High Strength Alloyd Horizontal directional drilling pipe tooling for HDD machine

Charater of drilling pipe

the features of a high quality HDT pipe are durability, accuracy and manage ability. these 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 durabilityand 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, standard API threads will be the best choice. SANSUNG 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.
