As the worldwide problems are over-population, unusual weather like as localized heavy rain and climate change. Against those problem, it has to need new projects to make a new agricultural field, drainage pipeline system and to spread the new underground irrigation system at peat land whereas spots of about 2 million km 2 on the surface of earth. To use those areas as into pipeline system, it shall be affected unique characteristics as combine high ring stiffness and flexibility for longitudinal directions with long term property because to prevent maintain the flow capacity as if the ground deformation. Nevertheless it had quite difficult to provide those characteristics as mentioned to make it for large diameter. There are only PE-sGF pipe made by spiral cross winding method with orientating short glass fibres including whole those property. This method is considered that the diameter DN/ID (Ref. ASTM D2239) has a proportional relation with the extruded helical angle. Thereby the supplementary hoop stress can be expected to increase accordance with diameter. That was why the author evaluated the ring stiffness test from 200 DN/ID to 2000 DN/ID based on SIDR (Standard inside diameter dimension ratio) by random sampling. For the results, minimum diameter described minimum bending modulus according to structural design and helical angle. Besides the author had been done long term creep tests by ISO 1167-1 and -2 with minimum diameter, 200 DN/ID which it was described minimum bending modulus. For the results, σLPL analyzed by ISO 9080 was 21,078 MPa. That mean, lowest MRS value was indicated whole PE-sGF systems of long term property. Reference to ISO 12162, MRS of PE-sGF is 20 MPa, and classification number is 200. (ISO 12162 categorized: PE-sGF 200) For this summary, it should be necessary to develop the new pipeline system with new concept to proceed above constructions against environmental climate change whatever we have never got before. Moreover it can be said that it is an important to provide more safety and secure pipeline system with the long term property. Thatwas why, It was completed to develop the highly performance PE-sGF piping system for soften ground as large diameter piping system.
