• Processing Contract

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.
