1 Scope
This International Standard 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 International Standard is applicable to induction bends made from seamless and
welded pipe of unalloyed or low-alloy steels.
NOTE These are typically C-Mn steels or low-alloy steels that are appropriate for the corresponding level and grade of line pipe in accordance with ISO 3183.
This International Standard specifies the requirements for the manufacture of two
product specification levels (PSLs) of induction bend corresponding to product specification
levels given for pipe in ISO 3183.
This International Standard is not applicable to the selection of the induction bend
product specification level. It is the responsibility of the purchaser to specify the PSL, based upon the intended use and design requirements; see also
ISO 3183:2007, Introduction.
This International Standard is not applicable to pipeline bends made by other manufacturing
processes.
On-land supply systems used by the gas supply industry excluding gas infrastructure
from the input of gas into the on-shore transmission network up to the inlet connection
of gas appliances are excluded from the scope of this standard.
