Fixed Flanged Exhaust Bellows
Flanges are welded rigid on both sides. 1/2" thick plate flanges are most common for exhaust and blower applications. Stainless and carbon steel flanges can be fabricated with any bolt pattern in any size.
Floating flanges or vanstone flanges eliminate bolt alignment problems. DME fabricates vanstone stub ends in stainless and other alloy materials. Carbon steel back up flanges are an economic solution....
A unique process allows us to form a vanstone end integral with the bellows. This eliminates a weld on one end. The fixed flange is generally an ANSI flange and the floating flange a Caterpillar, Detroit, Cummins, etc....
By design these joints have very low spring rates. On engine manifold applications, multi-ply expansion joints can absorb and isolate vibration and at the same time absorb certain amounts of thermal expansion. For critical applications such as marine and co-generation, multi-ply ...
The bellows length is generally limited to 12" in length. When a longer assembly is required, fabricated stainless steel tubes are used. For standby applications, carbon steel tubes are available....
This assembly clamps directly to the turbo charger. Multi-ply bellows have very low spring forces and will protect the turbo from the piping stresses. Assemblies can be furnished with any outlet fitting required....
