Geological steel pipe-entire length thermal treatment, NC lathe with former cutters
wire line drill rods are made of strong and ductile alloy-steel pipe, material 30CrMnSiA which are whole pipe thermal processed heat treatment. Rod threads are formed using former cutters and specially hardened so that their accuracy and mechanism reach advanced world standard.
We will make sure the compositions and specifications match the inspection report form the suppliers.

WL-Rods and W-Casing threads are cut with CNC lathe machines with the best tools available in the market by an experienced crew. After threading, rods are induction hardened to prolong their service time.
Sinocoredrill is one of the few manufacturers that provide this service to their customers.
