§ 01 · Scope of services
§ 01.1Steam systems
Planned maintenance, breakdown response and repair of fire-tube and water-tube boilers used in industrial, hospital and food processing plants.
§ 01.2Pressure vessels
Inspection, recertification and repair of pressure vessels under OHS Reg 17. From small autoclaves to industrial receivers and steam drums.
§ 01.3Valves
A fully equipped valve workshop in Roodepoort handling steam safety, pressure-reducing, control, isolation and custom valves, local and imported.
§ 01.4Process & HVAC support
Servicing the equipment downstream of the boiler that depends on clean, regulated steam, the equipment hospitals and food plants run every day.
§ 02 · The workshop
Most of our work happens on a client's plant. The work that comes back to base, refurbishment, lapping, pressure-testing, sandblasting, has a dedicated home in Maraisburg, Roodepoort.
§ 03 · Inspection & testing
Detection of weld and material defects in pressure-containing equipment without taking the asset out of service. Performed in collaboration with certified AIA bodies where required.
Surface and near-surface flaw detection on ferromagnetic components, boiler shells, manhole rings, vessel headers, using wet-fluorescent and dry-powder methods.
Ultrasonic wall-thickness measurement on shells, heads and piping to track corrosion allowance and confirm fitness for continued service before recertification.
Functional, set-pressure and seat-tightness testing of safety, control and isolation valves, with traceable certificates produced from the workshop test bench.
Removal, inspection, lapping, reassembly and recalibration of steam safety valves to the original set pressure, the line of defence between an over-pressurised vessel and your people.
§ 04 · Valve supply & refurbishment
Where possible, we refurbish the valve you have. Where not, we supply a new or imported equivalent, sourced through our import / export agency for steam valves and pressure equipment.

§ 05 · Statutory framework
The Occupational Health and Safety Act and Regulation 17 (Vessels Under Pressure) set the rhythm: 12 / 24 / 36-month windows, AIA witness, compliant documentation. We don't reinterpret it. We just deliver to it.
