Jacketed gaskets
Features
Buralloy metal-jacketed gaskets are
produced in a wide variety of different
materials (in various combinations), in
many cross-sections and in many styles.
They are suitable for flanges in heat
exchangers, pipe flanges, boilers and
process equipment.
Design
Metal-jacketed gaskets, as the name
suggests, consist of:
• Metallic outer shell with either a metallic
or non-metallic asbestos-free filler
• The filler material gives the gasket
resilience
• The metal jacket protects the filler and
resists pressures, temperatures and
corrosion
Materials of construction

Technical data
Pressure and temperature parameters in
accordance with customer specifications.
Corrosion resistance is dependent upon
the choice of materials. Please ask for
advice if you are uncertain of the correct
selection.

Profile
Variant number
Application
2500/BHX200
Flat metal
年代uitable for valve bonnets, heat exchangers, tongue and groove joints.
Requires relatively high bolt loads.
2521/BHX210
Flat metal – graphite-covered
年代uitable for valve bonnets, heat exchangers.
Graphite facing provides excellent adaptability.
2522/BHX220
French style – single-jacketed
Used in air tools, engines and where space is limited.
Narrow width of gasket face <5 mm.
2523/BHX230
French style – double-jacketed
简单的像BHX220垫片。
For wider gasket face width s >5 mm.
2524/BHX240
年代ingle-jacketed – open style
简单的像BHX220垫片。
For wider gasket face width s >5 mm.
2525/BHX250
年代ingle-jacketed – totally enclosed
Used when filler material must be totally protected.
2526/BHX260
Double- jacketed – totally enclosed
Most commonly used form of jacketed gasket. Can be made to almost any size and for most applications.
Can be applied in standard flanges when the required compression is higher than is allowable for cut fiber gaskets.
2527/BHX270 2527/BHX270
Double-jacketed – double shell, totally enclosed
年代imilar to BHX260 but for higher compressive forces.
Extremely robust.
