 Pipeline Crossings," Report of the Committee on PipeUne Crossings, Journal of the 

 Highway Division, No. HWl, Jan. 1964, pp. 19-52. 



Keywords: Highway pipeline crossing 



Paper summarizes highway pipeline-crossing practices. The following topics are 

 discussed: (a) Pipe location and alinement; (b) burial; (c) encasement and protection; 

 (d) vents, drains, and markers; (e) uncased carriers; (f) hazardous transmittants; (g) restric- 

 tions against varied use; and (h) design loads and stresses. Factors that should be considered 

 in the installation of a pipeline through an existing highway, or in the construction of a 

 highway over an existing pipeline, are also discussed.

 Pipeline Corrosion," Committee on Pipeline Planning, Task Force Report, Journal of 

 the Pipeline Division, Vol. 90, No. PLl, Jan. 1964, pp. 89-153. 



Keywords: Pipeline corrosion 



A summary of the results collected from questionnaires concerning pipeline corrosion 

 distributed to companies in the oil, gas, product, and water industries using pipelines is 

 presented. The information includes the selection of external pipe coatings, application of 

 cathodic protection systems, use of high-strengtli thin-waUed pipe, and the determination of 

 operating pressures on existing pipelines that have suffered corrosion deterioration. The 

 questions and responses are presented in tabular form. A list of areas that need further study 

 and investigation is given as determined from the results of the questionnaire responses.

Keywords: Pipeline flotation. Sediment 



Report discusses the problem of pipeline flotation in saturated soils and sediments both 

 during and after construction. Pipe flotation experiments were carried out to determine 

 design criteria for pipeline stability in saturated sediments. From the results of the 

 experiments, preliminary tables were developed to determine the bulk specific gravity of a 

 pipe that will not undergo flotation or sinking, for a given set of sediment conditions. The 

 tables are presented with the necessary bulk specific gravity of the pipe determined as a 

 function of the bulk specific gravity or density of the sediments, the shear strength of the 

 sediments, and the pipe diameter. Examples are given to illustrate the use of the tables in 

 calculations, and plans for further research in this area are discussed.
