A drill pipe is a seamless steel pipe that composes around 95% of the length of a drill string. For clarity, a drill string is what is used to actually drill into the ground to extract resources. The drill pipe is hollow, which allows drilling fluid to flow freely throughout the pipe and the pumping process to be completed successfully.

Our factory
Packing
· 1- Plastic caps plugged at the two sides of pipe ends
· 2- Should be avoided by the steel strapping and transport damage
· 3- Bundled signs should be uniform and consistent
· 4- The same bundle(batch) of steel pipe should be came from the same furnace.
· 5- The steel pipe has the same furnace number, the same steel grade, the same specifications.
