Product Name: Bestlink Factory Drilling Tools Steel Pipe for DTH Model NO.: 76 mm Material: Carbon Steel Usage: Well Drilling Length: 1m - 6m Certification: ISO9001 Process Type: Forging Wall Thickness: 5.5-8mm Machine Type: Drilling Tools Application: Quarry, Mining and Civil Construction Diameter: 76mm (3") ~ 146mm (5-3/4"); Trademark: BESTlink Transport Package: Nude Packing Specification: ISO Origin: Xiamen, China HS Code: 72288000 Product Description Bestlink Factory Drilling Tools Steel Pipe for DTHDTH pipe/rodDTH 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 equipmentAnti 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 rate4.Strict quality warranty and compensation rulesAccording 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.Ourall 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.
