This Technical Information Paper (TIP) covers guidelines to assure that boiler tubes for new construction and
replacement, both in recovery and other boilers, are metallurgically sound and free from potentially harmful defects.
Special emphasis is placed on obtaining tubing of appropriate quality for critical recovery boiler service. This
service is defined as that in which tube leaks or failures can directly or indirectly lead to water reaching the smelt
bed in the furnace, thereby creating the risk of explosion. Noncritical service encompasses all other recovery boiler
tubing and power boiler tubing where leakage can result in increased safety risk or significant service interruption.
Boiler tube materials shown in this document are specified in the American Society for Mechanical Engineers
(ASME) Boiler and Pressure Vessel Code Section II, Part A. Similar specifications are issued by the American
Society for Testing and Materials (ASTM).
