The writer describes the advance of the state of the art of cement mortar lining pipelines in-place, which is done by relating the history of cement mortar lining. Also description of the process is given as it is related to the material and equipment. The advantages of lining pipelines with cement mortar in-place are enumerated, and the trend toward the lining of large diameter pipelines is examined. Numerous applications of in-place cement mortar lining during the past have been described and referenced.

Corrosion and incrustation in carbon steel raw water pipelines have been found to be problems at many of TVA's fossil and nuclear plants. Lining existing and new carbon steel raw water pipelines with cement mortar conforming to AWWA C602‐76 requirements is one way to correct these problems. However, for nuclear applications, the cement‐mortar lining under seismic loading conditions must be qualified by either analysis or testing. This paper describes a TVA‐conducted full‐scale testing program to structurally quality the cement‐mortar lined carbon steel pipelines for safety‐related nuclear applications. Static and dynamic tests were carried out in the laboratory and field. After analyzing all data, it is concluded that the tests have verified the structural integrity of the cement‐mortar lining for both nuclear and non‐nuclear applications at TVA facilities.
