All pipe is manufactured as an integral piece.

:: Traceability
Material and process traceability are maintained for each Heavy Weight Drill Pipe product. The Heavy Weight Drill Pipe is given a permanent identification number through its manufacturing process which is traceable to the original mill testing.

:: Cold Rolling
Drill pipe undergoes cyclic, tensile and compressive stresses during drilling operations. These cyclic stresses are mainly focused on the connection thread roots and can cause pipe failure. This stress is reduced by cold rolling the thread roots on every piece of heavy weight drill pipe.

:: Phosphate Coating
All new threads are hot phosphate coated to aid in reducing galling and adhesion of the thread compound.

:: Stress Relief Features
As needed on connections of NC-38 and up stress relief features on both pin and box connections can be machined.
