RE: Piping Erection

looks like it mark. i have not seen one since the CAD becomes popular. Now all i see are iso's (afc approved for construction)- both for shop fab and field erection. Flour Daniel, Abb Lummus, Toyo, Mitsu and lot of others do show the FW (field welds) symbol. u can't schedule the hydro, nde and handover of the system if you can not track all completed field welds . the reference is normally the iso's.
