Super 13 Chromes offer improved mechanical properties and increased resistance to the effects of CO2 , H2S, chlorides, pH, and temperatures when compared with standard 13 Chrome. The higher strength and temperature resistance, relative to 13 Chrome L80, allow their use in deeper wells with high pressure and high temperature (HPHT) conditions, as downhole tubular components, packers, and other subsurface equipment. Super 13 Chromes also provide increased resistance to H2S and chlorides relative to Modified 13 Chrome, allowing for use in mild sour environments.

API 5DP drill pipe is a kind of steel pipe with screw thread in the pipe end. It is used for connecting ground rig equipment and drill grinding equipment at the bottom of drilling wells. The main purpose of drill pipes is to transport drilling mud to the drill bit. It rises up, lowers and rotates together with the drill bit. Its strength must withstand the pressure, torque, vibration and other forces caused by the drill hole. In the oil and gas exploration and refining process, API 5DP drill pipe can be used for multiple times. Shunfu provides a number of drill pipes available in various sizes and weights to meet the drilling needs of companies in the oil and gas industry.

API 5DP Drill pipe is composed of pipe body and tool joint by welded together. It is used to connect drilling rig surface equipment and bottom equipment or bottom hole equipment. Furthermore, drilling pipe can bear heavy pressure from internal and external, twist, bend and vibration which can be used more than one time during oil or gas production.

Drill pipe is a heavy, seamless tube can rotate the drill bit and circulates drilling fluid. It allows the drilling fluid to be pumped through the bit and back up the annulus. The pipe is subject to axial tension, extremely high torque and high internal pressure.

Drill Pipe is durable steel pipe used in drilling activities, standards in API 5DP and API SPEC 7-1.

Drill pipe is an important components for drilling rig to extract oil or other liquids from down ground. It is not used for extraction, instead, the hollow tubes pump drilling fluids downward to the bit and back out again as needed to reduce friction and heat buildup. Drill pipe transferred drilling torque to drill bit for drilling under the oil well. It bears complicated strength subject to pulling, loading, pressing, torsion and bending.

Drill pipe is hollow, thick-walled piping that transmits drilling fluid and torque through the wellbore to the drill bit on a drilling rig. It is manufactured to withstand severe internal and external pressure, distortion, bending, and vibration as it both rotates and lifts the bottom hole assembly (BHA). Drill pipe is threaded on each end in a section of pipe referred to as the tool joint. It is manufactured, sampled, tested, and inspected in accordance with standard specifications such as the American Petroleum Institute (API).

Types
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.

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.

Sizing
Drill pipe is manufactured according to standard specifications and is offered in nominal sizes. The two most important dimensional specifications are length and diameter.

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.

Diameter
The outer diameter (OD) of the drill pipe is offered in nominal sizes ranging from 2 3/8" to 6 5/8". The diameter of pipe is selected based on the borehole diameter. In order to effectively circulate drilling mud and minimize pressure losses, the ratio of drill pipe outside diameter to borehole diameter should be about 0.6.

Tool Joint

Each end of the pipe incorporates a tool joint, and is differentiated by the male threaded connection referred to as the "pin" and the female threaded connection which is referred to as the "box". They are pre-fabricated and welded onto the pipe. The tool joints provide high-strength, threaded connections. They are heat treated to a higher strength than the steel of the tube body in order to survive the rigors of drilling and numerous cycles of tightening and loosening of threads. Tool joints are specified by upset and thread type.

Upset

The upset (thread-end finish) refers to the wall of the tool joint at the threaded connection. Drill pipe is offered with an internal upset (IU), an external upset (EU), or an internal-external upset (IEU).

Functions of Drill Pipe
API 5DP drill pipe is mainly applied in oil and gas exploration and development, such as in the construction of deep wells, horizontal wells and large-displacement wells. Its main functions are as follows:
Drill pipes deliver torque and drive the drill bit to drill wells.
Exert pressure that can break the rock at the bottom of well on the drill bit.
API 5DP drill pipe transmits flushing fluid. Through the ground high-pressure slush pump or mud pump, drill mud enters into the inner hole of drill string, flows into the bottom of well to wash rock debris and to cool down the drill bit, passes through the annular space between the drill string outer surface and well wall (carrying rock debris), returns to the ground.

How to Work with Drilling Pipe
The drilling tool is connected drill rod for transferring power. The drill string is usually part are: drill, drill collars, drilling pipe, stabilizers, special connectors and Kelly. The basic role of the drill string are: (1)control the drill bit; (2) imposed WOB; (3) transmission of power; (4) transporting drilling fluid; (5) special operations: extrusion of cement, handling underground accidents.
Drilling pipe is trailing with screw thread for connecting the drilling rig located at the bottom of surface drilling equipment and mill equipment or bottom outlet device. The purpose is to drill the drilling mud delivered to the drill bit, and drill with the increase, decrease or rotating bottom outlet means. Drill pipes must be able to withstand great external pressure, twisting, bending and vibration. In the mining and oil and gas refining process, the drill pipe can be used multiple times.

IU - In an internal upset increased thickness along the inside walls compensate for the metal removed in threading with a uniform, straight outside wall.
EU - In an external upset the increased thickness along the outside diameter of the tubing compensates for the metal removed in threading with a straight bore.
IEU - In an internal-external upset thickness is increased along both the inside and outside walls of the pipe to compensate for the metal removed in threading.

Threaded Connection

Tool joints incorporate threaded connections. They include standard API threads as well as proprietary threads. Each type of threaded connection is specified by threads per inch (TPI) and it's taper. Common API tool joints include regular (REG), full-hole (FH), and internal-flush (IF).
