Abstract
A pipeline system is enclosed including unlined or plastic lined pipes. A mechanical metal to metal connection is employed that can provide a fluid tight seal. A pipe coupling may be employed to span the connection. Plastic lined pipes can have their plastic liners connected to form a fluid tight bladder. Electro-fusion may be employed.
