This part is drafted in accordance with the rules given in GB/T 1.1-2009.

1 Scope

This part of GB/T 21412 specifies the design, material selection, prototype testing, manufacturing, and loading of flexible pipe systems in underwater production systems.

Basic requirements for unloading, transport, installation, recycling and reuse, and integrity management.

This section applies to flexible pipe systems and their associated components, including flexible pipe body and end fittings fitted to both ends, suitable for static and Dynamic bonded and non-bonded flexible pipes, such as oil pipes, risers, jumpers and other temporary applications for flexible pipes, can also be used in offshore oil discharge systems.

This section does not apply to choke pipes, kill pipes or umbilicals and flexible pipes for control pipes.
