114mm Thick Wall Steel Drill Pipes Exploration For Blast Hole, Water Well

114mm Thick Wall Steel Drill Pipes Exploration For Blast Hole, Water Well

Details Description:

Drill pipe is hollow, thick-walled, steel piping that is used on drilling rigs to facilitate the drilling of a wellbore and comes in a variety of sizes, strengths, and weights but are typically 30 to 33 feet in length. They are hollow to allow drilling fluid to be pumped through them, down the hole, and back up the annulus.

It is designed to support its own weight for combined lengths that often exceed 1 mile down into the Earth's crust. Used drill stem is often sent to a yard for inspection, sorted, and stored until new drill sites can be explored. Modified instruments similar to the spherometer are used at inspection sites to identify defects in the metallurgy, in order to prevent fracture of the drill stem during future wellboring.

DTH Drill pipe is made of high quality material detected by spectrograph, impact and tension test.

With fully digitized processing line introduced from Japan with integral heat treatment equipment

Anti adhesion thread with nitrogen treatment on surface make it easier for handling.

Metallography detection, hardness test, magnaflux inspection, ultrasonic flaw detection, tensile test and impact test ensure products quality.
