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.
ST52 is Germany standard, and it is called 16Mn in China.

ST52 concrete pipe have high mechanical properties, Its performance determines the distance of the transportation.
