Ultrasonic testing (UT) for tube thickness in black liquor recovery boilers: Part I - Guidelines for accurate tube thickness testing Part II - Default layouts for tube thickness surveys in various boiler zones
|Publication Date:||1 January 2015|
This TIP is a review of general considerations related to UT thickness testing of black liquor recovery boiler tubes:
Part I of this TIP provides guidelines and procedures for acquiring accurate ultrasonic thickness readings on boiler tubes, where the tube material and condition are conducive to such non-destructive thickness testing.
Part II describes how tube thickness surveys are commonly laid out for different zones of a typical recovery boiler. It also stresses that a customized survey is essential for each boiler.
