Transnet pipelines, formerly known
as Petronet, the custodian of the country’s strategic pipeline assets,
is currently servicing two key industries (fuel and gas) by transporting
petroleum and gas products over varying distances. Our business, having
been established in 1965, is integral to the well-being of the South
The business handles an annual average throughput
of some 16 billion litres of liquid fuel and more than 450 million
cubic metres of gases. The liquid products include crude oil as well as
diesel, leaded and unleaded petrol and aviation turbine fuels.
The Pipeline Network
liquid fuels network traverses the provinces of KwaZulu-Natal, Free
State, Gauteng, North West and Mpumalanga. The intake stations are the
two Durban refineries - the crude refinery at Coalbrook (Natref) and the
Sasol 2 and Sasol 3 synfuel plants at Secunda. The network includes a
tank farm, at Tarlton, with a capacity of 30 million litres which is
used mainly for storage and the distribution of liquid fuels into
The gas pipeline, a converted line previously used for
liquids, runs from Secuda to Durban via Empangeni. It has take-off
points at Newcastle and Richards Bay as well as along the route between
Empangeni and Durban.
All Transnet pipelines' pipelines conform to
ASME B31.4, an American code of practice, with their diameters
designated in inches from six inches (nominally 150 mm) to 20 inches
(nominally 508 mm). Pressure in the pipeline network is monitored on a
24 hour-a-day, 365 days-a-year basis at the control centre at Transnet
pipelines' Durban head office.
Transnet pipelines' staff
complement of some 600 is deployed across the pipeline network with the
business itself being geographically decentralised. The regional offices
in Bedfordview are in the north of Johannesburg, housing the main
support functions including marketing, finance, human resources,
technical, projects and information systems, with a second branch
located in Pinetown.
pipelines' customers are all South Africa's major fuel companies
namely; BP, Caltex, Engen, Exel, Sasol Oil, Sasol Gas, Tepco, Shell and
Total. Many of these organisations are empowerment companies,
representing new players in the market.
Market SharesTransnet pipelines' network transports 100% of South Africa's bulk petroleum products.
The Natref inland refinery receives all of its crude oil requirements from Transnet pipelines' pipelines.
pipelines continually monitors the integrity of its pipeline network.
Internal inspection tools, known as Intelligent Pigs, are valuable
devices for this work. They make use of the magnetic stray flux
principle to determine and record possible areas of metal loss from
corrosion or any other cause. The results of the most recent Intelligent
Pig survey of the network indicate that the pipelines, which are
methodically protected against electrolytic corrosion, are in a
generally good condition.
A strategic maintenance plan for
Transnet pipelines' assets has been compiled, and ongoing maintenance
projects are monitored by a steering committee to ensure that the
pipeline system and its peripherals are continuously improved upon.
pipelines is structured and manned in such a way that it can optimally
manage its own network and grow. Our experienced and dedicated workforce
is ready and able to face the diverse challenges and play the role as
expected of Transnet pipelines and the various stakeholders.
