This is interlock territory. On the dilute-phase and gravity lines the medium is abrasive and near-atmospheric, so tightness matters far less than wall thickness and the ability to survive particles moving fast against the bore.
Applications and the products that suit them
| Application | Product |
|---|---|
| Dilute phase pneumatic conveying | Interlock hose with heavy strip |
| Dense phase conveying, where the line holds pressure | Braided corrugated hose — interlock is not pressure-tight and we will not supply it for this |
| Dust extraction ducting | Interlock hose in 304 |
| Silo and hopper discharge connections | Interlock hose with sacrificial inner coil |
| Rotary valve connections | Interlock hose or Lateral / universal joint |
| Baghouse and cyclone connections | Lateral / universal joint in 304 |
| Weigh hopper isolation | Lateral / universal joint tied — keeps load cells honest |
| Truck and rail loading spouts | Interlock hose in 304 |
Specification notes for this sector
- Interlock over corrugated wherever solids are conveyed — corrugation valleys erode
- Sacrificial inner coil where the abrasion is severe
- Weigh hopper connections must have near-zero spring rate or the weights are wrong
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.
