cfiXML Engineering Data Exchange Files

WORKING RELEASE V 4.01 - ISSUED 23 February 2012.

Full Notes on cfiXML schema updates for Working Release v 4.01 and undertaken since Public Release 4.00 (6/29/11) are provided in WRelease4.01Notes.htm.

The work undertaken primarily extends schema to cover requirements for the procurement of Rotary pumps (specified in API 676 data sheet).  Some additions were also made for control valves, including motor-operated valves (MOVs).

Two downloads are available: cfiXmlFull_WorkingReleaseV4.01.zip and cfiXmlLT_WorkingReleaseV4.01.zip.  The former is the full standard cfiXML schema.  The latter cfiXML Light (LT) schema has been available since Public Release v4.00 to support the use of simple XML serialization tools and enable developers with limited XML experience to be able to develop data exchange systems easily and cost-effectively.  For further information see cfiXML_LT_Specifications available from cfixml.org.

Key Edits
1) for ROTARY PUMPS Bid Quote and RFQ

a) Schema updates have primarily involved the development of a rotary pump element, which previously only existed as a basic schema object with no detailed specifications.  Data items required by both centrifugal and rotary pumps need to be inherited from the base type pump.  So many of the new requirements for rotary pumps involved assessing which existing data items in centrifugal pumps needed to be moved into the base type pump. New data only applicable to rotary pumps was also added.

b) Renaming definition files
A significant number of data items shared between centrifugal and rotary pumps indicated that both pump types can be included in the same file so eqRotCPmp.xsd is renamed to eqRotPmp.xsd.
Similarly eqRotCFan.xsd is renamed to eqRotFan.xsd, so fans other than centrifugal fans can be placed in the eqRotFan,xsd  (discussed MantisBT issue 046).

c) Updates to impeller object location [FOR ROTARY AND OTHER EQUIPMENT ITEMS]
Rotating equipment items are extended from eqRot:RotatingEquipmentItem.  Development of rotary pumps highlighted that eqRot:Impeller in the eqRot:RotatingEquipmentItem base sequence was not appropriate content for a significant number of rotating equipment items (impellers are not components).  A better representation of the equipment items is achieved by moving the eqRot:Impeller object from the shared base sequence.  Reference to the eqRot:impeller element is added into appropriate engineered equipment items. These include centrifugal pump, centrifugal fan and centrifugal compressor (and associated compressor section) and rotary blower, as shown below. 
(Impellers have effectively been removed from reciprocating, axial, rotary, screw and scroll compressors; axial fan; rotary pump, reciprocating pump, controlled volume pump, turboexpander, vacuum pump.)

2) for CONTROL and MOTOR OPERATED VALVES Bid Quote
A few key schema updates were required, the most significant of which is the provision of the electric motor object for motor actuated valves.
