Purpose

This part of ISO 13628 defines the technical requirements for safe, dimensionally and functionally interchangeable bonded flexible pipes that are designed and manufactured to uniform standards and criteria. See Figure 1 for explanatory figure on typical bonded flexible pipe.

Minimum requirements are specified for the design, material selection, manufacture, testing, marking and packaging of bonded flexible pipes, with reference to existing codes and standards where applicable. See API RP 17B for guidelines on the use of flexible pipes and ancillary components.

Products

This part of ISO 13628 applies to bonded flexible pipe assemblies, consisting of segments of flexible pipe body with end fittings attached to both ends. This part of ISO 13628 does not cover flexible pipes of unbonded structure. See ISO 13628-2 for guidance on unbonded flexible pipes.

NOTE For the purposes of this provision, API Spec 17J^[10] is equivalent to ISO 13628-2.

This part of ISO 13628 does not apply to flexible pipe ancillary components. Guidelines for ancillary components are given in API RP 17B.

This part of ISO 13628 can be applied to flexible pipes that include non-metallic reinforcing layers, though no effort was made to address the specific and unique technological aspects of this product.

This part of ISO 13628 can be applied to a bonded construction pipe that includes a material or layer construction that is covered in ISO 13628-2.

NOTE For the purposes of this provision, API Spec 17J^[10] is equivalent to ISO 13628-2.

Applications

The applications addressed by this part of ISO 13628 are sweet and sour service production, including export and injection applications. Production products include oil, gas, water and injection chemicals. This part of ISO 13628 applies to both static and dynamic flexible pipes used as flowlines, risers, jumpers and offshore loading and discharge hoses. This part of ISO 13628 applies to pipes with a design pressure greater than or equal to 1,5 MPa (15 bar). This part of ISO 13628 can be used for lower design pressure pipes, though the requirements of these pipes have not been specifically addressed. Reference OCIMF^[30] for guidelines on these pipes.

This part of ISO 13628 does not apply to flexible pipes for use in choke and kill line applications. See API Spec 16C for guidance on choke and kill line applications. This part of ISO 13628 can be applied to flexible pipes for pile hammer, gas flare, water supply and jetting applications, though no effort was made to address the specific and unique technological aspects relating to each of these requirements.
