Drill Pipe
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.
Casing Pipe
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.
API SPEC 5CT、J55
Pup Joints are used to adjust the height of full length tubing or casing strings. They are also used to adjust the depth of downhole tools.HengAn Weiye can customize any length of the pup joint as our customer required.Pup Joints are a mandatory part of equipment in almost any well. Due to their shorter length, they are typically easier to handle and to use. At the same time, they provide the same performance as the tubing/casing/drill pipe that they are attached to.

API Tubing
Tubing is a relatively small-diameter pipe that is run into a well to serve as a conduit for the passage of oil and gas to the field surface facilities for processing. Tubing must be adequately strong to resist loads and deformations associated with production and work overs. Further, tubing must be sized to support the expected rates of production of oil and gas.
