Spiral Wound
These gaskets, made popular by the Flexitallic brand typically
feature an outer, or centering ring of carbon steel, and wedged
inside that ring, a winding of alternating strips of flexible
graphite and stainless steel. Inner rings, comprised of another
steel or stainless ring wedged inside the winding are required for
higher pressure classes. Inner and outer rings are available in
stainless steel, Monel, or carbon steel plus many other materials.
Windings can include 304 or 316 stainless steel or Monel for the
ultimate corrosion resistance. PTFE or Thermiculite filler can
substitute for graphite in some more severe processes.
Cut Rings
The most popular ring material is aramid fiber with NBR binder,
replacing asbestos in the USA years ago. Full face gaskets feature
bolt holes while ring gaskets do not. With our manufacturer’s
computer controlled laser and water jet cutters and your pattern we
can make any shape from any material specified.
Ring Type Joint
This high pressure gasket is a solid ring of steel that dovetails
inside the grooves between two matching flanges. Grooves and gaskets
are either oval or octagonal when viewed in cross-section. We will
often supply these along with high pressure valve and flange sets,
which together can handle pressures up to 10,000 psi.
Heat Exchanger
Gaskets
Heat Exchanger Gaskets can have intricate patterns called partitions
that must be perfectly crafted to match the pattern of internal
passageways of the exchanger. These are often specified as double
jacketed soft iron, steel, stainless steel or alloy sandwiched over
graphite cores.
Corrugated Metal
Gaskets
Corrugated Metal Gaskets are high performance gaskets for heat
exchanger or flanged applications. They feature a corrugated metal
form for strength, and a coating of flexible graphite for a surface
that conforms to your existing sealing faces. They mold in place
filling surface irregularities and creating a superior seal. It can
maintain this seal despite harsh effects of hydrocarbons or steam.
You can substitute a CMG for double jacketed heat exchanger gaskets,
cut rings or spiral wounds to solve challenging sealability
problems.
Kammprofile
This new technology utilizes micro-grooves in graphite faced steel
rings to provide positive seals longer and more reliably than
traditional metal jacketed or spiral wound gaskets. They provide
improved performance at lower seating stresses, and have excellent
anti-blowout properties. Need to reduce emissions? Kammprofiles
might be the solution.
Technical Support
Need help selecting the correct gasket style and material for
your application? Our partner manufacturer’s engineers can use your
data to select the correct gasket for your application. We will need
pressure, temperature, media type and the physical sizes and
finishes of the sealing surfaces. Give us a call; we’ll help you
out.
Packing
Valve stems, pump shafts, and propeller shafts all need packing to
survive the heat, vibration, abrasion and corrosion of heavy
industry. Picking the correct packing for your application is
critical, yet easy with our expert help. Typically braided or
extruded with a square cross-section, packing is rated to withstand
different shaft speeds, temperatures, pressures, corrosive chemicals
and abrasives. Carbon fiber, graphite, and Teflon are common
selections for highest performance.
Sheet Packing
You can fabricate your own gaskets with our sheet packing and a
gasket cutting set. We sell several styles of gasket cutters. Aramid/NBR,
graphite and carbon fiber are popular, some with stainless steel
"tang" inserts, along with rubber, Teflon and cork.
O-Rings
O-rings are everywhere! If it has a size, it can be replaced.
Traeger can supply boxed assortments of O-rings, or o-ring kits with
rubber cord by the foot and glue to assemble the exact sizes
required.
Mechanical Seals
Complicated sets of spinning rings and springs, mechanical seals are
the choice for high powered pumps and machinery. Our partner
manufacturers can replace many modern mechanical seals.
Oil Seals
If you’ve got oil, you’ve got oil seals. Why not replace them now,
along with some new bearings and avoid costly down time later.
Better get a couple spares too. Send us your spec, we’ll get them on
your shelf.
