Heat exchanger tubes with internal grooves

WebGroovy fins have a grooved profile allowing an improvement in heat exchange of 8% to 15% for the same power consumption. Their pioneering and patented shape channels the air around the tube, maximizing the exchange surface. Products fitted with Groovy fins require less space and use 10% less electricity. WebA copy of Form 175 that is specialized for shell-and-tube heat exchangers is contained in Course Handout 3. API-660. Section 8 of API-660 presents inspection and testing requirements for shell-and-tube heat exchangers. For the precise wording set forth in the Standard for the inspection and testing requirements, refer to API-660.
