Spiral Wound
These gaskets typically feature an outer, or centering ring of carbon steel, and
an inner winding of alternating strips of flexible graphite and
stainless steel. Inner rings 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 stainless steel or Monel for the ultimate corrosion resistance. PTFE filler can
substitute for graphite in some caustic processes.
Cut Ring
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.
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. 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. Order
assortments or o-ring making kits, and rubber cord by the foot.
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.
