A Collection of Heat Exchanger Gaskets

Heat Exchanger Gaskets

Heat exchanger gaskets come in several forms based on the type of heat exchanger or application.  For simplicity’s sake, we use the terms metal jacketed, camprofile and plate to define the different types of heat exchanger gaskets, though there are numerous configurations for each type.

We precision engineer a wide range of gaskets for shell, tube, plate and frame heat exchangers gaskets, which are commonly used in operations involving steam generation and heating/cooling processes.

Metal Jacketed

Metal Jacketed

Heat exchanger gaskets and small spinner gaskets can be fabricated in simple rings or more complicated crossbar designs and configurations.

 Camprofile Gaskets

Camprofile Gaskets

Composed of a grooved metal core and a graphite or composite sealing layer, camprofile gaskets are supplied in standard and nonstandard dimensions.

Plate and Frame Gaskets

Plate and Frame Gaskets

Rubber gaskets are essential components in plate heat exchangers. We precision manufacture gaskets to size and thickness to suit the PHE.

The Manufacture of Metal Jacketed Heat Exchanger Gaskets

Metal jacketed heat exchanger gaskets can be supplied in circular or non-circular form, in standard or non-standard sizes. The gaskets are manufactured in different styles to API, ANSI, DIN and BS standards for all types of applications. The selection of gasket style and metal depends upon the operating conditions and the mechanical features of the flanged assembly.

We can also design custom metal jacketed gaskets based on customer specifications and our specialist knowledge ensures gaskets are fabricated to fit accurately and have an effective seal. Contact us to discuss custom requirements.

Key Features

  • Custom built to provide accurate and easy assembly of gasket partition bars into the tubesheet grooves.
  • Weld-in bar exchanger gaskets offer benefits over one-piece gaskets with integral bars, including a long sealing life - bars seal independently of the outer ring.
  • Available to customers specific requirements and designed to API 601 for ANSI B 16.5 and API 605 Flanges. Available from 1/2" n.b. to over 150" diameter.

Heat Exchanger Gasket Materials

Tube and shell exchanger gaskets are fabricated using a soft resilient material that is shrouded with metal to provide additional mechanical strength. Metal clad gaskets are frequently used with narrow flanges. This combination produces a strong resilient gasket which can be fabricated into complex shapes.

The overlapped seams produce a locally high seating stress which contributes to the effectiveness of the seal in critical areas. The crucial sealing area is the peripheral ring which prevents media leakage to atmosphere. Slight leakage across the pass-bars is tolerable since the exchanger manufacture builds-in a designed efficiency-loss catering for leakage at this point.

We recommend that double jacketed gaskets to be designed and dimensioned to allow at least 10mm Radius at all intersections.
