  • How to solve the deformation problem of spiral seam submerged arc welded steel pipe

    How to solve the deformation problem of spiral seam submerged arc welded steel pipe

    The spiral seam submerged arc welded steel pipe is drilled in rotation and begins to enter the soft formation. Under the action of the tri-cone, the drill first produces elastic shear deformation of the stratum and then is removed under the pressure of the tri-cone. In the simulated environment, ...

  • What is the difference between cold drawn steel pipe and hot rolled steel pipe

    What is the difference between cold drawn steel pipe and hot rolled steel pipe

    (1) The difference between hot working and cold working: hot rolling is hot working, and cold drawing is cold working. The main difference: hot rolling is rolling above the recrystallization temperature, cold rolling is rolling below the recrystallization temperature; cold rolling is sometimes he...
