Colli Drill produces a wide range of drill pipes for a variety of uses such as vertical drilling, water wells and directional drilling. Our production boasts the most cutting edge technology available today, and this makes it possible for us to produce drill pipes with top notch materials. We started producing drill pipes towards the end of 1995 and so far have turned out over 220,000 rods with diameters ranging between 38 mm (1,5 in.) and 220 mm (8,7 in.), and lengths of up to 12 metres (40 ft.).
The most cutting edge production technology available today is centred in two different production plants. In the field of directional drilling pipes, our offer not only includes the traditional types of product, such as Standard Friction Welded (SFW) and Forged-One-Piece (FOP), but also, since 2001, the Forged-Friction Welded (FFW) which represents the highest peak from the point of view of technology and on-the-spot performance.
