ball, butterfly, and check valves — pressure testing, seat repair, packing replacement, and full overhaul.
Actuator Repair & Overhaul
Pneumatic, electric, and hydraulic actuator repair, reconditioning, and performance testing for all major brands.
Repair by Exchange
Swap your failed valve for a certified reconditioned unit from our stock — zero waiting time for critical spares.
Field Services
Field Services
On-site repair, machining, testing, and maintenance brought to your plant by our mobile workshops.
Field Services: Repair, Machining & In-Situ Testing
Two mobile workshops bring our certified repair and testing capabilities directly to your plant — minimising downtime and eliminating transport risk.
Bolting & Torquing
Controlled bolting with hydraulic torque tools and tensioners to engineered load specifications — preventing leaks and gasket failures.
Motor & Pump Alignment
Precision laser shaft alignment for rotating equipment — pumps, compressors, turbines, and gearboxes.
Inspection & Testing
Inspection & Testing
NDT, API inspection, hydrostatic testing, helium leak testing, and metallurgical analysis.
Non-Destructive Testing (NDT)
UT, MT, PT, RT, VT and PAUT inspection services for welds, pressure vessels, piping, and structural components.
Instrumentation & Calibration
Traceable calibration of pressure, temperature, flow, and level instruments — on-site or in our accredited calibration lab.
Water & Oil Pressure Testing (Hydrostatic Testing)
High-pressure water and oil hydrostatic testing, alongside pneumatic testing, for vessels, piping, valves, and fabricated assemblies — fully documented.
Helium Leak Testing
Ultra-sensitive helium mass spectrometer leak detection for critical sealing applications where conventional pressure tests are insufficient.
API Inspection Services
Risk-Based Inspection (RBI), API 510 vessel inspection, API 570 piping inspection, and API 653 storage tank inspection.
Pipeline Testing & Integrity
Hydrotest, intelligent pigging co-ordination, corrosion monitoring, and fitness-for-service assessments for oil and gas pipelines.
Metallurgical Testing
Material analysis, hardness testing, PMI, microstructural examination, and failure analysis for industrial components.
Engineering & Fabrication
Engineering & Fabrication
ASME welding, skid fabrication, reverse engineering, CNC machining, and shutdown management.
Reverse Engineering & CNC Machining
Custom-machined replacement parts for obsolete or unavailable components — using CMM measurement, 3D modelling, and precision CNC.
Shutdown Management & Commissioning
Full turnaround planning, scope execution, and commissioning support — on time and within budget.
ASME Code Welding
Certified ASME Section VIII and Section IX welding for pressure vessel repairs, piping, and fabricated assemblies.
Engineering & Commissioning
Process engineering support, P&ID review, relief system design, equipment selection, and pre-commissioning / commissioning for new and revamp projects.
Modular Skid Fabrication
Design, fabricate, and test complete process skids — chemical injection, manifold, metering, purge/blanketing, and utility skids.
Purging, Inerting & Blanketing
Nitrogen purging, oxygen displacement, and continuous blanketing services for storage tanks, vessels, pipelines, and process systems.
Heat Exchanger Repair
Tube plugging, tube bundle replacement, tubesheet repair, and hydrotest for shell-and-tube, air-cooled, and plate heat exchangers.
Boiler Retubing & Repair
Fire-tube and water-tube boiler inspection, retubing, repair, and certification to ASME Section I and local regulatory standards.
Training
Training
Practical, hands-on technical training for your engineers, technicians, and operators.
