Demonstration Test Result with Semi-Flush Casing Pipe

Development of FRP casing pipe for liquefaction horizontal excavation

Abstract

This report is a petroleum gas mining corrosion resistant high pressure tube and describes the verification test result of liquefaction horizontal excavation applying the GPI standard semi - flash coupling fitting RTC 8 / inch coupling. The obtained results confirmed that it is possible to lay a 5-inch pipe with a radius of curvature of 10 m, by drawing in the liquefied ground by a semi-flash coupling pipe.
