DTH drill pipes play a significant role in all DTH drilling, regardless of application, rock type, hole depth or drill rig. The key features of a high quality DTH tube are durability, accuracy and manageability.
DTH drill rods transmit compressed air, so as to power the hammers to perform drilling work. Sinodrills DTH drill pipes are made of superior alloy, and both thread ends are friction welded to the seamless steel pipe. The high-pressure air is delivered to the DTH hammer by the DTH drill pipe, and simultaneously, it transfers the rotation and press force to the DTH hammer.
• 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.
Mining, quarrying, water well drilling, geothermal well drilling, and foundation piling are crucial industrial operations. Mining extracts minerals and ores from the earth, while quarrying focuses on extracting stones and aggregates for construction. Water well drilling provides essential water resources for domestic and industrial use. Geothermal well drilling harnesses the Earth’s heat for renewable energy. Foundation piling strengthens construction foundations by driving piles into the ground. These activities require specialized equipment and expertise to ensure safety and efficiency, playing vital roles in various sectors like energy, construction, and resource development.
