AS ISO 14692.3:2022
[Current]Petroleum and natural gas industries — Glass-reinforced plastics (GRP) piping, Part 3: System design
AS ISO 14692.3:2022 identically adopts ISO 14692 3:2017, which outlines requirements for the design of GRP piping systems. The requirements and recommendations apply to layout dimensions, hydraulic design, structural design, detailing, fire endurance, spread of fire and emissions, and control of electrostatic discharge.
