Overview
ISO/TS 10465-1:2007 provides comprehensive guidance for the underground installation of flexible glass-reinforced pipes made from unsaturated polyester resin (GRP-UP). Developed by the International Organization for Standardization (ISO), this technical specification addresses best practices for the installation of GRP pipes as specified in ISO 10467 and ISO 10639, and can be used as a reference for other similar GRP piping systems. The standard focuses on installation procedures, excluding jacking, relining, above-ground work, and site-specific health, safety, and environmental requirements, which are governed by national regulations.
Reliable installation practices are critical to ensuring the durability, performance, and safety of underground GRP piping used in applications such as water supply, sewerage, and drainage systems.
Key Topics
ISO/TS 10465-1:2007 systematically covers essential aspects of underground GRP pipe installation, including:
-
Installation Design Considerations:
- Site assessment, including water table level and soil stability
- Soil exploration and classification for appropriate pipe selection
- Evaluation of the locations of existing utilities and structures
-
Pipe Handling and Logistics:
- Procedures for on-site inspection, transportation, and handling to prevent damage
- Recommendations for stacking, lifting, and storing pipes and fittings
-
Trench Construction and Preparation:
- Guidance on excavation, determining minimum trench width, and managing water control
- Trench bottom support and managing trenching on slopes or challenging soils
-
Pipe Laying, Jointing, and Backfilling:
- Pipe laying techniques, quality assurance, and joining methods
- Embedment, compaction, and backfilling to minimize pipe deflection and ensure structural stability
-
Dealing with Special Installations:
- Considerations for casings, submarine pipelines, and installations in embankments
-
Testing and Disinfection:
- Methods for deflection and pressure testing
- Procedures for swabbing and disinfection of water mains
Applications
This standard is vital for engineers, contractors, and utility managers involved in the underground installation of GRP pipes for various infrastructure projects:
- Water Supply Systems: Ensures reliable, leak-resistant installation for potable and non-potable water transmission.
- Sewerage and Drainage Networks: Supports effective subterranean pipe placement for both pressure and non-pressure systems.
- Industrial Piping: Provides a framework for robust installation practices in industrial facilities where chemical resistance and structural integrity are required.
- Municipal Infrastructure: Enables local authorities to standardize installation practices for public works, reducing maintenance costs and extending service life.
- Pipeline Rehabilitation: While the standard does not cover relining, its procedural guidelines serve as a reference for new installations parallel to rehabilitation works.
By adhering to the installation procedures in ISO/TS 10465-1:2007, stakeholders can reduce the risk of pipe failure, control long-term deflection, and enhance system reliability while complying with international best practices.
Related Standards
Several key standards complement and provide the foundation for ISO/TS 10465-1:2007:
- ISO 10467: Plastics piping systems for pressure and non-pressure drainage and sewerage - GRP systems based on unsaturated polyester resin.
- ISO 10639: Plastics piping systems for pressure and non-pressure water supply - GRP systems based on unsaturated polyester resin.
