Abstract

Specifies requirements for the design, materials and in-service performance of Type R and Type F mechanical clamps for water industry purposes.

Scope

This Standard specifies the requirements for the design, materials and in-service performance of Type R and Type F mechanical clamps for water industry purposes.
In this Standard—
(a) Type R clamps are designated for applications involving rigid pipes, typically ductile iron (DI), grey cast iron (CI), steel (S), asbestos cement (AC), copper (CU) and reinforced concrete (RC); and
(b) Type F clamps are designated for applications involving flexible pipes, typically oriented polyvinylchloride (PVC-O), modified polyvinylchloride (PVC-M), unplasticized polyvinylchloride (PVC-U) and glass reinforced thermoplastics (GRP).
Clamps complying with this Standard are intended for use in off-take connections on pressure pipelines of the sizes up to and including DN 600, and repair applications on pressure pipelines of all sizes, with a maximum operating temperature of 40ºC.
This Standard does not cover the following:
(i) The use of repair or off-take clamps on polyethylene (PE) pipelines.
(ii) Tapping bands/saddles.
NOTE: Tapping bands and saddles area covered in AS/NZS 4793 or AS/NZS 4129.
