Pipe Bending
Long U-tube over 20m is available
U-bent tube is our strength product. We provide integrated production from manufacturing of raw pipe (STB, STBL, STBA: S - C, E - C) to bending. We are constantly setting up an emergency instant delivery system at all times.
Especially, our company have the heat treatment furnace to remove the residual stress on the bent part.
Moreover, we ensure to manufacture U-bent pipes by our skilled craftsmen who can minimize the dimensional variation.
With first-ranked Japanese mother tube along with the experienced process of production as well as strict inspection, we are proud to be the number one manufacturer of tubes for heat exchanger in Japan.
Potential range of manufacturing
In some cases, it may be possible to work outside the potential range of manufacturing. Please feel free to contact us.
Material
We manufacture with carbon steel tube, alloy tube and stainless tubes. Please also contact us with other materials.
Dimensions
Pipe outer diameter 38.1 mm or less. Straight length up to 21.3 m.
Others
Bending part stress relief annealing (carbon steel, alloy steel only), water pressure test are both available on request. For the outer diameter change rate, wall thickness reduction rate, pitch, bending radius, straight section length and other quality, we process according to JIS, ASTM, ASME, high pressure gas regulations.
