Drill Pipe

Drill pipe is a steel tube fitted with threaded ends called tool joints. It connects the rig's surface equipment to the bottom hole assembly (BHA) and the bit, carries drilling fluid to the bit and allows the BHA and bit to be raised, lowered and rotated.

Modern wells are deeper and laterals are longer, so drill pipe must be strong and durable to avoid costly downtime. Longmar supplies drill pipe to API specification in sizes from 2-3/8" to 7-5/8" OD, in all standard weights and grades, including SS-95 and SS-105 grades for sour service applications.
