Expandable Pressure Pipe Renewal Systems Employing Polyethylene Terephthalate (PET)
1 Scope
1.1 General
1.1.1 This Standard covers expandable pressure pipe renewal systems employing polyethylene terephthalate (PET) intended for use in water supply pipes ranging from DN 15 to 50 (1/2 to 2
NPS) and specifies requirements for materials, physical characteristics, performance testing, and markings.
1.1.2 Polyethylene terephthalate (PET) pipe renewal systems covered by this standard are intended for application in various pipe materials including but not limited to lead, copper, galvanized
iron, steel, and plastic.
1.1.3 The pipe renewal is achieved by forming a thin‐walled layer close‐fitting to the interior of the existing pipe.
Note: Information on the pipe renewal system, the installation of the pipe and the manufacture and quality assurance of the pipe, is provided in the Informative Appendices A, B and C respectively.
1.1.4 This Standard covers expandable pressure pipe renewal systems employing polyethylene terephthalate (PET) and does not cover cured in place, pulled in place, pipe bursting, internalpipe epoxy lining or any other pipe lining systems.
