ChromeMaster System Tongs
for Running CRA Tubulars
The velvet glove approach
Industry experience has taught us that the regular carbon
steel contact and deep penetration into chrome tubulars is
detrimental to the working life of the completion and liners. It
can contaminate the tubular, cause stress fracturing, and lead
to corrosion downhole. By using the same ChromeMaster™
nonferrous tungsten carbide technology on the tongs and
slips, Baker Hughes has one of the most effective systems in
the industry for running CRA tubulars and the only one that
uses the same technology in both tongs and slips.
Central to the ChromeMaster system is the power tong. A
major benefit of the system is flexibility and the ability to be
fitted to conventional open-throat power tongs. BJ Services
uses the ChromeMaster system jaws on 14-, 7 5/8-, 5½- and
4-in. tong models, which accommodate all tubular sizes from
2 3/8 to 14 in.
Unlike other directional needled or toothed handling solutions
on the market, the design provides a superior gripping area
and works efficiently on coated CRA pipe. There is no need for
any mesh inserts or other friction enhancer.

The ChromeMaster system tongs can produce up to 44,000
ft-lb (59,656 N-m) of torque. The rotor and backup on the
ChromeMaster system tong uses a three-jaw, wrap-around
system that maintains the grip on the pipe evenly, eliminating
the chances of ovality occurring. As a result, trouble-free
drift and wireline runs can be made through the bore of the
tubulars. Matching ChromeMaster system jaws are used in the
integrated backups.
If the pipe coating comes off on the ChromeMaster system
jaws, all that is needed is a brush and some rig wash to get
them clean. The jaws can be used for many strings before they
need to be replaced.
The Baker Hughes 14-in. ChromeMaster system tong was
developed to provide nonmarking connection makeup and
breakout on pipe sizes up to 14 in.
In tests for a major oil company, torques up to 42,000 ft-lb
(59,944 N-m) were achieved with the 14-in. ChromeMaster
system tong on 7-in. SM 25/35 CRA pipe. The maximum
penetration of the pipe was .007 in. (0.2 mm). Gripping on
15-in. pipe is also available upon special request.
Leadhand Systems
Baker Hughes’ Leadhand™ systems are today’s safer solution to
manipulating power tongs during casing and tubing operations.
The systems are easy to install and offer improved control over
conventional methods. The systems were developed to create a safer,
less labor intensive way to manipulate hydraulic power tongs. Traditional
methods involve power tongs weighing up to 4,400 lb (1996 kg),
which make them difficult to move, often requiring three crew
members to manipulate.
The Leadhand MK II tong system can dramatically reduce risk of injury,
as well as costs. Consisting of a hydraulically powered articulating arm,
hydraulic supply and remote control panel, the system can be rigged up or
down in only 10 to 15 minutes and requires only one operator to control.
It is effective on floating rigs.
Leadhand MK II system
The tong operator not only controls the movement of the
Leadhand MK II system, but also the lift cylinder for vertical movement.
The operator can open and close the tong doors automatically.
Operated in conjunction with the flush-mounted spider, the whole system
is extremely safe. The tong operator does not need to climb on and off a
work stand, and no other floor hands are needed near the well center.
The Leadhand MK II system is used on conventional rigs where a tugger line
is used to support the weight of the tongs and the hydraulic arm.
A spring hanger or lift cylinder is used with the system. The Leadhand MK II
system arm has a maximum extension of 15 ft (4.6 m). A survey of the rig
floor is necessary before installation.
The Leadhand MK III system is self-supporting and self-propelled. It
moves easily along existing drill floor tracks on the latest generation rigs
to support and propel the tong carriage to and from the well center.
Today’s rig-ups are carried out faster than ever. Our system provides for
automatic compensation for thread makeup.
Compared with other systems, the propulsion system allows the tong
to be moved forward and backward over long distances. In addition,
the tong and carriage may be removed when not in use. It can also be
adapted to remote operation.

Power Tongs for All
Sizes and Applications
Power tongs
Baker Hughes maintains a wide range of casing and
tubing tongs at its service stations around the world. We
aim to meet our customers’ power tong needs, whether
they be for conventional or specialty tongs, such as our
dual completion tongs.
In addition to standard tongs, special power tongs are
also available. For example, the 14-, 7 5/8-, 5½- and
4½-in. power tongs are offered with the complete
ChromeMaster nonmarking jaw system, which is suitable
for sizes through 14 in. Unique tongs are available for
screen liner and drillpipe makeup and breakout.
Baker Hughes offers an array of power tongs with
integrated hydraulic backups to handle tubulars up to
20 in. diameter. These backups provide extra control for
the makeup of premium connections and reduce the
possibility of misalignment.
When using the Leadhand system tong positioning arms,
it is essential to use tongs with hydraulic backups.

Range of Power Tongs for
Special Applications
CRT 350 casing running tool
for makeup of connections
from the topdrive
Baker Hughes offers a range of power tongs for special
applications, some examples of which can be seen below.
Screen liner tongs
In many cases when running gravel pack screens, flush joint
connections are used. This gives an opportunity to shorten the
length of the tong gripping area between the screens. This change
increases the productive area of the screens across the production
zones where long sections of screens are run.
Baker Hughes can greatly increase the efficiency of the production
operations by bringing the tong and backup close together and
using ChromeMaster system dies to provide nonmarking gripping
on CRA pipe.
Baker Hughes also provides special nonmarking handling tools for
running expandable casing, including special false rotary table and
bowls and slips for handling the inner strings.
Tongs for running expandable casing
Expandable casing presents a number of challenges for its makeup
and running. Because the pipe becomes deformed from its original
size, careful handling is required.
Baker Hughes has developed special tongs with a variation of the
ChromeMaster nonmarking gripping system using special dies.
First, the jaws must be able to grip nonconventional diameters.
Second, no deep penetration of the surface of the pipe
should be allowed. The Baker Hughes system fulfills both of
these requirements.
CRT 350 tool
With the CRT 350 casing tool, Baker Hughes offers an alternative
to conventional power tongs for the makeup and breakout
of connections.
Using the power from the topdrive, the CRT 350 tool can, in
addition to make up the connection, provide rotation of the entire
string, circulation through the tool and reciprocation of the string.
This makes it effective when running casing in long-reach or
horizontal wells.
