Rhokana welcomes you to a hub of innovative composite pipework, vessel, and storage tank repair technology for Southern Africa. We are Rhokana Engineering, the sole providers of Technowrap™ in Southern Africa.

Technowrap™ composite repair products are engineered repair solutions for pipework, vessel, and storage tank integrity and structural strengthening. They consist of fibers reinforced with an epoxy resin. The fiber reinforcements are either carbon or glass. Three types of epoxy resins are available, their selection is based on the overall design conditions and installation temperature of a repair. The repair systems are wet lay-up systems applied on site. The fiber reinforcement is woven into various architectures. The selection of fiber type and architecture is based on both performance or cost. As sole distributors in South Africa, Rhokana Engineering is part of the expanding network representing Walker Technical Resources Limited. Extremely affordable polyurethane, water activated pipe wrapping kits for low-pressure application and temporary fixes are also available.


Through research and development, Technowrap 2K™ has been developed to enable it to be applied in temperatures ranging from -103°F (-75°C) to 428°F (220°C). As a result this technology can be utilised in a variety of geometries and to suit the temperatures of all geographic locations.


For strengthening of tanks, vessels, roofs, floors beams, columns, support members, struts, bridge and jetty supports, accommodation modules, walkways, HVAC ducting, handrails ,signage.


Technowrap Splashzone™ has been designed for application of repairs on wet or submerged surfaces. Applications include caissons and risers suffering corrosion in the splash zone area or sub-sea pipelines. The ability to bend to wet substrates is due to our specially formulated epoxy-based resin. Technowrap Splashzone™ is designed for the repair of internal, external and through wall defects. Technowrap Splashzone™ can be used for pressures up to 250 barg/ 3625 psi and temperatures up to 60°C.


Technowrap PRS™ (pipeline repair system) is a composite repair system specifically for straight pipe sections. It was developed in response to demands from clients who required a product that provided a cost-effective method of returning externally corroded pipelines to their original pressure retention capability and structural design integrity.


Technowrap H.P. PRS™ is a high pressure pipeline repair system which has been designed for use on land. The system's intended application is for large diameters of pipe work, such as a 36 inch pipe operating at high pressures (greater than 50 bar). The uni-directional carbon based cloth is encased in our epoxy resin system


Technowrap Potable™ is a engineered, glass-based repair system specifically designed and certified for potable water applications and can be used on all pipe work components.

In the breadth of our long history as a supplier of Technowrap for Southern Africa, Rhokana Engineering has solved a wide variety of industrial challenges that range from the every day to the uniquely technical. Each has been approached equally with our engineering expertise in these fields; ensuring a perfectly tailored solution to each client's requirements.


Refinery in Mossel Bay, S Africa, Two 20 inch pipe couplings continually had leaking problems, creating underground seepage in the nearby town of Mossel Bay.


A refinery in Secunda South Africa experienced excessive internal erosion. Pin hole leaks had formed expelling ammonia into the atmosphere. Technowrap was asked to provide a solution.


The refinery in Durban South Africa, 36 inch Caustic and Mereox drum experienced excessive internal erosion. The requirement was to reintroduce integrity to the Drum enabling operations to continue safely until next shutdown. Pressure at 7 bar and temperature at around 50 °C.


A refinery in Durban South Africa experienced excessive corrosion under insulation. Pin hole leaks had formed and temporary clamps were used to contain the leaks in two areas.


Various Tanks at a refinery in South Africa had experienced mostly internal erosion over a number of years, the erosion had become severe on the roof outer perimeter and upper walls of the tanks.
