Drill pipe is 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.

Internal Upset: IU, EU, IEU

Heavy weight drill pipe is a medium-weight drilling pipe, (referred standards in API SPEC 7-1). It has bigger wall thickness than common drilling pipe and smaller than drill collar.

API SPEC 5DP specifies the technical delivery conditions for steel drill-pipes with upset pipe-body ends and weld-on tool joints for use in drilling and production operations in petroleum and natural gas industries for three product specification .

levels (PSL-1,PSL-2 and PSL-3).PS-1 specifies wall thickness, impact strength, and yield strength requirements specific to the material grade.Specification levels PL-2/PL-3 have additional mandatory requirements.

There are probably hundreds of different methods for packing a pipe, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security.

● Plastic caps plugged at the two sides of pipe ends

● Should be avoided by the steel strapping and transport damage

● Bundled signs should be uniform and consistent

● The same bundle(batch) of steel pipe should be came from the same furnace.

● The steel pipe has the same furnace number, the same steel grade, the same specifications.

Our packing can meet any needs of the customers.
