Product Description

Various Wall Thickness Drill Steel Pipe for DTH Drilling

DTH pipe/rod
DTH drill tubes are used for connecting DTH hammer and DTH button bits; they are made from seamless tubes. Tubes play a significant role in all DTH drilling, regardless of application, rock type, hole depth or drill rig.
 
Features:
 
DTH Drill rod is made of high quality material detected by spectrograph, impact and tension test.
With fully digitized processing line introduced from Japan with integral heat treatment equipment
Anti adhesion thread with nitrogen treatment on surface make it easier for handling.
Metallography detection, hardness test, magnaflux inspection, ultrasonic flaw detection, tensile test and impact test ensure products quality.
The key features of a high quality. DTH tube are durability, accuracy and manageability.
 
Advantage:
 
1.applicable hard, very hard and medium soft rock formations.
2.Reliable quality, long service life, rare abnormal breakage during service life.
3.Good flushing effect to ensure high drilling rate
4.Strict quality warranty and compensation rules
 
According to different application, different diameters of drill tubes are needed, basically, smaller DTH hammers need smaller DTH drill tubes, vice versa.
Usually we are offering 50mm, 60mm, 76mm, 89mm, etc.
Our all DTH drill tubes are friction welded, and usually the threads are standard API connections, like 2 3/8" API REG thread, 3 1/2" API REG thread or API IF thread, etc. According to customers request, from 1000mm to 5000mm length of tubes are available.
 
Technical data:
 
Length: 1, 000mm ~ 9, 000mm;
Diameter: 76mm (3") ~ 146mm (5-3/4");
Wall Thickness: 5.5mm ~ 8mm;
Connection Thread: 2 3/8", 2-7/8", 3-1/2", 4 1/2" API Reg. Or API IF Thread.
