Cal-Fin Tubes

California Finned Tube Company (Cal-Fin) specializes in manufacturing high performance tubes for the heat exchanger industry. We stock prime surface tubing in several alloys, wall thicknesses, and diameters. We can produce integral fin tubes from the following materials:

• Copper Alloy 122
• Carbon Steel SA-178, SA-214
• Stainless Steel Type 304L, 316
• Cupro-Nickel 95/5, 90/10, and 70/30
• Brass 443, 445, 687
• Titanium SB-338 Grade 2

We specialize in smaller orders for your heat exchangers, with short delivery turnaround. A typical two hundred tube order is produced in a few days compared to four to eight weeks from our competitors. We can match most OEM replacement tubes or even increase the surface area with our rifle chill tube design to improve efficiency. Our finned tubes can be manufactured with 19, 26, and 40 fins per inch. We can internally groove the ID and further enhance the 00 of the tube. Our company can fin tube diameters from 1/2" through 1" in the alloys listed. We also produce star insert tubes for the air conditioning industry.

Uninterrupted service is critically vital to these operations. Thousands of dollars can be lost through unscheduled shutdowns or failures. Replacement tubes are manufactured to ASME or MIL-T specifications when required. Our service division can also perform the replacement of your tubes if needed.

Contact us or call us at 800-356-1932 for more immediate attention, with the model of your equipment so that we can better assist you in the repairs of your condenser, evaporator, or heat exchanger. It is also possible to increase your heat exchanger tubes' efficiency by increasing the fins per inch, or I.D. rifling grooves to gain more surface area and pressure drop by keeping fluids in the tube longer.
