TIP 0402-30 "Inspection for cracking of composite tubes in black liquor recovery boilers" has been withdrawn by the Quality and Standards Management Committee (Q&SMC), due to lack of progress in its regular review. Q&SMC may withdraw TIPs that are periodically reviewed if no progress has been made within a year of the targeted completion date.
Withdrawn TIPs are available free for TAPPI members and for a $10 charge to nonmembers.
Anyone wishing to open a Work Item for reinstatement of withdrawn TIPs should contact standards@tappi.org.
