Services
Pipe Supports
Design, inspection, and repair of engineered pipe supports and restraints for industrial facilities. Our ASME-certified engineers ensure compliance with safety codes while optimizing system longevity. Services include snubber refurbishment, material supply, and outage planning for power and petrochemical plants.
Nondestructive Testing
Advanced testing techniques including ultrasonic, radiography, and phased array ultrasonics for critical infrastructure. Our Level III-certified technicians identify material degradation in piping, pressure vessels, and structural components across power, marine, and manufacturing sectors.
UAV Inspections
FAA-licensed UAV inspections for confined spaces and elevated structures. Using collision-tolerant drones with HD and thermal imaging, we assess boiler internals, stacks, and cooling towers without scaffolding, reducing risk and downtime.
Mechanical Welding
ABS-certified welding and fabrication for industrial piping systems. Our NBIC R-stamp holders perform repairs and installations on stainless steel, carbon steel, and exotic alloys, with on-site welder training programs for client teams.
Condition Assessment
Comprehensive evaluations of high-energy piping systems using hot/cold inspections and isometric analysis. We develop repair plans and maintenance schedules to mitigate flow-accelerated corrosion and creep failures in power plant infrastructure.
