Product family
Expanders
Expansion joints for pipe movement and pressure expanders for process systems.
Range overview
Expanders for process, utility and critical service.
Piping expansion joints absorb thermal, mechanical and seismic movement. Pressure expanders provide controlled volume and flow regulation in process and utility systems. Both lines are built to project-specific movement, pressure and material requirements.
- Primary standards
- EJMA · ASME B31.3 · ASME Section VIII · ISO 9001 manufacturing
- Supply scope
- Standard and made-to-order configurations; project documentation on request.

How to specify
Three inputs are enough to start.
A complete RFQ shortens the review cycle. If a drawing or existing part number is available, include it with the enquiry.
01
Duty and envelope
Size, pressure class, temperature, media and available space. For movement or flow duty, include the calculated range.
02
Material and connection
Pipe or vessel material, flange facing, weld or thread detail, and any sour-service or NACE requirement.
03
Documentation and test
Material certificates, NDE, pressure test, dimensional report and any project specification or data sheet.
