Product Description


Small hole Tool Steel Drill Rod Drilling Pipe , Consistent concentricity
 
Detailed Product Description
 
NC(NQ) Drill Rod Φ69.9 x 60.3 x 5.2 mm Wireline Drill Rod for drilling rig       
 
ROSCHEN drill rods (NQ DRILL ROD) are all manufactured by CNC machines. They're made of high quality alloy steel with heat-treated. We also can produce various sizes of casing tubes. Our NC & HC (HQ) drill pipe / drill rods has big sharehold in global market.
 
Specifications: 
1. High quality alloy tube
2. Thru-wall heat treated tube body
3. Consistent concentricity, straightness
4. Tapered threads
 
 
Product Advantages:
 
1. Strong and ductile geological steel pipe;
2. Solid quality and considerate service;
3. Cost-effective;
 
 
Raw materials:
 
ROSCHEN 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. 
 
Heat treatment control:
 
Heat treatment will greatly improve the material strength and increase the thread wear life of the rods and casings. We conduct either tru-wall or both ends heat treatment to the tube body. After heat treatment, strength, hardness, straightness and concentricity of the treated tubes will be tested in our lab.
 
Thread opening process:
 
Accuracy of threads will determine the use effects and life time of drill rod and casings.
CNC latches and form cutter are used in thread opening processing to minimize error made by anthropic factors. 
 
Additional thread treatment:
 
Surface of the threads will be cleaned to remove burr adhered after threads are opened.
Afterwards, the tread surface will be phosphated to improve surface conditions.
