Triangle drill pipe, also known as triangle drill pipe, anti collapse hole drill pipe, anti lock drill pipe.
triangular drill pipeAlso known as triangle drill pipe, anti-collapse hole drill pipe, anti-lock drill pipe.
Triangular drill pipe is a drill pipe for coal mine drilling, which is manufactured by friction welding with a triangular arc steel pipe with a tapered transition and a drill pipe joint in the form of thread or triangle, square, hexagonal, etc.
Connection form: square connection, hexagonal connection and threaded connection, in use to cone thread connection
Product use
It is mainly used in drilling under the geological conditions of coal seam and near coal seam, coal mine water exploration and gas discharge drilling construction, and can also be used in geophysical prospecting and water conservancy construction engineering anchoring, drilling construction and other fields.
ProductsProcess
At present, the triangular drill pipe produced by our company mainly adopts friction welding process, which can be divided into two types from the material. One is the 42Crmoa joint material welded by triangular steel pipe, and both ends adopt friction welding process. The other is perforated round steel integral milling welding male 42Crmoa material, the male buckle is friction welding, and the female buckle is directly threaded on the perforated round steel.
ProductsPatent
Triangular drill pipe patent: Triangular drill pipe series products are patented products with independent intellectual property rights that our company has successively developed in recent years. A number of national patents were obtained:
Utility model patent certificate: a three-sided cone drill pipe for coal mine roadway drilling (patent number: 201120359764.1),
