Drill Pipes

Carlos M. Rosa Lda are produced in high quality steel, with various measures and threads, presenting high durability and strength.

The drill pipes are welded by friction, with this kind of stronger and more consistent welding, ensuring greater longevity to the piece. We also manufacture reverse circulation drill pipes.

Below is some of the possible measures:
