ISOGEN Symbol KeysOverviewThis document is intended to comprehensively cover all current ISOGEN SKEY symbol shapes. Below is a brief description aboutSKEY’s and some further information to help understand SKEY construction.All components generated by ISOGEN are defined by a unique code called an SKEY (symbol key). All components have a 2 to 4letter SKEY, the first two characters define the type of component it is and if the component can have different end types such asflanged, butt weld, screwed etc. then these are defined by the last two characters. The ** characters in the SKEY may be replaced for an appropriate end condition from the following: BW for Butt Weld CP for Compression SW for Socket Weld FL for Flanged SC for Screwed PL for Plain End LN for Liner/Nut LC for Liner/Clamp LR for Reducing Liner/Nut MP for Male Part PF for Push Fit GL for Glued CL for Clamped FA for Flared BS (or SB) for Ball and Socket (used on fixed length type pipe work) GF for Gland (used on fixed length type pipe work)The @ character in the SKEY may be replaced with an integer value in the range 1 to 9 to denote the number of segments.The character in the SKEY may be replaced with an integer value in the range 1 to 9 to denote the bend radius. This is foridentification only and will not be used for pipe length calculations.4Copyright 1991-2007 Alias Limited. All Rights Reserved.
