ST52 Concrete Pumping Pipe Tube


ST52 concrete pumping pipe is the most popular tube pipe for distributing concrete, and it is welding SK end mostly. ST52 concrete pumping pipe have good performance which that flatten without cracks, cold bending without deformation, and can withstand high pressure. Usual, for concrete pouring engineering, Putzmeister ZX pipe and ST52 pipe use together with different pressure.

Tips for enlarging ST52 concrete pumping pipe service life

  • Order the operation rules, and reduce the distribute concrete length when working.
  • Rotation 180 angle of st52 concrete pumping pipe tube timely.
  • Clean the pipe tube by sponge cleaning balls after the pouring immediatly.
