ISO 21051 specifies the recommended practices and requirements for the installation of a buried and above-ground ductile iron pipeline system conforming to ISO 2531, ISO 7186, and ISO 16631.
The recommended practices in ISO 21051 are intended to provide practical advice based on the best methods of construction and installation of ductile iron pipeline systems including pipes, fittings, valves, and accessories.
ISO 21051 on construction and installation of the ductile iron pipeline system is relevant to:
A ductile iron pipe is a pipe made of ductile cast iron commonly used for potable water transmission and distribution.
ISO 21051 provides information on occupational safety and health requirements, materials in contact with water intended for human consumption, input control, transport, handling and storage of pipeline components and inspection, coating and lining repairs, cutting of pipes, and ovality correction.
ISO 21051 provides guidance on on-site preparation, and pipe trenches, laying of pipes, push-in joints, jointing, and anchoring required for construction and installation of the ductile iron pipeline system.
A ductile iron pipeline system needs careful installation to ensure the best possible performance. ISO 21051 supplies tried and tested methods that will help users achieve high-quality installations. This results in better aesthetics, fewer immediate and longer-term problems with the installation, no premature wear of products, and fewer health and safety issues. As a user of ISO 21051, you can be ensured of a durable, corrosion resistance ductile iron pipeline that minimizes the risk of leakage and contamination.
