I
t happened that in 1994, Massimo Colli, who was only
22 at the time, came to me and said,‘Renzo, my father
tells me he wants to produce drill pipes,could you give
me a hand?’” In this way, Renzo Chirulli, now USA
export manager for the Colli Drill Co., recounts the begin-
ning of the adventure that has grown this business, in just
more than 12 years, into one of the leading world produc-
ers of HDD and waterwell drill pipes.
“Between 1994 and 1995,”says Chirulli,“I couldn’t tell you
how many kilometers Massimo [Colli] and myself traveled all
over Europe,looking for machinery and steel.We went around
with an aged laptop,a copy of the Stahlschlussel (key to steel)
and a tape of Laura Pausini to feel nearer to home even in the
most out of the way villages in Germany and England.”
Since then,growth has been really heady.The Colli Group
now numbers nine companies,spread over three continents,
with about 100 employees and an overall turnover of more
than $25 million. Drill pipe production began toward the
end of 1995,and to date more than 220,000 drill pipes have
been manufactured,their diameters varying between 38 and
220 mm (1.5 to 8.7 in.) and lengths of up to 12 m (40 ft).
“At the start, few took us seriously,” says Massimo Colli,
general manager of Colli Drill.“My father would see red,
speaking of the tons of steel we had used to try out friction
welding,before beginning the actual production.Currently
we have customers in at least 30 different countries — from
South America to Far East Asia. Our main objective has
always been exclusively to give our customers complete
satisfaction, at the risk of not earning a cent.”
For this reason,investment in research and development
has always been the focal point of Colli Drill’s entire activ-
ity. “We began with a portable Rockwell durometer, but
today we can boast of two internal laboratories entirely
given over to metallographic and mechanical tests on both
steel and welding,”says Chirulli,who was production man-
ager for Colli Drill in 1995.The HDD drill rods produced
by Colli Drill today are of three main types — standard
friction welded (SFW),forged one-piece (FOP) and forged-
friction welded (FFW) drill pipes.
At Colli Drill,all manufacturing processes are monitored
by cutting-edge sensors, as well as computerized systems.
“Every single steel batch that enters our production
process is given an identifying tag number, which enables
us to trace back the original cast, the characteristics
declared by the steel producer and those determined
directly by ourselves in our laboratories when the steel
arrives at the factory,” says Mirko Samac, mechanical engi-
neer and the current production manager of Colli Drill.
“When it leaves our plants, each Colli Drill pipe is brand-
ed with two numbers, one for each welding, resulting in
what can be called an identity card.”
For each welding process, in fact, more than 700 pieces
of data are recorded, which means that the entire produc-
tion history of every single steel item that leaves the prem-
ises can be traced back.
“Should a rod break, we can tell at once whether the
break depends on incorrect use of the pipe in the jobsite,
or may be due to a defect in the material or manufacturing

process,” says Samac. “Over the last six years, we have
recorded an average of one break every 3,000 pipes pro-
duced.In 90 percent of the cases,the break was caused by
incorrect use in the jobsite, while in the remaining cases
— we are speaking here, therefore, of less than one pipe
every 30,000 — it was due to a defect in the material or a
production problem.”
“When this happens”explains Genni Colli,marketing,sales
and development manager,“we have always substituted the
damaged parts,and always found satisfactory agreements with
our customers,our reward being their continuing fidelity.”
Genni Colli,Massimo Colli’s sister,has a degree in chemistry,
and joined the company in 2001.She is firmly convinced that
the quality of the product is the strong point of the Colli Drill
pipes.“We don’t go for spinning tales to our customers,”says
Genni Colli.“We prefer that the reality we express with our
products be founded on the exceptional quality of the prod-
uct and on the entire satisfaction of our customers.”
Since 1998,Colli Drill has been certified ISO 9001 for the
production and sale of drill pipes,but the quality of the prod-
uct,those in the company insist,is not based on certificates.
“We have the greatest respect for our competitors,but we
have never believed that competition, especially for HDD
drill pipes, should be founded solely on price,” says Genni
Colli.“And for this reason,we continue to invest in research
and technology. Drilling rods are not simple steel pieces,
and in ours, the technological content is of the highest.”
Some months ago, Chirulli undertook the appointment
as Colli Drill’s USA export manager, with a view to bring-
ing Colli Drill pipes to American customers. “I love
America, its people, its great spaces and its work style. But
our biggest competitor today is the dollar,” he says.
“However, we are used to sacrifices, and we’ll win this
challenge too. We’ll bring Colli Drill quality from Italy to
our American customers,even if we’ve got to swim there.”

Circle 41 on reader service card.
Chirulli, who is 42 years old and an engineer who spe-
cialized in directional drilling and trenchless technology,
knows HDD well, as he has produced rigs and has carried
out hundreds of kilometers of HDD installations. He has
made a name for himself in the international no-dig tech-
nical-scientific community and has written books and arti-
cles on this subject.He sees Colli Drill as a family-run com-
pany and is convinced that the American market, as hap-
pened with other markets spread throughout the world,is
ready for Colli Drill pipes.
“When we began production of forged-one-piece (FOP)
drill pipes toward the end of 2006,we rendered our range
of offers for HDD pipes complete,” says Genni Colli.“We
did this to meet the needs of customers accustomed to
using FOP type pipes, but we are convinced that the top
technology for a HDD drilling pipe is the forged-friction-
welded drill pipes.”
Colli Drill’s research on forged-friction-welded pipes for
HDD started in 2000, and the first forged-friction-welded
pipe was produced in 2001.Why are people in Colli Drill
so sure the FFW pipes are the best?
“Because in an FFW pipe we can use differentiated
steels, for the pipe and the tool joints, with the highest
mechanical characteristics, being able to carry out special
treatments on the threads which are impossible on forged-
one-piece pipes,” says Massimo Colli.
“Besides, from a hydraulic point of view and therefore
involving efficiency in transporting drilling fluids,” adds
Chirulli,“an FFW type is decidedly better than the FOP sort.”
In fact,that the characteristics of the steels used in Colli
Drill for the production of drill pipes for HDD are of the
highest grade, company officials say. The pipes are pro-
duced and sold with nominal characteristics that meet the
API grade S135 (minimum yield strength of the steel =
135.000 psi), but the true yield strength of the steels used
is more than 170,000 psi.
Why use such high characteristics?
“Because when you are pulling back a pipe,perhaps over
a river crossing, the last thing in the world you want is for
the drill pipe to break. Nobody, therefore, stoops to com-
promise with regard to quality in Colli Drill,”says Chirulli.
“If we want to lead the field,we’ve got to think and act like
leaders,” says Massimo Colli.“And for the last 12 years,we
never stopped doing just that.”
The challenge is on.Already various producers of HDD
rigs are today purchasing pipes produced by Colli Drill. In
some countries, the company sells through national deal-
ers,in others directly to the end customer.Colli Drill takes
part in the main international fairs of the drilling sector
and, in 2007, will be present at BAUMA 2007 (April 23-29)
in Munich; No-Dig Roma07 Mediterranean — XXV
International (Sept. 10-12 in Rome) and ICUEE (Oct. 16-18
in Louisville, Ky.).
