Description

Drill PipesLong tubular sections of pipe that make up the majority of the drill string. They are usually a section of tubular pipe that is 31 feet long but can be 18 to 45 feet long.

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

Heavy Duty Weight Drill Pipe is a means-weight drill pipe, (referenced standards in API SPECIFICS 7-1). It has a larger wall thickness than a normal drill pipe and smaller than a drill collar.

Drill collars are a component of the drill string, which is part of BHA. They are thicker-walled, heavier, and harder than drill pipes, and are mainly used to weigh down the drill bit while absorbing vibration and impact forces.

Drill Pipe: 2-3/8" to 7-5/8" OD, Range 2 & 3

Heavy Pipe Weight: 2-3/8" to 6-5/8" OD, Range 2 & 3

Drill collars: 2-7/8 to 14 inches

Grades: E75, X95, G105, S135
