Description
DTH drill pipes deliver compressed air to power down-the-hole hammers during drilling work.
Manufactured from cold-drawn alloy steel, they adopt friction welding to connect pipe body and joints.
Nitrided API threads offer strong wear resistance and long service life for mining, water well and geothermal drilling.
Features
- Complete sizes for option, suitable for different types of DTH drilling system;
- 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 wearing quality and thus long lifespan.
Applications
Mining, quarrying, water well drilling, geothermal well drilling, foundation piling, etc.
