Abstract: A liner assembly includes a first ring member, a second ring member, a corrosion barrier ring, a first liner, and a second liner. The first ring member includes a body member having a first end and a second end. The first end has a flange extending substantially perpendicularly therefrom. The second ring member includes a body member having a first end and a second end. The second end has a flange extending substantially perpendicularly therefrom. The body member of the first ring member extends along a face of the first liner a first distance beyond an inner diameter of the first liner. The body member of the second ring member extends along a face of the second liner a second distance beyond an inner diameter of the second liner.

Abstract: A coupling assembly includes a first pipe having a threaded portion and a non-threaded portion and a second pipe having a threaded and non-threaded portion. The non-threaded portion of each of the pipes is located at a free end of the first pipe and the second pipe. The coupling assembly also includes a coupling member for fixedly connecting the first pipe and the second pipe. The coupling member includes a first threaded inlet for receiving the first pipe, a second threaded inlet for receiving the second pipe and a non-threaded portion extending between the first inlet and the second inlet. The non-threaded portion of the coupling member includes an annular recess. A cross-section of the annular recess includes a vertical leg, a first angled leg extending from the vertical leg, a horizontal leg extending from the first angled leg, a second angled leg extending from the horizontal leg and a third angled leg extending from the second angled leg to the first threaded inlet of the coupling member.

Abstract: A liner assembly including a first ring member, a second ring member, a corrosion barrier ring, a first liner and a second liner. The first ring member has a body member with a first end and a second end. The first end has a first flange and a second flange extending therefrom. The first flange and the second flange define a space therebetween. The second ring member has an extended body member having a first end and a second end. The second end has a first flange and a second flange extending therefrom. The first flange and the second flange define a space therebetween. The corrosion barrier ring is disposed between and cooperates with the first end of the first ring member and the second end of the second ring member. The first liner is configured to be secured in the space formed between the first flange and the second flange of the first ring member. The second liner is configured to be secured in the space formed between the first flange and the second flange of the second ring member.
