Abstract: The invention concerns a method of producing various massive blanks of encapsulated pipe connections by pressure moulding metal powder material, such as an encapsulated manifold (1) on a base plate (2). In an open mould of steel plates are installed a planned network of both curved and straight pipes (4) both for fluids, via a series of control valves (3) to a control module for hydraulic couplings, and for through pipes (5) for couplings for hydraulic and electrical distribution. From holes in the mould walls pipe ends are extending, which are sealed to the holes in the mould plates. External plates entered on to pipe connectors and locked before the HIP process hold the geometry of the piping network. When the network of pipe and cable connections is estab¬ lished, the top plate is sealed to the mould. A flexible steel bellows is fastened to the top plate, and is used to fill the mould with casting powder and for replenishing to eliminate volumetric shrinkage in the mould during the HIP process, whereafter the mould is removed, and the cast blank is machined before external pipe network and cable connections are connected.
