Full title and description
Standard Practice for Installation of Machine Spiral Wound Poly (Vinyl Chloride) (PVC) Liner Pipe for Rehabilitation of Existing Sewers and Conduits — a practice that sets out procedures for fabricating, inserting, expanding (or installing fixed-diameter) and grouting spiral-wound PVC liner pipe for the trenchless rehabilitation of non‑pressure sewer and conduit systems.
Abstract
This practice describes methods for field fabrication and installation of machine spiral‑wound PVC liner pipe (using either a stationary winding machine in the insertion pit or a traveling winding machine) for rehabilitation of existing gravity sewers, storm sewers, culverts and similar conduits. It covers installation options that produce either a close‑fit (expanded) liner or a fixed‑diameter liner with annular space grouted, and notes safety considerations such as confined‑space work.

Scope
The standard covers rehabilitation of existing pipelines and conduits from approximately 6 in. to 180 in. in diameter by insertion of a machine‑made, field‑fabricated spiral wound PVC liner using either stationary or traveling winding equipment. For stationary equipment (typically for smaller diameters up to about 48 in.), the liner may be expanded in place to press against the host pipe; alternatively the liner may be installed at a fixed diameter and the annular space grouted (options vary by diameter range). The practice is intended for gravity (non‑pressure) applications including sanitary sewers, storm sewers, culverts and similar conduits and emphasizes that job‑specific modifications and appropriate safety procedures (e.g., confined‑space precautions) may be required.
Key topics and requirements
- Machine spiral‑wound PVC liner fabrication and field winding techniques (stationary vs. traveling winding machines).
- Diameter ranges for application (nominally 6 in. to 180 in.) and guidance on when to expand a liner versus install fixed diameter and grout annulus.
- Material considerations — PVC profile strip / PVC liner components suitable for spiral winding.
- Insertion methods, expansion procedures, and grouting of annular spaces where specified.
- Inspection, acceptance criteria and responsibilities of designers/specifiers, owners and inspection organizations.
- Safety and environmental precautions, with particular attention to confined‑space entry and work practices.
- Use of inch‑pound units as standard (SI conversions provided for information only).
Typical use and users
Primary users are municipal engineers, designers, contractors and specifiers working on trenchless rehabilitation of sewers and conduits, plus owners, regulatory authorities and inspection bodies who define acceptance criteria and oversee installations. The practice is applied to rehabilitation projects for sanitary sewers, storm sewers, culverts and similar gravity conduits where spiral‑wound PVC liners are appropriate.
