The Port Elizabeth branch of Oerlikon South Africa (Oesa) has supplied Algoa Oil with OP121TT flux for use in the rebuilding of oilfield equipment. This includes blow-up preventers and well-heads used on the ocean bed.
Algoa Oil chose OP121TT flux from Oesa after recommendations from other offshore companies which recognise the flux to be the industry standard.
OP121TT is a fluoride-basic, agglomerated flux. It is suitable for use on DC+ and AC up to 1 000 A on a single wire.
The flux is recommended for single or multiarc configurations for the welding of high-strength fine-grain steel and cryogenic steels. It is capable of providing these properties at high deposition rates using multiwire welding ensuring economic productivity. The product is also suitable for bulk welding techniques where introduction of metal powder additions to the weld pool further enhance productivity levels while maintaining excellent weld metal properties.
