  • first liner 15' with an adhesive or first liner 15' may be friction fit within annular gap 87 formed between outer sleeve 83 and flange 99 of inner sleeve 85.
  • Liner assembly 3' also includes a second ring member 51' configured to securely engage second liner 19' at first end 13' of second pipe segment 7'.
  • Second ring member 51' is identical to second ring member 51' discussed hereinabove with regard to the first embodiment of the present invention.
  • a corrosion barrier ring 75* disposed between inner sleeve 85 and second ring member 51 ' is also provided.
  • Corrosion barrier ring 75' is identical to corrosion barrier ring 75 discussed hereinabove with regard to the first embodiment of the present invention.
  • Liner assembly 3' in accordance with the second embodiment of the present invention is installed within a pipeline as follows. First, second ring member 51' is submersed in acetone to ensure that it is adequately cleaned. In addition, the inner diameter of second liner 19' is cleaned with acetone. Next, after the acetone has total evaporated, an adhesive is applied to the space between the first flange and the second flange of the second ring member 51'. Thereafter, second liner 19' is positioned within the space between the first flange and the second flange of second ring member 51' using a clockwise rotational motion. All excessive adhesive is then cleaned away from the second liner 19* and the second ring member 51' and the adhesive is allowed to cure for at least 60 minutes.
  • a setting plug (not shown) is installed in a first end of second ring member 51'.
  • the liner is then inserted into first end 23' of coupling member 9' and then into second pipe segment T, which has been secured to coupling member 9', such that the second ring member is properly positioned within coupling member 9* as shown in FIG. 7.
  • a pumping cap is positioned at a second end of second pipe segment 7' over second liner 19'.
  • Mortar is then pumped through the pumping cap to fill second annular gap 21'.
  • the mortar is then allowed to set for about 2 to 3 hours before the pumping cap is removed.
  • first liner 15' is positioned within first pipe segment 5' and mortar is pumped into first annular gap 17' using the pumping cap.
  • Outer sleeve 83 of two-part ring member 81 is positioned over the outer diameter of first liner 15', and then positioned within second end II 1 of first pipe segment 5' using a sleeve tool (not shown).
  • second end 11' of first pipe segment 5' with outer sleeve 83 positioned therein is prepared for installation of inner sleeve 85.
  • the inner diameter of first liner 15' and inner sleeve 85 are cleaned with acetone.

Abstract

L'invention concerne un ensemble de revêtement comprenant un premier élément annulaire, un second élément annulaire, un anneau de protection contre la corrosion, un premier revêtement et un second revêtement. Le premier élément annulaire comprend un élément de corps doté d'une première extrémité et d'une seconde extrémité. La première extrémité comprend un premier rebord et un second rebord s'étendant depuis celle-ci. Le premier rebord et le second rebord définissent un espace entre eux. Le second élément annulaire comprend un élément de corps étendu doté d'une première extrémité et d'une seconde extrémité. La seconde extrémité comprend un premier rebord et un second rebord s'étendant depuis celle-ci. Le premier rebord et le second rebord définissent un espace entre eux. L'anneau de protection contre la corrosion est disposé entre la première extrémité du premier élément annulaire et la seconde extrémité du second élément annulaire et coopère avec celles-ci.
