Abstract
According to the present invention, there is provided a pipe forming apparatus for forming a pipe at an installation site. The apparatus includes a former upon which material is wound, and a mold for receiving the former bearing the wound material. An applicator is provided for applying curable liquid within the mold. Advantageously, the pipe is formed at site to provide for efficient formation of a pipeline. A transported ISO container providing the material and curable liquid to the site can produce 800 metres of pipeline section, compared with 60 metres in the prior art, representing a significant increase in efficiency.
Claims16
A pipe forming apparatus for forming a pipe at an installation site, said apparatus comprising:
- a holder that holds sheet material;
- a former;
- a racking system for axially advancing the holder relative to the former so that the sheet material is wound around the former to form the pipe with one or more steps at each end of the pipe so that the pipe has two stepped ends, wherein wound material at one end of the pipe forms a complementary fit with the other end;
- a mold for receiving the former bearing the wound sheet material;
- a lock for locking the former to a completed pipe, whilst enabling the former to rotate when winding material for another pipe;
- and
- an applicator for applying curable liquid within the mold.
A method for forming a pipe at an installation site, said method including:
- reducing cross-sectional area of a former;
- winding material upon the former with the reduced cross-sectional area;
- receiving the former bearing the wound material within a mold;
- increasing the cross-sectional area of the former for applying curable liquid within the mold;
- applying the curable liquid within the mold;
- and
- locking the former to a completed pipe with a lock, whilst enabling the former to rotate when winding material for another pipe.
