Abstract
Appts. for casting metal pipes of the generally known type comprising a rotatable mould with an elongated internal cavity, provided with means for releasably fixing a core to one and so that it can be enclosed within the cavity, with the improvement whereby a repeatedly usable metal core is provided, with one end fitting into the mould cavity so that the metal cast in this comes into contact with this end and is retained in the cavity while it solidifies.
