Flexible Joint
Metal Expansion Joint
High-precision stainless steel and high-alloy bellows expansion joints engineered for thermal expansion compensation in high-pressure steam, oil, and gas piping.
Description
Metal Expansion Joint
Precision-engineered stainless steel and high-alloy bellows expansion joints manufactured to absorb severe thermal expansion, pipe stress, and vibration in pressurized liquid and steam piping. PT Misuba Guna Indonesia supplies custom metal expansion joints featuring hydroformed or roll-formed multi-ply bellows (SS304, SS316L, SS321, or Inconel 625) engineered to withstand cyclic thermal fatigue and high working pressures.
Available in axial, tied-lateral, universal, hinged, and gimbal configurations to resolve complex thermal growth in restricted pipe runs.
Custom Engineering Consultation & Ordering Guide
To receive a precise engineering proposal for metal expansion joints, please submit your pipe nominal bore (DN/NB), design pressure (PN rating or ANSI class), design temperature, fluid media, and target cycle life. If your piping layout includes anchors and guides, share the isometric drawing for optimal bellows selection.
Features
- Multi-ply bellows design provides high pressure capacity combined with low axial spring rate and maximum flex fatigue life
- SS321 and SS316L standard bellows offer exceptional resistance to high-temperature scaling and stress corrosion cracking
- Internal flow sleeves minimize pressure drop and prevent flow-induced vibration in high-velocity steam lines
- External protective covers prevent external mechanical damage and debris accumulation in bellows convolutions
- Available with fixed/floating flanges, butt-weld ends, or threaded pipe stubs matching international standards (DIN, ANSI, JIS)
Applications
- High-pressure steam distribution headers and condensate return lines
- Thermal oil heating systems in palm oil refineries (PKS) and oleochemical plants
- Petrochemical refinery process piping and heat exchanger nozzle connections
- District heating pipelines and power plant steam turbine cross-over piping
- Marine engine exhaust manifolds and ballast water piping
