flang. rating designation
:PN series: alphanumeric designation that is used for reference purposes, relating to flange pressureiternperature capability, taking vito account flange material mechanical properties and component dimensional characteristics, comprising the letters PN followed by a dimensionless number
NOTE I The number following the letters PN does not represent a measurable value and is not used lot calculation purposes except where specified in a relevant standard Reference to PN is meaningful only when I Is related to a relevant component The use of the designation PN Is applicable to all steel flanges bearing nominal size designations DN.
NOTE 2 It is the intent that flange end equipment of the same noninal size (DN) designated by the same PN number have compatible mating dwnensions.
NOTE 3 The maximum allowable presse for a flange having a PN number depends on the flange material arid its application temperature and is to be found fri tables at pressureltemperature ratings Wi the reference flange standard
NOTE 4 Adapted from ISO 7268.
flange rating designation
(dass series) alphanumeric designation that is used for reference purposes, relating to flange pressure/temperature capability, taking into account flange material mechanical properties and component dimensional characteristics comprising a dimensionless number that is frequently preceded by the word
NOTE I The designation rsimber does not represent a measurable value and is not used for calculation purposes except where specified ii a relevant standard. Reference to a class is meaningful only when it is related to a relevant component. The use or the designation class is applicable to al steel flanges bearing size designations NPS.
NOTE 2 It Is the intent that all flange end equipment of the same nominal size (NPS) designated by the same class number have compatible mating dimensions,
NOTE 3 The maximum alfowable pressure for a flange having a class number depends on the flange material and its application temperature and is to be found in tables of pressure?temperature rati’igs ii the reference flange standard.
flange series series
classification system for flange designs having a common derivation
NOTE I This part of ISO 7005 specifics flanges of two series: PN series and class series.
NOTE 2 Ills the intent that all flange end equipment of the same series having the same rating designation and the same nominal size have compatible mating dimensions
flange style style
name used within a flange series for designating dimensional features usually relating to an attachment method
EXAMPLE Threaded, socket, slip-on, lapped. blind or waking neck.
fluid service category
category concerning the application of a pipiog system, considering the combination of fluid properties. operating conditions and other factors which establish the basis for design of the piping system as determined by the purchaser
individual or organization that takes responsibihty for the manufacture of flanges in accordance with the purchase?s Instructions and in accordance with the requirements of this part of Iso 7005
NOTE 1 Tho manufacturer is not responsible for the selection of gaskets or bolting.
NOTE 2 If a manufacturer employs sufcontractors for rtain tasks, he is deemed to retain full control over their work
NOTE 3 Adapted from ISO 15649.
minimum application temperature
lowest temperature of the flowing fluid at the mid-thickness of a piping wall to which a flange Is attached, as determined by the purchaser
minimum application temperature
when specified by the user it may be the lowest service temperature at the mid-thickness of a piping wall to which a flange is attached
individual or organization responsible for establishing the requirements for design, construction, examination, inspection and testing that govern the Iked handling or process facility of which the flanges is part
NOTE The owner is responsible for the selection of gaskets and bolting as well as the assembly of flanged joints.
assembly of individual pieces or stages of equipment, complete with interconnecting piping using flanges for connections in external piping
NOTE 1 The assembly may be mounted on a skid or other structure poor to delivery.
NOTE 2 The owner can be the individual or organization that purchases flanges an&or. more often than not, that is responsible for operating the facibty.
NOTE 3 Adapted from ISO 15649
pressure-tight cylinder to which flanges may be attached, used to convey a fluid or to transmit a fluid pressure
NOTE 1 Pipe is ordinanêy designated plpe in applicable material specibctlons. Materla designated tube or tublng In the materiel specifications are often treated as pçe tien Intended for pressure service.
NOTE 2 Adapted from ISO 15649.
