The combination of a pair of aligned tubular membes joined together in end-to-end relationship, where the tubular members are joined by an internal expansion coupling device. The combination is designed for applications exposed to high operating temperatures and pressures. The combination comprises a tubular member characterized by a flared end portion having a diameter exceeding the diameter of the tubular members. Additionally, there is provided an internal expansion coupling device formed of an elongated open ended tubular joint member consisting of a relatively rigid sheet-like member, where the sheet ends overlap such that the end portions lie essentially contiguous with each other. A compressive seal member is provided between said end portions, and a flexible O-ring type member formed of a high temperature resistant material, is disposed within said flared end portion in contact with the relatively rigid sheet-like member. Finally, means are provided for expanding said sheet-like member whereby said sheet ends may be caused to move circumferentially towards one another to compress said seal member and to urge said O-ring type member against the flared end portion to secure and seal said aligned tubular members.
