DRILL ROD




	Drilling is essential to develop underground water and to survey various kinds of geology. So it is very important to choose a drill pipe to connect drilling power to bit. ASAN's Drill Rod joining coupling with friction welding method of accurate size and high strength material, will come true high efficiency and low cost in the drilling industry.

Product Shape	Pipe diameter: 73mm, 88.9mm, 114.3mm, others. Product Length: 3.0M, 4.0M, 4.5M, 6.0M, 7.62M, 8.2M, others.
Product Usage	The main usages are as follows: developing underground water and hot springs, basic ground work, and underground drilling. It also fulfils its function of transmitting rotation power from drilling machine to the bit and supplying high pressure air and water. It can be conneted to the length of tens of meters or thousands of meters.
Product Efficiency	Asan's products are well competent to the world first-class products of Ingersoll-Rand Co.in USA, Atlas Copco Co. in Sweden, Tamrock Co. in Finland, and Furukawa Co. in Japan. Since the establishment of Asan, we have researched and improved our friction welding technology. We are the only specialized company in the field of friction welding in Korea. The products produced by other local companies are only the one jointed connection coupling to the imported seamless pipes. Its strength is weak and its shape is not standardized. Our products meet the international standards and acquired ISO 9002 on October 22, 1997.
