Spiral drill pipe is our company in the geological drill pipe on the basis of high torque performance, the use of single screw blade or double screw blade, prestressed winding, automatic welding. The drill pipe body is made of high-grade alloy steel pipe for geological drilling, and the drill pipe joint is made of high-quality alloy structural steel, which is formed by high pressure and treated by real air conditioning, and is made by friction welding.
It has the characteristics of high bending strength, solid welding and high slag discharge efficiency. Compared with similar products, the fatigue strength and shear strength are greatly improved. Geological auger is mainly suitable for deep hole drilling construction of medium and hard geological conditions, which greatly improves the production efficiency of drilling construction, and is the first choice for efficient drilling construction and energy saving in coal mines.
• Offshore oil and gas exploitation: In offshore oil and gas exploitation, auger drill pipe is mainly used for drilling and exploitation operations.
• Power line construction: In power line construction, excavators install augers for pole hole operations have significant advantages.
• Bridge construction and high-rise building foundation engineering: Long auger drilling rigs are suitable for all kinds of drilling and grouting projects, especially in bridge construction and high-rise building foundation engineering.
• Agricultural irrigation: Spiral steel pipes are also widely used in agricultural irrigation, as irrigation pipes and drainage pipes to help agricultural production
