Water Liner Installation – City Deep May 2017 – Water

The drinking water pipeline, which feeds the factories in City Deep, showed repetitive breakdowns. City Deep is an industrial suburb of Johannesburg, South Africa. It is located in Region F. There is a large container terminal of Transnet Freight Rail in operation locally as well as  cold storage units, the most significant dry port of the country and the Johannesburg Market.
 

The installation of the Primus Liner was performed and due to the flexibility of the liner, the installation of the Primus Liner could be achieved within a period of only 10 minutes.

Transported: Potable Water
Host Pipe Diameter: DN 160mm
Host Pipe Material: Steel
Operating Pressure: 16 bar, test pressure: 20 bar
Primus Line® System: DN 160
Total Length: 80 m

Sasol Secunda Fire Water Pilot Project – Refinery Main Fire Hydrant Water Supply

         

Client problem and challenges:

The client’s main fire hydrant system is based on recovered industrial water and this type of water speeds up the corrosion of the pipelines thus 2 sections of the pipeline developed leaks and caused water losses, the 2 sections were situated under a 4 lane access road and a very busy parking in the interior of the refinery.

Solution:

Khuduyane Quigley presented the Primus Line technology and the fast turnaround times without the need to excavate busy roads and crucial access points and parking in the refinery. The host pipe was cleaned before the inserting of the liner due to growth in the pipelines caused by the recovered industrial water. The quick insertion times and installation, no need for long excavations across the road at unsafe depthsmade the Primus Line option the fastest, safest, environmentally friendly solution. The complete solution of connecting 2 diameters of pipelines back into operation with the aid of an HDPE made spool piece.

Project details:

Sections: 2
Diameters: DN250 DN400
Total Meters: DN250 35m DN400 84m
Installation time 6 working days including cleaning and pipeline inspections.

ATE Boksburg Primus Line Drinking and Sprinkler Water Rehabilitation

Client problem and challenges:
The main pipeline water supply at ATE was found to lose between 20-30000 litres of water per night due to numerous pinhole leaks and the pipe being more than 40 years old and in a very bad overall condition.

The pipeline is running from the main factory gate under the truck weighbridge for 44m turning right at a 45 degrees angle for 15m then left at 30 degree angle toward the factory for 16m.

Excavating to replace and installing a new pipeline would have meant days possibly weeks of no water and the added expenses of new pipeline, excavation, installation times etc.

Solution:

Rescue Rod Pty Ltd presented to the Client the new Primus Line technology which can rehabilitate a pipeline without obstructing the busy factory traffic, the collecting and deliveries from the warehouse and the weighbridge usage. Primus Line is apart from other technologies as the liner can be used in a pipeline with bends and with quick insertion times and fast re-commissioning. Added to the surface known challenges when exposed the water pipeline was next to and very close to storm water pipelines which added to space restrictions and confirmed that the best solution was lining with Primus Line and not installing a new pipeline.

Project details:
Total Meters: 75m with 2 bends. Liner diameter: 150mm
Installation time 3 working days due to client requirements with regards to access of the trucks in the driveway.
