Note:
|
1 |
The positions of P3 and P4 along the vertical axis are important for deriving correct cut pipe lengths. The vertical displacements of P3 and P4 are determined by the points at which the offline legs intersect the main line. P0, P1, P2, P3, and P4 will be coincident when the offline leg has the same bore as the main line. |
|
2 |
The dimensions of all Cross components depend upon plotted leg length. The default plotted leg length is 9mm, but the user can set this to a different value using the LEGLENGTH command. The minimum value the user can set is 6mm. |

Replace the ** characters in the symbol key with one of the following end condition identifiers: BW for butt weld CP for compression SW for socket weld FL for flanged SC for screwed PL for plain |
|
4 |
The @ character in the symbol key is replaced automatically by an integer in the range 1 to 4, depending on the relative bore size of the connections, with 1 assigned to the largest bore. It is important to note the bore size if redefining the SKEYS for X1**, X2**, X3** or X4**. |

Flanged connections on generic Y-type fittings are represented on the isometric on the tube only. This is due to the fact that the y-type fitting is user-definable and flanged representation on the component cannot be enforced. ELBO or BEND Symbol Keys |
