BESTLINK API Down The Hole Drilling DTH drill steel pipes for rock drilling and well drilling

DTH drill pipe

Key features of a high quality DTH pipe are durability, accuracy and manage ability. BESTLINK'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.  

In most applications, BESTLINK standard API threads will be the best choice. BESTLINK also offers a wide range of subs and crossover subs to meet an array of demands, all manufactured to the same standards as the pipes.

 

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.

Diameter: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm, 152mm
