Two grades of SABIC Vestolen A RELY are currently available, both typically suitable of producing pressure pipe that meets the PE 100 standard. SABIC Vestolen A RELY 5924R delivers good low sag performance for large-diameter pipes and pressure pipes with a low standard dimension ratio (SDR).
SABIC Vestolen A RELY 5922R helps customers meet the stringent slow crack growth requirements for pressure pipe, enshrined in PAS (Publicly Accessible Standard) 1075. Certification to PAS 1075 enables the grade to be used for pipes intended for installation using the most demanding techniques, including new trenchless methods such as guided boring and horizontal directional drilling.
These methods have a reduced impact on the environment, but they are more demanding of pipe properties, since surface damage during the installation process is more likely to occur.
