Heat Exchangers
DTS
DTS(Dimpled Tube Support)
By inserting DTS (STS*) dimpled and corrugated metal strips in between tubes, vibrations are suppressed and the tube bundle is strengthened.
※STS(Saddled Tube Support Technology) …effective with soft metal finned tubes.
- Can be easily installed in existing bundles
- Capable of eliminating tube vibration noise
- Increases the natural frequency of the tubes to lessen vibration
- Able to be used in U-bend sections as well
Compatible with a wide range of laws and regulations,including the Industrial Safety and Health Act and the High Pressure Gas Safety Act
Japanese Regulation
- Industrial Safety and Health Act (Boilers, Class-1 Pressure Vessels, Class-2 Pressure Vessels, Small-size Boilers,Small-size Pressure Vessels)
- High Pressure Gas Safety Act(Specified Equipment Inspection Regulations, Refrigeration Safety Regulations)
- Electricity Business Act (Process I certified welding factories)
- Gas Business Act
Able to manufacture a diverse array of chemical engineering equipment in specialized materials
