OUR DRILL PIPE LASTS LONGER AND DRILLS DEEPER

Optional Upgrades We Recommend Adding To Your Drill Pipe Order to Us

Hardbanding:

Hardbanding is a process in which a wear-resistant alloy is applied to the tool joints of drill pipe or drill collars to prolong the life of a drill string. The most cost-effective way to protect tool joints in drilling applications is to hardband them using

Arnco’s XTs,
Tuffband or
Duraband® NC.

All our drill pipe comes standard with 2-3 inch standard hardbanding to protect your drill pipe.

Internal Plastic Coating:

IPC extends the life of your drill pipe and improve drill string performance in even the most aggressive downhole environments, enduring all temperatures commonly encountered during drilling when circulation is maintained. IPC prevents corrosion, pitting, and associated fatigue that can result in washouts and twist-offs, which shut down drilling operations. Coated pipe also reduces friction, increases hydraulic efficiencies, and helps eliminate the build-up of harmful scale deposits.

To extend the longevity of the drill string, we recommend frequent drill pipe coating evaluations.

MAKE AND BREAK :
We recommend our clients to opt for factory assisted 3-cycle Make & Break conducted to 60%, 80% and 100% of the recommended make up torque for each connection before the tool joints are friction welded to the tubes.

Save your precious rig time by opting for factory assisted “Make and Break” option.

DRILL PIPE LIFE TRACKING

Track the maintainence record and life cycle management of your drill pipe using our RFID system. Connected with cloud, it updates all the data and emails you if any joints require your attention.

WHY US ? AS COMPARED TO ACQUIRING DIRECT

Drill And Complete (D&C) has access to a large inventory of new drill pipe, only purchased from the top A.P.I. certified manufacturers, so you’ll know you’re buying the best quality. We can offer competitive pricing as we deal with a number of manufacturers around the world, not only for your order but collectively for number of our clients. Therefore, the commitment of volumes that we can make to these specialised and high tech mills, is more then what an independent drilling contractor would be able to make. So be sure to contact us for a proposal.

There are several A.P.I. drill pipe manufacturers in the U.S. Two of these companies, Grant Prideco and Vam Omsco, are very large publicly held corporations. The main business model of these two manufacturers is to supply other large, publicly held drilling contractors and rental companies. In addition to the “big two” there are also several independent manufacturers throughout the USA. Independent manufacturers such as Tejas Tubulars usually have more favourable pricing and delivery than their larger counterparts. Some of the large independent manufacturers outside the USA are Hilong (Ex China) and Jindal Drill Pipes (India and USA). Jindal Pipes owns its own supply chain and steel production facilities around the world.

D&C proudly represents some of the USA, China and India based drill pipe manufacturers and their products. When we receive an order from you, we run a techno-commercial analysis to ensure the drill pipe that we secure for you is the most price-effective solution available to suit your condition and location. Having access to a number of manufacturers around the world eliminates long delivery times and makes the logistics of buying new pipe significantly easier.

Types, API Grades and Specialised Proprietary Grades

Standard drill pipes are long tubular sections of pipe that make up the majority of the drill string. They are typically a 31 foot long section of tubular pipe but may be anywhere from 18 to 45 feet in length.

Heavy weight drill pipe (HWDP) is a tubular pipe that adds weight or acts as a transitional piece in the drill string. As a transitional section of the drill string, it is placed between the drill collar and standard drill pipe to reduce fatigue failures. In other applications the HWDP is used as an additional weight to weigh down the drill string.

Drill Collars are a component of the drill string that makes up part of the BHA. They are thicker-walled, heavier, and more rigid than drill pipes and are primarily used to weigh down the drill bit while dampening vibration and impact forces.

Drill Pipe Grades

Drill pipe grades include standard API grades (E-75, X-95, G-105, & S-135), as well as proprietary grades.

API Grade Drill Pipe

API SPEC 5DP specifies the technical delivery conditions for steel drill-pipes with upset pipe-body ends and weld-on tool joints for use in drilling and production operations in petroleum and natural gas industries for three product specification levels (PSL-1, PSL-2 and PSL-3). PS-1 specifies wall thickness, impact strength, and yield strength requirements specific to the material grade. Specification levels PL-2 / PL-3 have additional mandatory requirements.

API Drill Pipe Grade	Minimum Yield Strength (psi)	Minimum Tensile Strength (psi)
E-75	75,000	100,000
X-95	95,000	105,000
G-105	105,000	115,000
S-135	135,000	145,000

Proprietary Grades

Proprietary grades often exceed the specifications set forth by API SPEC 5DP. Their enhanced performance properties are developed for sour service, critical service, and other user-defined requirements.

Sour service grades resist sulphide stress corrosion (SSC). SSC can occur when hydrogen sulfide is present. Ingress of hydrogen coupled with higher stresses, low temperatures, low pH, and high chloride content decreases the ductility of steel grades leaving them susceptible to crack propagation and failure.

Critical service grades resist corrosion when sweet gas or high concentrations of carbon dioxide are present. They are a cost effective alternative that is used in water injection applications.

Length

The drill string is made up of several sections of drill pipe. The term “stand” refers to two or three sections of drill pipe that are fed into the well bore to complete 60 to 90 feet of drilling. Each segment of pipe, referred to as a “single”, is classified by API into three distinct length ranges; R1, R2, and R3.

Range 1 (R1) is shortest in length, more common for sizing production tubing or casing, and ranges from 18 to 22 ft.

Range 2 (R2) is considered the standard length for drill pipe and ranges from 27 to 31 ft.

Range 3 (R3) is common in casing and also deployed in deep water drilling applications. The increased length decreases the number of tool joints in each stand of drill pipe. The fall back being that the load exerted on each tool joint is greater increasing wear and reducing the expected life of the drill pipe. R3 ranges from 38 to 45 ft.
