Striping and jacketing compounds form an integral part of PE100 piping solutions, identifying the fluid that is transported or in the case of white jackets ensuring pipes installed above ground do not heat up excessively in the sun.

The PE100 HSCR pipe system is based on a high stress-crack resistant PE100 resin such as Alkadyne HCR193B and delivers step out resistance to slow crack growth, thus making it suitable for demanding applications such as trenchless installation, the use of courser backfill or when rough handling is expected during transport. Striping and jacketing forms an integral part of the pipe wall and plays an important role in the structural integrity of the pipe during transport, storage, installation and in service.   It is therefore of utmost importance that striping and jacketing compounds also comply with the same stringent requirements as the PE100 HSCR base resin.

Qenos offers a full range of striping and jacketing compounds for identification of PE100 HSCR pressure pipes. Alkadyne HCR193 striping and jacketing compounds are manufactured from a base resin that complies with PE100 requirements outlined in AS/NZS 4131 and PIPA POP016 for high stress crack resistance (HSCR) polyethylene compounds. The striping compounds meet requirements for “Striping and Jacket compounds” outlined in AS/NZS 4130 Section 7.3 as well as PIPA guideline POP017 for HCR193WTE.

Alkadyne HCR193 striping and jacketing compounds offer outstanding toughness expected from a PE100 HSCR compound and have excellent resistance to the effects of ultra-violet light exposure during prolonged pipe storage. They have been used in a variety of projects across Australia to identify various pipe applications including potable water mains and reticulation, coal seam gas and sewer rising mains. They are not intended for solid wall coloured pipe applications.

Certain water asset owners in Australia are requiring PE100 piping materials to be resistant to disinfectants and feature high stress-crack resistance (PE100 RCD). While disinfection resistance is not required for a striping compound as it is not in contact with water containing disinfectants, it is important that the stripes feature high stress-crack resistance. This is recognised by asset owners who require striping compounds for PE100 RCD piping to be compliant with AS/NZS 4131 and PIPA guideline POP016. Alkadyne HCR193 striping and jacketing compounds are therefore suitable for the manufacture of striped PE100 RCD pipes when used in conjunction with a PE100 RCD black base resin.
