3.1

actual yield strength

yield strength of material determined from specimens directly related to components used in construction of the test samples

3.2

application level

service loading envelope encompassing a group of pipeline and riser applications

3.3

batch

group of items manufactured or machined under controlled conditions to ensure consistent chemical composition, processing and heat treatment such that the group can be considered as a single population

3.4

by agreement

unless otherwise indicated, agreement between the manufacturer and purchaser at the time of enquiry and order

Note 1 to entry: Adapted from ISO 3183-2:1996.

3.5

connector

mechanical device used to connect adjacent components in the pipeline

3.6

galling

localized damage to material surfaces resulting from contact conditions

Note 1 to entry: Galling can be caused by cold welding of contacting material surfaces followed by tearing of the weld during further sliding or rotation.

3.7

heat, noun

batch of steel prepared in one steel-making operation

[SOURCE: ]

3.8

liner

internal layer of a material different to that of the pipe body

Note 1 to entry: The liner material may be, for example, plastic or non-ferrous.

3.9

load envelope

limit of loads (axial, pressure, torsion, bending, fatigue and temperature) within which a connector operates during service or is tested

3.10

manufacturer

organization responsible for the design and manufacture of the equipment

Note 1 to entry: The manufacturer is not necessarily the vendor.

Note 2 to entry: Adapted from ISO 13707:2000.

3.11

operational restrained test

simulation of the loads due to operational cycling on a section of pipeline that is fully axially constrained

3.12

operational unrestrained test

simulation of the loads due to operational cycling on a section of pipeline or riser that is not axially constrained and may have axial tension due to self-weight or externally applied tension

3.13

pipeline

those facilities through which fluids are conveyed, including pipe, pig traps, components and appurtenances up to and including the isolating valves

[SOURCE: ISO 13623:2000]

3.14

purchaser

individual or organization that issues the order and specification to the vendor

Note 1 to entry: The purchaser may be the owner or the owner's agent.

3.15

reverse torque

Z

torque applied during tests to simulate loads that might cause the connector to rotate or unscrew, if applicable

3.16

riser

that part of an offshore pipeline, including subsea spool pieces, which extends from the seabed to the pipeline termination on an offshore installation

[SOURCE: ]

3.17

seal

barrier that resists the passage of fluids

[SOURCE: ]

3.18

multiple seals

sealing system that consists of more than one independent barrier and of which each barrier forms a seal itself

3.19

specified minimum yield strength

minimum yield strength required by the specification or standard under which the material is purchased

[SOURCE: ]

3.20

test sample

assembly of a connector and two pieces of pipe specifically for testing
