GB/T 31468-2015 — The ISO 13623 standard gives an assessment as defined in the piping system design life beyond the minimum requirements of the feasibility of continuing the service guide then.
The standard pumping station shown in Figure 1, compressor stations, pressure reducing stations and reservoirs do not have any specific requirements.
This standard applies to rigid metal pipes, does not apply to the following. a) a flexible pipe; b) Other material conduit, such as glass pipes; c) umbilicals; d) platform superstructure and facilities; e) structures and structural components.
As an example of the standard of the original design changes, only for pipeline life extension. It does not include other changes, such as increased MAOP. NOTE.
After careful consideration of the user, this method can be used to assess other design changes. 1 piping systems range covered by this standard
