Esor Pipelines have established themselves as a leader in the application of pipeline coatings and linings. With in-house inspectors and applicators, Esor Pipelines are able to offer clients complete peace of mind with respect to mechanical linings and coatings.

Esor Pipelines' experience in this field are mostly with (but not restricted to), the following products:

  • Cement mortar lining
  • Fusion bonded epoxy linings and coatings
  • Bitumen fibre glass coatings
  • Three layer coatings
  • Tape wrapping

For unlined new pipelines, Esor Pipelines uses specialised equipment to install Cement Mortar Lining (CML) post-construction. On existing pipelines, the existing linings are removed by high pressure water jetting and then dried using drying "pigs" before being Cement Mortar Lined "in-situ".

Stack yard lining of pipes consists of Cement Mortar Lining the pipes, in individual lengths, in a stockpile before installation.

Installation of epoxy linings is provided either in-situ (after the laying is complete) or in the stack yard.

Due to Esor's market share in the pipeline industry, close relationships have been struck with the manufacturers and suppliers of the various corrosion protection products, enabling them to keep up with modern techniques and advances.

Esor Pipelines have the resources and expertise to carry out testing of pipelines to pressures up to 150 bar. This is expedited by sealing test sections of the pipeline before it is filled with test media such as water or air.

The pipeline is then pressurised to the specified test pressure and allowed to stand at the specified pressure for a specified period. 

Services further include pigging of lines as required (brushing, swabbing, gauging, de-watering, drying etc.) using water, dry air or chemical swabs as specified.

Esor Pipelines are proud to be associated with World leaders in the supply of valves for all applications. Our strong ties with these Companies allow us a competitive advantage in terms of the procurement of valves which are often imported from abroad.

Esor Pipelines have, over the years gathered the expertise to successfully install valves of varying application and specification. 
The manufacture of specials such as bends, tees and flanged stubs is for the most part carried out in-house by Esor Pipelines again affording Esor a competitive edge over its competitors. 

 

Flagship Projects

We have been awarded the Construction of the F46 Pipeline:  Earthworks, Pipe laying and Associated works for the construction of a 4km long 1424mm ID (12mm thick) steel pipeline from Whiteridge Waterval to the Weltevreden Reservoir awarded by Rand Water.

The pipeline was awarded in two sections where Esor Construction will construct portion A and Maziya General Services will construction portion B.  Under Portion A, Esor Pipe Services have been awarded 4 road jackings of which 1 is complete and the remainder expected to be completed before the end of March 2017.  The Jacking at Maluti street was increased from 17m to 29m to pass existing structures which obstructed the pipeline route.  The jack closest to the Weltevreden Reservoir is being extended from 21m to 75m to mitigate the uprooting of a major storm water pipe.

Additional jacking of 30m is planned, next to a residential building where excavation for the pipeline cannot be done, but we can provide the solution.

Construction activities will start the 3rd May 2016 and the expected completion date will be 31st October 2017.

The Nandoni Bulk Pipeline project was awarded to Esor and started in December 2015.  This is our third project awarded in Limpopo following the opening of our office early 2015.

The contract comprises the construction of the bulk pipeline from Vuwani NR6 reservoir up to Majosi reservoir.

This involves the installation of a bulk water pipeline of 800 mm diameter continuously welded steel pipe, with a 3 layered coating and epoxy lining.  Major activities are :  construction of river and road crossings;  the connection at Vuwani pump station (NR6 reservoir);  connection to Majosi Reservoir and draw-off point provided for at Vyeboom/Kuruleni.

The project end date is set for August 2017 with a contract value of R231 million.

Our pipelines division is well on course to completing the installation of a pipeline connecting the Xonxa Dam to the Queenstown water treatment works.

This Eastern Cape project is a component of the greater Xonxa Dam transfer scheme and bulk water supply project commissioned by the Chris Hani Municipality to increase Queenstown’s bulk water supply.

The 22,3km DN 600 cement-lined steel conduit will not only help relieve present water shortages within the urban area but will provide a much needed supply of potable water to residents of underdeveloped rural areas.

An extensive range of tasks are associated with the project. Among these are site clearance, connections to the pump station delivery line and reservoir intakes as well as the execution of road and river crossings. The route also includes two above-ground sections, and traversing a ridge – a vertical gain in height from the pump station of 400m.

Important environmental and cultural considerations were the identification and protection of two very old trees and the preservation of bushman paintings and a site that was used to make stone tools.

The team, which is expected to complete the project by September, is made up of 30 core Esor Pipelines personnel, including operators, welders, foremen and supervisors. These numbers are augmented by 165 local recruits who have received training in pipeline construction.

The cooperation between contractor and client has been excellent, says Director Arné Rheeder.

"This is our first project for the Chris Hani District Council and we are delighted to be partnering with such a progressive and forward-thinking organisation on an important project like this."
