HWDP

HWDP - Heavy Weight Drill Pipe

John Lawrie Tubulars offers heavy weight drill pipe from 2⅞” to 6⅝” OD in standard, and spiral designs.

Heavy weight drill pipe (HWDP) is the industry standard for an intermediate weight drill stem member. It reduces the risk of drill pipe fatigue failure by providing a gradual transition in stiffness when HWDP is run above the drill collars.

HWDP uses a unique center upset or wear pad that keeps the tube away from the hole wall, increasing tube life while reducing hole drag and differential sticking problems.

John Lawrie Tubulars offers heavy weight drill pipe from 2⅞” to 6⅝” OD in standard, and spiral designs. We can supply HWDP manufactured using an integral (manufactured from a single bar) or welded (tool joints are welded on) process.
