Wireline Drill Rods High Precision Good Low Temperature Toughness High Torque Resistance
1. Drill pipes are widely used in mining,geological exploring and all kinds of drilling(water,oil,gas,etc) projects.As a leading drill pipe manufacture,we make all kinds of standards and non-standard drill pipes for our customers. Our drill pipes including steel drill pipe,mining drill pipe,water well drill pipe,oil well drill pipe,API drill pipe,DTH drill rod,wireline drill rod,etc.
2. We only choose the best steel tubes in the market to manufacture our rods and pipes. Spot check will be conducted after the steel tubes delivered to company. We will make sure the compositions and specifications match the inspection report form the suppliers.
