Abstract
The invention is directed toward a T-pipe designed for transfer of high pressure fluids through the main run and where the branch run is left in a standby position for possible use in the future. The opening, or outlet, of the branch run is sealed by a material continuous with the main run. An opening and fluid flow in the branch run while the main run is in production and remains under full pressure, is to be provided. The sealing includes a metal membrane which is in contact with the fluid flowing in the main run. The metal membrane is thinner than the wall thickness of the T-pipe and is supported by a plug inserted in the branch run.
