Tranter Expands Applications Of

Superchanger Heat Exchangers

Following years of extended test- ing, including vibration per MIL-

STD-167, shock per MIL-S-901C, thermal, pressure drop and gasket sealability, Tranter SuperchangerR plate and frame heat exchangers with designated marine features are now on 16 classes of U.S. Navy ships, particularly for electronic cooling.

This program is the result of

Tranter's addressing the Navy's need for a cooler that would be resis- tant to corrosion and erosion by seawater. Years of tests in the fleet verified that plate heat exchangers with titanium plates are totally re- sistant to both of these conditions, even at elevated velocities. In many cases, the only required mainte- nance has been periodic backflushing of the units. In addi- tion, the high turbulence in the plate heat exchanger helps mini- mize biofouling and maintain high heat transfer conditions.

These findings have justified the replacement of numerous shell and tube electronic coolers with copper- nickel tubes that have failed on ships with Superchanger units.

Signature. 20 other applications has already been logged by Navy T-AO fleet oilers, commercial containerships and tankers, barges and dredges.

The newest applications for

Superchanger exchangers have in- cluded engine cooling on the MAf

Mississippi towboat owned by the

U.S. Corps of Engineers, and the 224-foot wooden MCM-14 Counter- measure Ship "Chief' launched in

June. Aside from being erosion and corrosion resistant, these titanium- plated heat exchangers reportedly offer other advantages, including: favorable price, space and weight specifications; ease of maintenance and repair; and resistance to fouling due to high turbulence. The units, which have recorded excellent test results in the fleet, comply fully with

ABS and U.S. Coast Guard require- ments. Tranter's model selection offers capabilities up to 16,000 gpm.

Maximum design pressure ratings for the Superchanger frame configu- rations vary from 150- to 350-psig.

Design operating temperatures fluc- tuate from -22 to 350°F based on the gasket material. For additional free information,

NNS Joins Yards In Bid For

Building Eight LNG Carriers

Newport News Shipbuilding (NNS) has joined with three other shipyards—IHI, Fincantieri and

Sumitomo Heavy Industries~in sub- mitting a joint budgetary proposal to build eight 138,000-cubic-meter

LNG carriers for the Italian gas util- ity Snam. NNS also signed a formal license agreement with IHI that al- lows NNS to use IHI design technol- ogy to build LNG tankers. NNS now has obtained licenses for all four major LNG containment system de- signs. For free information on NNS,

Metro Machine Wins U.S.

Navy's AEGIS Award

Metro Machine Corp. was hon- ored by the U.S. Navy for demon- strating superior performance in quality, reliability, delivery and cost on the U.S.S. Ticonderoga (CG-47) overhaul, the first overhaul of an

AEGIS cruiser. The Navy has rec- ognized the Norfolk-based ship re- pair and modernization firm by awarding it its 1993 AEGIS Excel- lence Award.
