 The first pipeline would later be extended to deliver petroleum products to Klerksdorp, Potchefstroom and Langlaagte in mining towns near to Johannesburg.Though the first pipeline was not entirely successful, the SAR&H decided to build a larger pipeline and also meet the strategy of the government, to stockpile oil in mines as means to protect against a proposed oil boycott by the international community opposed to the country's Apartheid policies.This pipeline came into commission in 1969, with an eighteen-inch diameter, costing R50 million (1970) and routed from Durban over the Drakensberg to Sasolburg and its new Natref refinery with pipelines to Kendal and Ogies for storage of crude oil in old coal mines.
