Tree Piping

The term tree piping is used to encompass the requirements for all pipe, fittings or pressure conduits, excluding valves and chokes, from the vertical bores of the tree to the flowline connection(s) leaving the subsea tree. The piping may be used for production, pigging, monitoring, water, gas or chemical injection, service or test of the subsea tree.
