Product Details

Description

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 the standard drill pipe to reduce fatigue failures. In other applications, the HWDP is used as an additional weight to weigh down the drill string.

Heavy-weight drill pipe is a medium-weight drilling pipe, (referred to standards in API SPEC 7-1). It has a bigger wall thickness than a common drilling pipe and is smaller than a drill collar.

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:2-3/8" to 7-5/8" OD, Range 2 and 3

Heavy Weight pipe:2-3/8" to 6-5/8" OD, Range 2 and 3

Drill Collars:2-7/8" to 14"

Grades: E75, X95, G105, S135

Connection threads:NC26, NC31, NC38, NC40, NC46, NC50, 5 1/2FH.6 5/8FH.

Internal Upset: IU, EU, IEU

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.
