What We Do

Heat Exchanger & Tube Bundle Cleaning

Priority: Highest demand — core shutdown service
High-pressure and ultra-high-pressure jetting of heat exchanger tubes and bundles to remove scale, polymer build-up, coke, and process deposits. Restores heat transfer efficiency and is a core requirement of every planned shutdown in petrochemical and power generation plants. Includes internal tube lancing and external bundle blasting, with automated/rigid lancing options for consistent results.

Tank, Vessel & Silo Cleaning

Priority: High value — confined space specialist work
HP and UHP jetting of storage tanks, process vessels, reactors, and silos to remove sludge, polymerised product, scale, and corrosion deposits. Remote-operated tank cleaning heads and robotic systems reduce or eliminate confined space entry — a major safety and cost advantage for clients.

Pipeline, Drain & Sewer Jetting

Priority: Recurring — high-frequency maintenance demand
Rotating-nozzle jetting of process pipelines, effluent lines, drains, culverts, and sewer systems to clear blockages, scale, sludge, and concrete or chemical residues. Self-propelled nozzle units handle long pipe runs. A recurring, plant-wide maintenance requirement and a natural bridge to SJA's Industrial Plumbing offering.
Relevant to: All target clients — every industrial site operates drainage, effluent, and process pipework requiring routine jetting

Surface Preparation & Coating Removal

Priority: Project-driven — supports maintenance & capital projects
UHP water jetting to remove paint, rust, scale, and failed coatings, preparing steel and concrete surfaces to recognised cleanliness standards (NACE/SSPC WJ-1 to WJ-4) ahead of recoating or inspection. A dust-free, abrasive-free alternative to grit blasting — significant in environments where spark and dust control matter.

Boiler & Furnace Descaling

Priority: Shutdown-critical — power & process industry staple
High-pressure jetting of boiler tubes, furnace walls, economisers, and ash-handling systems to remove slag, clinker, ash build-up, and scale. Performed during planned outages to restore thermal efficiency and meet inspection requirements.
Directly relevant to: Eskom power stations, Sappi recovery boilers, Sasol steam plant

Hydrodemolition & Cold Cutting

Priority: Specialist differentiator — high margin, low competition
UHP water jetting for selective concrete removal (hydrodemolition) and cold cutting of steel in no-spark/no-fire zones. Critical in petrochemical environments where hot work is restricted or prohibited. A specialist capability that few regional competitors offer.
