Development of novel adhesive agent for hybrid resin pipe

摘要

In the development of FRP OCTG at high temperature and high pressure areas, i.e., for over 5,000 meter class deep well or for EOR (Enhanced Oil Recovery), adhesive agent durable to high temperature and designed pressure is strongly required. In this paper, we have newly developed adhesive agent for the bonding of the joint part of FRP pipe under 150℃ level of high temperature, and confirmed that it fulfilled strength retention of GPI Standards (above 80%). Furthermore, we have evaluated the adhesive performance by, simplified tensile test and compared with commercially available adhesives.
