It is possible to bend with a small radius without creating cracks, even with a thick diameter! Compared to welding processes using elbows, it contributes to reducing labor and costs for welding, deburring, and other processes.
Bending a pipe with a diameter and bend radius of 1:1 is referred to as 1D bending (minimal radius bending). As the radius decreases, bending processes become difficult due to issues such as cracking in the pipe. At Tsukuba Iron Works, we are capable of 1D bending processing from small diameters of φ34 to φ114.3, thanks to our years of know-how and experience. Additionally, we possess various molds for 2D and 3D bending, allowing us to accommodate any conditions. 【Features】 ■ Cost reduction ■ Reduction of welding points ■ Elimination of elbows ■ Reduction of pipe cutting points ■ Reduction of burr removal *For more details, please download the PDF or feel free to contact us.

Company information
Founded in 1950. Manufacturing hydraulic piping for large construction machinery in Ota City, Tokyo. We handle everything in-house from material procurement, cutting, pipe bending, secondary processing, welding, to painting. To meet a wide range of needs, we possess numerous bending molds, including 1D bends (minimum R) with a maximum diameter of φ114.3. In June 2018, we established a new factory in Joso City, Ibaraki Prefecture for zinc phosphate coating (Parkerizing) and painting. By being able to perform surface treatment in-house, we have successfully reduced delivery times and costs significantly. With a 7m³ tank, we can also process relatively large products.
