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
