DTH drill pipe

Key features of a high quality DTH pipe are durability, accuracy and manageability.

Drill Pipe is a thin-walled, hollow, steel and aluminum alloy piping which is used for drilling and on drilling rigs to facilitate the drilling of a borehole. It comes in a series of sizes, weights and strengths but it is generally 27 to 32 feet long and the longest length ranging around 45 feet. It is hollow inside and thus it allows the drilling fluids to be pumped through it. It is a portion of an overall drill string, which is composed of a both bottom hole assembly and drill pipes that are tubular portions close to the bit.

 

Black Diamond’ s pipes are made from cold drawn piping, providing a superior surface finish and tolerance compared to conventional pipes made from hot rolled piping. This drastically reduces the risk of scaling from the pipes entering the hammer, a major cause of premature hammer failure.

 

The joints are friction welded to achieve maximum strength, and the threads of the end-pieces are heat treated for optimum durability and strength of the thread profile. This not only ensures long thread life, but also makes coupling and uncoupling quick and simple, reducing drilling time.

Pipe diameter should be close to the hammer diameter to provide optimum flushing, reducing the chances of getting stuck. Mostly, the standard API threads is the best choice and widely used. The high pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation and press force to the DTH hammer.
