3.application area of water well drill pipe
1. Water conservancy engineering: used for drilling various types of water wells, including agricultural irrigation wells, urban water supply wells, industrial water wells, etc., providing key support for obtaining groundwater resources.
2. Geological exploration: In geological exploration work, assist in drilling geological samples, understand underground geological structures, rock distribution, etc., and provide a basis for mineral resource exploration, geological hazard assessment, etc.
3. Mining: Assist in the drilling and excavation work of mines, such as coal mine water exploration, gas exploration, tunnel exploration and other operations, to ensure safe production of mines and improve resource development efficiency.
4. Construction engineering: In the construction of building foundations, it is used for pile foundation drilling, underground continuous wall construction, etc., to provide stable foundation support for buildings.
Maintenance of water well drill pipe
Clean the mud and rock debris on the surface of the drill pipe in a timely manner after homework to avoid corrosion;
Check whether the joint threads are worn or deformed, regularly apply thread grease to ensure the sealing of the connection;
When storing, avoid outdoor exposure to sunlight and rain. Apply anti rust oil and place it flat or hang it to prevent bending and deformation;
Regularly conduct non-destructive testing (such as ultrasonic testing), check for internal cracks in the rod body, replace damaged drill rods in a timely manner, and avoid safety accidents.
