Specification of U-bend section
- If the customer did not particular order about the specification of U-bend section, we apply High Pressure Gas Safety Act.
- We are able to handle other specification of U-bend section such as JIS(for steel tube), ASTM B395(M), ASME SB395(M), TEMA etc.

Low-fin tube
Low-fin tube
- Low-fin is continuously molded on a tube by rolling process, and low-fin tube has high heat transfer efficiency, durability, high resistance against vibration as fin and tube are united.
- Compare to normal tube, Low-fin tube has much bigger high heat transfer area, it would allow to decrease the size, weight of heat exchanger then reduce the cost.
- As fin and tube are united, tehre is no separation by u-bend fabrication, especially annealed tube is easy to bend.
- No fininig area shall be according to the customer's request(f.g. both tube end, middle section of tube).
