The rapid development of Asia and the Middle East, has called for an equally rapid
expansion of their infrastructure networks. At the same time, increasing urbanization
has led to an increased use of trenchless technology for the installation, replacement
and renovation of infrastructure of pipelines. Trenchless technology applications
increase the risk of pipes being damaged during installation and / or being subjected
to significant point loads after installation. These are conditions which can lead to the
initiation of cracks in the pipe wall and the subsequent propagation of the cracks
through the slow crack growth (SCG) mechanism. Several polyethylene resin
manufacturers, including Borouge, have developed High Stress Crack Resistant
(HSCR) PE100 grades (PE100RC) which have a much higher resistance to SCG.
Borouge has supplied HSCR PE100 for use on a range of challenging project over
the last 2 years. These have included lining slurry pipelines in Australia, the lining of
water injection and oil flow lines in the oil fields of the Middle East, horizontal
directional drilling projects in China and New Zealand and the laying of pipes in the
mountains of Afghanistan. This paper provides a background to HSCR PE100
including how to measure the material’s performance and then discusses Borouge’s
experience in introducing HSCR PE100 to pipe producers and end users in the
region before providing details of four projects on which the material has been
employed, together with detailing some of the lessons learnt along the way.

Seismically active faults pose a risk to buried water pipelines that can be complicated
to quantify. Fault type, slip rate, pipeline geometry, and soil conditions all factor into a
complex soil-pipeline interaction. For critical pipelines that cross faults, high-density
polyethylene (HDPE) has become an attractive...

This study investigates production of crosslinked polyethylene (PEX) pipes using a resin obtained from a renewable resource via twin-screw extruder technology. PEX pipes were extruded using petroleum-based and renewable high-density polyethylene (HDPE) for comparison. Testing using relevant ASTM standards on the new...

Developments in material and pipe extrusion technology now enable converters to produce PE100 solid wall pipes of up to 2,800mm OD, but the use of such large diameters has been limited to industrial applications. This is now starting to change with water transmission pipelines of up to 1400mm OD being laid in the UAE...

The Star Energy Wayang Windu geothermal plant in Java, Indonesia, generates up to 227MW of electricity using the natural steam from deep beneath the earth. Once the steam has cooled and condensed it is returned to the underground reservoir through condensate pipelines and injection wells. By 2012 the existing steel...

Often plastics get a bad press due to poor quality products and the mishandling of plastic waste. But when high quality pipe systems are employed, they can significantly improve the lives of people living in poor communities around the world. The success and sustainability of such projects is also often down to...
