Dredging Hose features "customized" heavy-duty, wear-resistant constructions employing the finest grades of natural and synthetic rubber and fabric. Produced in hard and soft-wall constructions, S-R's Dredging Hose is quality-based with over 30 years of experience in handmade hose design and manufacturing.
S-R engineers and manufactures the complete hose assembly from formulation of all rubber compounds to vulcanizing the finished hose. This is your assurance that all raw materials used in production are compatible with each other and most suitable for the intended use of the hose.
If your requirements include flexibility, stability, vibration damping or resistance to abusive handling.
Suction:
S-R's tough hard suction hose features a custom-blended rubber lining that resists the most severe cutting and abrasive action. Spring steel helix wire with multiple synthetic textile reinforcement provides for full vacuum, kink resistance and vibration dampening.
Discharge:
Hard-wall (SDH) and soft-wall (SDS) discharge hose are designed to meet your needs. Hard-wall where bend radius is controlled, soft-wall where kinking is unavoidable.
Sleeve:
Only the best ... S-R's unique construction includes use of high tensile synthetic tire cord. Guarantees no-swell O.D. under pressure. No "ply ratings" ... the number of plies stated is actual count.
Gimbals:
Specifically designed to exacting specification for individual hopper dredges.
Custom Tube Linings
Supplied to customer needs and are made of the highest quality custom blends of natural and synthetic rubber.
Custom Tube Thickness
To meet special needs of materials being handled, hose diameter, and service conditions. S-R's own recipes are compounded to resist abrasion and cutting.
Reinforcement
Multi-ply synthetic fabrics assure maximum tensile strength and ability to absorb shock and vibration.
Custom Cover
Supplied with wear-resistant SBR for cut and abrasion resistance, or a tough neoprene for salt-water service with added resistance to ozone and sunlight.
Custom Lengths
Up to 50 ft., diameters to match pipe I.D.'s or O.D.'s up to 42".
