A plastic pressure vessel comprises a first (1, 2) and a second part (2, 1) welded to each other. The first part (1) comprises a layer (11) of thermoplastic material having substantially continuous fibres. The second part comprises a layered structure having an first (20) and a second (22) layer of thermoplastic material having substantially continuous fibres separated by a central (21) layer comprising thermoplastic material. The layer having substantially continuous fibres (11) of the first part extends over a length (d) sandwiched in between and connected with the first (20) and second (22) layer of thermoplastic material having substantial continuous fibres of the second part. Preferably the second part is provided with a slit (24) and the first part with a fitting protrusion, preferably with a bevelled end (23).
Plastic pressure vessel for a fluid comprising a first and a second part connected to each other, one of the first and second part being a main body or an end part, characterized in that the first part comprises at least one layer of thermoplastic material having substantially continuous fibres, and the second part comprises a layered structure having a first and a second layer of thermoplastic material, at least one of said first and second layers having substantially continuous fibres, said first and second layers being separated by a inner plastic layer, the layer having substantially continuous fibres of the first part extending over a length (d) sandwiched in between and connected with the first and second layer of thermoplastic material of the second part.
