Supporting system for superisolation in annular gap between flexible corrugated pipes has cylindrical rod frames between superisolation and inner and outer corrugated pipes

摘要

The system has a cylindrical frame made of rods (1) distributed about the periphery and fixed to rings (2) alternately on the inside and outside. The frame is mounted between the superisolation (3) and the inner corrugated pipe (5). Another rod frame is mounted between the superisolation and the outer corrugated pipe (4).
