HEATEXCHANGER

A Total System Solution

Chesterton® Heat Exchanger SealingReliability Program

The design and function of heat exchangers presentone of the most difficult sealing applications in a plant.The wide range of operating conditions subject heatexchangers to severe thermal cycling and hydrostaticpressures. These tough conditions make it difficult to achieve a tight seal on the bolted flange joints.

Chesterton offers a Total System Solutionfor heat exchanger sealing that focuses on:

� Selecting the proper gasket

� Optimizing bolt loading

� Maintaining gasket sealing stress

We analyze the unique operating parameters of each heat exchanger application, to provide an engineered sealing system, improving plant efficiencies and reducingtotal operating costs.

� Meet current fugitive emissions and environmentalregulations

� Control leakage and product loss while minimizing safety and housekeeping concerns

� Reduce unscheduled downtime on production-critical heat exchangers

� Simplify maintenance requirements with a plantstandardization program

CHESTERTON HEAT EXCHANGER SEALING RELIABILIT Y

Our reliability program offers Outage and Turnaround Planning

� In-plant survey of heat exchangers and other critical flanges

� Complete engineering review of fluid compatibility, pressure, and temperaturecapabilities; gasket sealing stress; and bolted connections

� Comprehensive training programs for product selection, installation, and proper bolting techniques

� Logistics and planning support

Flange Live Loading Systems—Advanced sealing technology for a leak-free heat exchanger seal

We combine the best achievable sealing technologies to provide dramatic improvements in sealing reliability by optimizingbolt loading to maintain gasket sealing stress above the minimum required to maintain a leak-free bolted flange. Thesesystems are ideally suited for all heat exchanger applications, especially those subject to vibrations, pressure surges, andthe effects of thermal cycling. Contact your Chesterton representative for warranty details.

Steel Trap™Steel Trap provides improvedperformance at minimumgasket seating stress for thegreatest margin of reliability. It is the ideal replacementgasket in problem applicationssuch as heat exchangers andother critical flanges.

PROGRAM

Flange DiscsThese are designed specifically to eliminate springstacking on large heat exchanger stud bolts.

Manufactured from aerospace corrosion-resistantsteel used for jet engines and steam turbines—

applications where high temperature andvibration are present—our flange discs offerimproved performance over more common

flange disc materials. Chesterton Flange LiveLoading can provide dramatic improvements

in sealing performance and service life.
