2.4 SURFACE AIR COOLERS

2.4.1 Surface Air Coolers General

a. The coolers are straight tube type with headers on either end.

Supply new coolers that are identical to the existing coolers except where modified by these specifications. The new coolers must be dimensionally interchangeable with the existing coolers so they can bolt into the existing equipment.

b. Detailed air cooler drawings exist for Main Units 3-10. These coolers have mirrored lower heads, a left and right hand design. This is noted on drawing P-5923384. The Contractor must field verify all dimensions and document any additional measurements or features that are needed for fabrication. The original coolers have 204, 5/8" O.D.

tubes. There are 4 rows of 25 tubes and 4 rows of 26 tubes. There are 8 fins per inch. One in-service cooler is available to ship off site for reverse engineering or to inspect on site. The other hand cooler will be removed from service for the contractor to inspect on site only.

c. Detailed drawings for Main Units 1-2 are not available. These coolers are of the same family and manufacturer as units 3-10 only differing in size. The original coolers have 288, 5/8" O.D. tubes.

There are 12 rows of 24 tubes. There are 8 fins per inch. The contractor must certify that these coolers do not have mirrored heads.

The contractor will need to inspect and take all measurements of the Main Units 1-2 coolers in order to properly reverse engineer them. Two coolers will be removed from service for the contractor to onsite. One in-service cooler is available to ship off site for reverse engineering.

d. Detailed drawings for Main Units 11-18 and Fish Units 1-2 are not available. Main Units 11-18 original coolers have 92, 5/8" O.D. tubes.

There are 4 rows of 23 tubes. There are 14 fins per inch. Fish Units 1-2 original coolers have 72, 5/8" O.D. tubes. There are 4 rows of 18 tubes. There are 14 fins per inch. One existing cooler of each family will be made available to the Contractor for the purpose of reverse engineering off site or to inspect on site. The specifics regarding the availability of the cooler for reverse engineering is located in PARAGRAPH: Cooler Availability for Reverse Engineering.

2.4.2 Finned Tubing Main Units 1-10

a. Use copper L-fins that are tension wound to the copper tube. Make fins from copper that meets the requirements of ASTM B152/B152M.

b. Make the inner tubes from copper, per ASTM B111/B111M, UNS C70600.

The minimum allowable wall thickness is 0.049". Expand the tube ends into the tube sheets. Do not use belled ends on the tubes as the original tubes have.
