Liaocheng Zeyu Metal Products Co., Ltd. (www.zk55simnmo.com) is located in Liaocheng, Shandong Liaocheng Development Zone Industrial Park, Contact: Mr. Sun Metal Products Co., Ltd. Liaocheng Zeyu www.40simncrnimo.com geological spiral drill that I company on the basis of geological drill high-torque performance on single or double helical blade helical blade, the prestressed winding process machining and welding. Geological club auger body made of high quality geological special alloy steel pipe, drill pipe joints made of high quality alloy steel, tempered by the true air conditioning, greatly improving the fatigue strength and shear strength. Geological spiral drill pipe friction welding using advanced production technology, with high flexural strength drill, welding firm characteristics. Full use of advanced production equipment, CNC machining equipment, high production efficiency, quality and stability characteristics. To ensure the requirements of straightness deep hole drilling. Ultra-helix spiral blade design makes Geological spiral drill with a torque, slagging speed, good drilling molding, easy sticking through the water feature is particularly suitable for the bad effects of soft coal slag and coal and rock deep class hole drilling. Diameter Φ73 following geological spiral drill pipe, with a variety of full hydraulic drilling rig directly supporting the use of the direct use of the rig were cylindrical clamp screw drill drill drill and replace triangular drill, convenient, greatly reducing operator labor intensity. Drilling in the ultra-high pressure soft seam conditions, the use of construction techniques when drilling units, the choice of a diameter of 90 square drill pipe, drill pipe 113,133,146 large spiral geology, convenient installation to achieve the core pipe laying. Geological spiral drill for drilling deep mine efficiently provide a guarantee to fill the gap. Liaocheng Zeyu Metal Products Co., Tri-arc ridge-type gas drainage drill pipe, drill pipe referred to [Tri], divided into triangular arc cone drill screw-type, high-pressure sealed in accordance with the joint connecting thread form and Tri-plug type. Tri drill made of high quality carbon steel pipe for drilling levers body joints at both ends using high quality materials 42Crmo drill pipe, high pressure molding processing, real air conditioning and tempering. Adopt international advanced interference welding assembly process, to avoid quality problems because they can not use the friction caused by the welding process of welding, compared with similar products greatly improve the mechanical properties of the product and the ability to adapt to the complex geological conditions of deep hole drilling. Tri drill has become the preferred type and soft coal seam drilling of deep geological conditions under soft.
