Video inspection
Video inspection equipment verifies system cleanliness. Lighted insertion tubes capture video or still images deep within equipment, pipelines and dark spaces; units cover ¾”–2” and 4”–60” pipelines, with powered robotic crawlers for vertical pipes.
- Reduces or eliminates manned entry
- Enables inspection of pipes from ¾” to 60”
- Up to 200 metre reach
- Visualises deposits, corrosion and failed mechanical components
Chemical cleaning
Removes scales, deposits and other unwanted materials from process equipment, piping and wetted or heated surfaces by chemical or solvent action, including nanoemulsion cleaning and deposit softening, dissolution or modification of physical properties.
- Deposit removal
- Increased plant efficiency and heat transfer
- Reduced operating costs
- Improved produced product
Flange management
Tagging systems and bolting software manage the integrity of bolted joints in pressurised systems through a best-practice control process for recording and gathering relevant data with multi-part flange tags, creating an auditable historical trail. Bolt-load software recommends tightening methods, tooling, torque and tension; two standalone programmes conform to ANSI and API standards without a server link.
Equipment includes manual bolting tools, tensioning tools, torquing tools, hydraulic accessories and pumps, pipe-flange spreaders and ultrasonic flange testers.
Pressure & leak testing
Leak testing identifies defects that affect component or process-system integrity. Regional equipment fleets include N2 equipment, tanks, high-pressure testing pumps, instrumentation and accessories.
- Protects personnel health, equipment safety and the environment
- Nitrogen / helium leak detection
- Pneumatic strength testing
- Hydrostatic pressure-drop and gas-decay testing
- Soapy-bubble and vacuum methods
Retro jetting & hot-oil flushing
Hydro or retro jetting uses 5,000–17,000 PSI high-pressure water and line-mole nozzles to move inside pipework, dislodge and flush mud, scale and construction debris, and sweep loose debris with sufficient water flow. It covers pipeline sizes 2”–44” and supports foulant and coating removal using hand lancing, line moles, heat-exchanger bundle cleaning and a water knife. Equipment cleaned includes boilers, heat exchangers, feed-water, cooling-water, fire-water, lube-oil, hydraulic, condenser, process-piping and reactor systems.
Hot-oil flushing removes contaminants and impurities from control, lubricating and hydraulic fluids before commissioning or after shutdown maintenance. The initial clean follows exacting cleanliness standards; applications include lube oil, seal oil, control hydraulics, subsea controls, umbilicals and regular servicing of hydraulic systems. Benefits include trouble-free start-up, reduced unplanned downtime, longer bearing life and continuous operations.
