Upset Pipe

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).

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.

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.
