GASKETS
1. Spiral Wound Gaskets
-
The optimum filler denisty is constant and Tested across the windings for consistent compression and superior sealability
-
Durable; easy installation and removal
-
Seals pressures to flange ratings, in accordance with ASME B16.5
-
Suited to temperatures from cryogenic to 2000°F (1093°C), depending on metal and filler.
-
Guide ring simplifies centering of sealing element on the flange face
-
Custom-tailored solutions accommodate a variety of conditions by combining various metals and filler materials
STYLE CR ( Without inner Ring ) :
-
General purpose gasket suitable for raised face flanges up to Class 2500
-
Centering ring accurately locates the gasket on the flange face, provides additional radial strength, and acts as a compression limiter
-
Spiral winding (sealing element) consists of preformed metal and soft filler material
STYLE CRI ( inner Ring ) :
-
Suitable for raised face flanges up to class 2500# flanges
-
Inners rings are recommended by ASME B16.20 unless otherwise specified
-
Inner ring acts as compression limiter and protects sealing elements from process media attack
2. RING JOINT GASKETS
-
Centering ring accurately locates the gasket on the flange face, provides additional radial strength, and acts as a compression limiter
-
Spiral winding (sealing element) consists of preformed metal and soft filler material
-
Inner ring (RWI-RJ) acts as compression limiter and protects sealing elements from process media attack
-
Ideal replacement for solid metal oval or octagonal API ring joint gaskets
-
Saves cost of flange replacement when gasket groove is badly worn
-
Fast and easy installation-requires only a 3/16" flange separation (ring joint gasket may require as much as 3/4")
-
Wide variety of metal and filler materials have a full range of temperature and pressure capabilities
-
The optimum filler denisty is constant and Tested across the windings for consistent compression and superior sealability
-
Not stocked, but can be special-ordered
3. Kammprofile Gasket
Serrated solid metal core
-
Serrations concentrate bolt load on small area for tight seal at lower stress
-
Solid metal core resists cold flow, overcompression and blowout
-
Rigid core provides exceptional stability, even in large sizes, and facititates handling and installation
Soft, deformable sealing material
-
Under compression, fills seating surface imperfections to form a tight, metal-to-metal connection
-
Seals under low stress-ideal for weaker flanges
-
Withstands extreme fluctuations in temperatures and pressures
-
Optional convex root core compensates for flange weakness and counteracts flange rotation
-
Integral centering ring ensures optimum gasket positioning
-
Floating centering ring attached outside sealing area compensates for expansion and contraction during thermal cycling
APPLICATIONS :
-
Accommodates standard ASME flanges as well as weaker and non-circular flanges
-
Economical replacement for jacketed heat exchanger gaskets
-
Seals less-than-perfect flanges
-
Handles pressures from vacuum to Class 2500
4. Rubber Expansion Joints
Expansion joints are specially engineered products inserted in a rigid piping system to achieve one or more of the following:
-
Absorb movement
-
Improved thermal stability
-
Relieve system strain due to thermal change, load stress, pumping surges, wear or settling
-
Reduce mechanical noise
-
Compensate for misalignment
-
Eliminate electrolysis between dissimilar metals
Non-metallic expansion joints and flexible couplings are ideally suited for hundreds of applications in a wide range of industries, including:
-
Power Generation
-
Pulp and Paper
-
Chemical Processing
-
Water/Waste Water
-
Marine
-
Mining
Ordering Information
When ordering specify:
-
Inner ring and winding dimensions (and tolerance, if other than standard)
-
Thickness of gasket
-
Winding and filler materials
-
Inner ring material
-
Pressure rating
