How to solve the deformation problem of spiral seam submerged arc welded steel pipe
The spiral seam submerged arc welded steel pipe rotates and starts to enter the soft formation. Under the action of the tri-cone, the drill bit first produces elastic shear deformation of the formation, and then it is removed under the pressure of the tri-cone. In the simulated environment, the s...Read more -
