The mobility of the equipment used in this process means that lining of existing or new pipelines is not limited to the workshop. The scale of onsite lining that can take place was demonstrated in the construction of the 304km underground pipeline (300 NB) carrying zinc concentrate which was internally lined and installed onsite by PIHA
for the Pasminco Century Mine in North-West Queensland.
This pipeline had an operating pressure of 20,000 kPa.
Using this technique pipes with internal diameter between 25mm and 1200mm can be lined to maximum section lengths of 1300 metres – depending on the terrain, diameter, condition of the steel and bends.
PIHA
own and operate an extensive array of specialist pipeline and lining plant equipment which allows us to customise all projects undertaken to your exact needs and specifications. If you believe that a PIHA
lining system could benefit your project or would like further information please contact us at our Bibra Lake office.
