A system for the moulding of tubular goods, comprising at least one mould having an inner mould part and an outer mould part which together define a mould cavity and an annular pouring gate upwardly, said system additionally comprising a plurality of vibrators and means for lifting the vibrators from and lowering these into the mould cavity through the annular pouring gate. The positioning devices are adapted to displace the vibrators radially with respect to the annular pouring gate, and each of the positioning devices is provided with a separate controlable drive unit which is adapted to displace the vibrators individually. This results in a more flexible system for the moulding of tubular goods which may be adapted to various pipe types, such as egg-shaped, four-sided, circular and other forms.
