Description
stainless steel exhaust bellows capsules are designed and
manufactured here at DME. Stainless steel, Inconel **5 and other
high nickel exhaust bellows are used in our expansion joints and
are available in a variety of designs and sizes. These types of
expansion joints can provide you with optimized vibration dampening
as well as thermal piping growth isolation at the engine exhaust
manifold. Expansion joints are required on such systems in order to
absorb the thermal expansion throughout the exhaust piping layout.
Here at DME, you can have your choice of single ply or multi-ply
exhaust bellow capsules. Let our sales engineers help you to select
just the right expansion joint for your system. We have fixed
flanged exhaust bellows expansion joints with many options for
custom flanges. Our ½" thick plate flanges are the most common and
economical connections being used in exhaust systems and blowers
today. DME keeps an extensive inventory of carbon steel and
stainless steel flanges ready to weld to the bellows. We also have
the Vanstone flange exhaust bellows assembly available for you
which have floating flanges that help eliminate bolt alignment
problems. The stub ends of the vanstone or floating flanges are
fabricated in stainless as well as other high temperature alloy
materials. Carbon steel as a material for back up flanges is also
available for customers as a more affordable alternative. We also
have multi-ply flanged exhaust bellows that gives customers the
benefit of using expansion joints that have a very low spring rate
and very high cycle life. Not only will these bellows absorb
certain amounts of thermal expansion, they can also help absorb and
isolate engine vibrations preventing damage to the piping system.
Multi-ply bellows expansion joints are vital for critical
operations such as in marine exhaust, prime power generators and
co-generation applications and also for critical back-up
generators.
Here at DME, we also have stainless exhaust bellows expansion
joints are also used for low pressure ducting systems that operate
at high temperatures. Our bellows size range is from **1/2” to **4”
inside diameters. Each bellows is designed and engineered with
state of the art EJMA computer programs. Custom designing a bellows
to meet the conditions of your system means you can expect the
ultimate performance and longevity. This is all available to you at
no additional cost or increased delivery times. Single-ply and
multi-ply bellows can be fabricated with carbon steel tube and pipe
ends ready for you to weld to your fittings or piping. DME also
manufactures tube end exhaust bellows that can be furnished in any
length required for any installation. This allows customers to
easily connect their own flanges or fittings to the tube ends
through welding. We can fabricate these bellows with ends in any
size, thickness or alloy.
We also manufacture exhaust bellows with flow liners if you require
them. A flow liner is an internal tube that will smooth out the
flow and prevent failure in high velocity applications. Here at
DME, we also manufacture several other expansion joint accessories
such as removable shrouds or covers, pyrometer ports, tie rods
etc…. Shrouds are required on some expansion joints in order to
protect the bellows from external damage or prevent personnel from
contacting the hot joint. The removable shroud can also help
deflect steam and other media in an event of a leak or pipeline
failure. DME offers you only the best products using only the best
materials that will provide you with exceptional performance. We
wouldn’t settle for anything less.
High pressure bellows expansion joints are also manufactured at DME
Inc. with the same high standards that we have been using for the
past *0 years. Our sales team and design engineers are ready to
assist you with your project. Each high pressure bellows is
carefully inspected and when used in an expansion joint is pressure
tested to insure a leak tight installation. Whether you require low
pressure exhaust bellows or high pressure steam bellows DME will
provide you with quality products every time
