key features of a high quality DTH tube are durability, accuracy
and manageability.
Description
Drill Pipe Schramm Style and Schramm T46 Sytle DTH Drill Pipes
DTH drill pipes transmit compressed air, so as to power the hammers
to perform drilling works. ROSCHEN Drill DTH drill pipes are made
of superior alloy and the both thread ends are friction welded to
the seamless steel pipe.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.
Features:
• Complete sizes for the option, suitable for different types of
DTH drilling systems;
• The rods are made of cold-drawn steel with high manufacturing
precision;
• Thread joint sturdily linked to the rod via friction welding;
• Nitriding process grants the thread joint good hardness, good
wear quality and thus long lifespan.
Applications
Mining, quarrying, water well drilling, geothermal well drilling,
foundation piling, etc.
