CONSTRUCTION OF AN EXPERIMENTAL SECTION OF GAS PIPELINE OF FERRO-CONCRETE WITH PARAFFIN SEALANT

In experiments with ferro-cement pipe, gas permeability was practically eliminated by treatment with melted paraffin at 220 psi for 90 min. A 100 ft section of paraffin-sealed 27 in. pipeline was constructed using rubber sealing rings which permitted small longitudinal and angular movement. Pneumatic pressure tests showed a drop from 177 to 175 psi in a 24 hr period. Computations and experiments proved the technical possibility of producing ferro-cement pipes for working pressures up to 440 psi. Ferro-cement pipelines may have advantage for LNG lines, for Arctic pipelines, for gas mains, or for sections of pipelines just upstream from compressor stations. Production cost is estimated as 67% that of steel, construction cost 80%, and operating costs 86%.
