Client: Colli Drill Spa, Rome – ITALY
Year: 1994-2007
What I did: I designed the product (drill pipes) in a wide range of diameters, connection types and lengths, setting-up all the mechanical calculation methods; then I studied the manufacturing process (friction welding, thermo-chemical treatments, post welding heat treatments) and all the control procedures; and finally I designed and supervised the construction of the manufacturing plant. Six year of continuous research, enthusiasm, errors and success, achieving a deep knowledge about the directional drilling process, and steel and metallurgy. We set a new standard reference in the industry of drill pipes for shallow horizontal directional drilling. Some patents and some innovative ideas complete the achievements reached thanks to this collaboration.
