Detail of the Tuper Quick Connection
Tuper Tubular Stakes use the innovative quick connection concept for seams eliminating the need to weld and speeding up the setting process.
They are manufactured in carbon steel with a flow limit above 310 MPa, and meet the requirements of standard ASTM A252:2019 – Grade 3. Presents characteristics that render the product more economic and efficient, reducing the time of the setting process and increasing productivity in the work. With that, the Tuper pile seam uses a ready, easy to handle part that is manufactured with precision for internal coupling. The positioning and alignment of the seam is made in the construction site with tubular piles, and the coupling occurs by pressing with the energy of the pile-driver hammer blow
The loads are transferred by the direct contact of the tube faces and by the high friction, cold welding style, generated in the seam pressing. The compression is fully transmitted. Bending and tensile efforts have had their ruptures determined by testing.
Tuper offers mixed steel and concrete piles, providing a solution with intermediate cost when compared to only concrete piles or steel piles, therefore maintaining the advantages of metal piles with the possibility of time optimization if used with the quick connection feature.
