This part of prEN 14870 specifies the technical delivery conditions for bends made by the induction bending process for use in pipeline transportation systems for the petroleum and natural gas industries as defined in ISO 13623.
This part of prEN 14870 is applicable to induction bends made from seamless and welded pipe of unalloyed or low-alloy steels.
This part of prEN 14870 specifies three classes of induction bend corresponding to increasing quality requirements in accordance with the technical delivery conditions of ISO 3183 for pipe as indicated in Table 1 (see also ISO 3183-3:1999, Introduction).
Table 1 - Induction bend class and corresponding pipe standard
Induction bend class Corresponding pipe standard
Class A ISO 3183-1
Class B ISO 3183-2
Class C ISO 3183-3
This part of prEN 14870 is not applicable to the selection of the induction bend class.
This part of prEN 14870 is not applicable to pipeline bends made by other manufacturing processes.
On-land supply systems used by the gas supply industry are excluded from the scope of this standard.
