Rehan Industries Africa CC was established in 2000, following a merger of Rehan Industries and African Heating (Mpumalanga). The directors of Rehan Industries Africa have a combined total of 40 years’ experience in the heat treatment technology field. Rehan Industries Africa CC work as consultants and was regularly subcontracted to various managing contractors (All Eskom projects), and also managed major contracts in South-Africa, as well on International levels.
Rehan Industries Africa CC is structured to provide tailor-made applications to meet client requirements by the continuously upgrading our equipment to ensure a professional heat treatment service, available for your convenience 24 hours a day and 7 days a week.
WHY HEAT TREATMENT?
Electrical resistance heating is one of the most cost-effective and efficient heat treatment methods available. Independent heating elements can be separately controlled, to allow an even spread and graduation of temperature across a workpiece. Using this method, even large pieces of steel can be held at controlled temperatures within very close for the required periods of time.
The availability of a range of different heating elements allows them to be adapted to almost any shape or joint configuration, while all temperatures are automatically controlled and recorded.
Upon completion of a heating cycle (Pre or Post weld heat treatment) temperature profile and history of the operation is retained for future record.
Electrical resistance heat treatment is recommended, when the following are essential to the work at hand:
- Evenly raising the temperature over the whole area to be heated by means of separately controlled independent-heating circuits is relatively simple.
- The heating circuits can be regulated either manually or automatically by auto controllers sensitive to signal from thermocouples fixed at strategic points over the heating area (workpiece)
- Very small and insignificant variations of temperatures
- Readily transportable equipment.
- Heating elements can be tailor-made to suit each workpiece in hand and re-used time and time again.
- Electrical resistance elements, powered by LOW VOLTAGE transformers and mains voltage distribution units, are operated by fully programmable control units and calibrated recorders.
