Manufacturing Capabilities
Bellows Materials
Based on operating temperature + media + pressure requirements
+ desired life cycle
– 300 Series Stainless Steel (any type of general service:
H=high temperature, L=low carbon content)
• 304, 304L, 304H, 316, 316L, 316H and 321
– High Nickel Materials
• Monel 400 (sea water, high corrosive) and Inconel 600
(seawater/marine)
• Inconel 625 LCF (low cycle fatigue): oil refineries & chemical
plants in high temperature service due to high strength at high
temperatures

– Liner and flange used to be 2 pieces
– We combined the liner and flange into
one piece
– As result, there is less welding for us
and a smoother flow in the duct work
for them
