- Piping which has a wall thickness less than the recommended thickness for the pumping design pressure should not be used.
- All pipeline segments shall be clearly identified with a permanently fixed unique identification mark or number, prior to being placed in service, showing the details required in accordance with
AS 1418.15 Cranes (including hoists and winches) concrete placing equipment (non-Queensland Government link) . - The pipe logbook shall record wall thickness and pressure details, in accordance with AS 1418.15 Cranes (including hoists and winches) concrete placing equipment (non-Queensland Government link) .
