Great here's a complete technical and practical overview of a Fly Ash Rubber Hose with Fixed Flange, typically used in pneumatic conveying systems like silo discharge, ash handling plants, and bulk material transfer systems.
This type of hose is engineered to handle abrasive dry materials like fly ash, cement, sand, or lime under low to medium pressure, with reinforced rubber lining and flanged ends for secure connections.
| Parameter | Typical Values / Range |
|---|---|
| Inner Diameter (ID) | 50 mm to 300 mm (2 to 12) |
| Length | 1 m 10 m (custom lengths available) |
| Working Pressure | 5 10 bar (72 150 psi) |
| Burst Pressure | 3x working pressure (15 30 bar) |
| Temperature Range | -20C to +80C (can be customized with special rubber compounds) |
| Lining Material | NR/SBR/NRR (anti-abrasive natural rubber blend) |
| Reinforcement | Multiple layers of synthetic fabric + steel wire helix |
| Outer Cover | Weather-resistant SBR/NR blend, optionally wrapped or smooth |
| Flange Type | Fixed MS Flanges (IS/ANSI/DIN standard drilled), vulcanized or clamped |
| Flange Type | Standard | Connection |
|---|---|---|
| Mild Steel (MS) | IS 1538 / ANSI B16.5 | Bolted connection, PN10PN16 |
| Galvanized MS | For corrosion resistance | Optional |
| Rotatable/Swivel Flange | Available on request | For easy alignment |
Flanges are usually vulcanized with steel rings for permanent fixing or externally clamped with heavy-duty bands.
Tube (Inner Layer): Abrasion-resistant rubber (black)
Reinforcement: Multi-ply synthetic cord + steel wire helix
Cover: Anti-weather, anti-aging rubber (black or optional color)
Ends: Fixed steel flanges (welded or integrated)
| Hose Size | Packing Style |
|---|---|
