QA&QB series products have good performancein accuracy and mechanism. Their structures match withinternational standard in application of less than 1000-meterdrilling. Wireline rods are made of strong and ductile geologicalsteel pipes which are entire-length thermal processed. Thread ofdrill rod is strengthened.
RQ series products aredesigned on basis of QB series. Thread of drill rod select negativeangle to ensure tight connection and prevent drop-out. Compared toQB series, tightness of connection of RQ series is improved. Itsstructure is same as QB.
Q-T series is designed fordeep drill application of no more than 1500 meters. Wireline rodsare made of strong and ductile geological steel pipes which areentire-length thermal processed with its both ends upsized. Threadof drill rod is strengthened.
Q-S series is designed forextra deep drill application of no more than 2500 meters. Wirelinerods are made of strong and ductile geological steel pipes whichare entire-length thermal processed with its both ends upsized.Thread of drill rod is strengthened
