Paper mills run hot, wet and chemically aggressive, often all at once. The failures here are corrosion-led far more than mechanical, and the chlorides in bleach plant service are the thing to watch rather than the pressure.
Applications and the products that suit them
| Application | Product |
|---|---|
| Dryer can steam and condensate connections | Braided corrugated hose in 316L — the classic dog-leg assembly |
| Digester and blow line connections | Axial expansion joint with liner |
| Stock and white water lines | Braided corrugated hose in 316L |
| Bleach plant chemical transfer | PTFE-lined assembly where chlorides are high |
| Vacuum pump connections | Braided corrugated hose rated for vacuum |
| Lubrication lines to dryer bearings | Braided corrugated hose small bore, double braid |
| Recovery boiler duct expansion | Axial expansion joint in 321 with liner |
Specification notes for this sector
- 316L as the working grade; review chlorides in bleach plant service
- Dryer can assemblies flex continuously — design to the dynamic bend radius
- Steam service: derate for temperature, not for pressure alone
What to send with an enquiry
Bore, medium, pressure, temperature, movement and both end connections. The reasoning for each is on how to specify an assembly.
