PAPER MACHINE REEL SPOOL JOURNALS: GUIDELINES FOR THE IN-SERVICE INSPECTION TO DETECT CRACKING AND REPAIR/REPLACEMENT CONSIDERATIONS

• These guidelines have been developed by a TAPPI Task Group to provide information regarding nondestructive testing (NDT) of reel spool journals. They provide background information about reel spool failures, inspection, and design/re-design as well as considerations for repair/replacement.
• This document provides information to assist owners in establishing an inspection program to detect cracking and prevent reel spool journal failures. It contains information on failure location, failure mechanism, inspection frequency, nondestructive testing (NDT) methods and techniques, journal materials, etc.
• Experience has shown properly designed and carefully manufactured reel spool journals have operated for 30 years.
• The frequency of inspections will vary as each mill and machine has different operation conditions.

It Provides information on:

• Safety precautions.
• Design and material selection.
• Failure location, characteristics and mechanism.
• Inspection.
• Repair.
• Replacement.

Who will benefit:

• Quality Manager.
• Engineers.
• Maintenance Manager.
• Safety Manager.
• Supervisor.
