TSC HDD, WHERE UNIQUE PROCESSES ARE ENGINEERED FOR DURABILITY.

TSC HDD pipe starts with proprietary chemistries, requirements for stringently

clean steel, and elements for enhanced fracture toughness that translates into

greater safety margins.

WELDING

TSC HDD utilizes a friction/inertia welding process to weld

the tool joints to the drill pipe body. This process uses a

unique recipe of computer-controlled rotation speed,

pressure changes, and time. When completed, the two

pieces are joined and the finishing process begins. Once

the “rams horn” is machined off, the weld zone is

austenitized then polymer quenched and tempered to

achieve excellent mechanical properties that are verified by

destructive tests. Additional non-destructive inspections

verify the integrity of each weld zone. Then a unique serial number is stamped on the pin to

provide complete traceability. The TSC HDD process consistently produces strong, tough,

and uniform weld properties.

UPSET PROCESS

The unique TSC HDD Upset Process maximizes the length

and uniformity of internal transition zones to provide greater

resistance to stress concentrations. This important quality

feature is accomplished by utilizing the manufacturing

techniques developed over the last 40+ years by TSC Inc.,

the parent company, with TSC HDD’s specialized forging

equipment and uniquely designed tooling.

Consistent long transition area to

maximize the life of Maxi Rig pipe.

HEAT TREAT

All TSC HDD drill pipe tubes are heat treated to the

requirements of API Specification 5DP. TSC HDD’s process

is controlled through computer-monitored precision to

ensure that each and every joint of pipe is treated the same.

INSPECTION

All drill pipe tubes are full length visually inspected, EMI and/

or ultrasonic inspected, and magnetic particle inspected on

both ends before welding on tool joints. TSC HDD also

performs destructive testing on every heat treat order and

every weld order at the frequency required in operating

procedures, API 5DP, and all other applicable specifications.

TOOL JOINTS

Our tool joints are manufactured and heat treated to exceed

API requirements. Threading is done in accordance with

API Specification 7-2. Hardbanding

can be applied to your specification.

Double Shoulder Connection

HEAVY WEIGHT DRILL PIPE FOR HORIZONTAL DIRECTIONAL DRILLING.

HWDP consists of a heavy wall tube with raised central

section. Extra-length tool joints are friction welded on to the

specially machined thick wall tube. HWDP may be included in

the drill string to offer a gradual transition between the bit or

reamer and the flexible drill pipe. This helps prevent

excessive stress concentrations in the drill pipe. In addition,

to extend the fatigue life of the pipe, threads are cold-rolled

and phosphate coated to reduce galling and control

corrosion. All HWDP is manufactured in accordance with

API Specification 7.1.

TSC, Inc. manufactures heavy weight drill pipe (HWDP) in a range of

sizes from 3-1/2” to 6-5/8”.

HDD drill pipe is normally 31.5’ (+/- 6”), unless requested different.

The common thread connections, OD/ID dimensions are listed; however, other dimensions can be provided.

SETTING WORLD RECORDS IN HORIZONTAL DIRECTIONAL DRILLING.

TSC HDD produces 7-5/8” OD drill pipe specifically engineered for the HDD

market. The 7-5/8” drill pipe that was used in the UK to set a world record for

horizontal directional drilling was manufactured at Miller Road #2!

This new, large diameter offers several advantages over conventional sizes of pipe:

It provides a greater stiffness which allows the pipe to be pushed through longer horizontal sections without buckling

It provides the ability to use larger reamers and hole openers

The 4” or larger ID helps in drilling longer sections by increasing fluid volume and flow

The increased cross sectional area provides significant improvements in tensile strength and torsional stiffness
