Split fittings for use in the installation of a semi-rigid secondary pipe over a primary pipe comprise a pair of housing halves which, when mated, form a housing enclosure, sealing means and clamping means capable of holding the secondary pipe and housing halves as a sealed enclosure. A method of fitting a rigid pipeline system with secondary containment system with a secondary semi-rigid pipe uses the split fittings.

A method of retrofitting a primary pipeline system having at least one junction to provide secondary containment, comprising the steps of: (a) disconnecting a portion of the primary pipeline; (b) sliding a semi-rigid pipeline over said disconnected primary pipeline; (c) sliding the secondary semi-rigid pipeline over another section of an adjoining primary pipeline section; (d) positioning a split fitting over the same or a second junction for said secondary semi-rigid pipeline sections, said split fittings comprised of (i) a pair of housing halves such that when mated and secured together a complete housing enclosure is formed which has at least two extremities with openings through which the primary pipeline passes, and said housing enclosure being capable of enclosing a portion of the pipeline and capable of having the secondary pipeline held to the extremities by clamping means, (ii) sealing means positioned on each mated surface to form a liquid tight seal between the housing halves, and (iii) a clamping means; (e) mating said housing halve to form a housing enclosure; (f) attaching said semi-rigid pipeline sections to the housing enclosure; (g) clamping the secondary semi-rigid pipeline sections to the housing enclosure with a clamping means to form a liquid tight seal; (h) reconnecting the disconnected portion of the primary pipeline to the junction; and (i) attaching ends of said secondary pipeline sections to form a closed space providing the secondary containment.
