Maruichi Stainless Tube Co., Ltd. has established the secondary forming process of low-finning from outside of tubes. This process is applied not only on the conventional stainless tube but also on the material with hard to work.


  1. High density and integrally cold formed fin on the out side of a tube can dramatically improve heat transfer efficiency.
  2. The modified roll forming technique is applicable to many kinds of stainless steel and high alloys.
  3. Because these types of tubes are made of unit, the durability and anti-vibration properties are good.
