Overview
ISO 28017:2026 provides comprehensive specifications for wire- or textile-reinforced rubber hoses and hose assemblies used in dredging applications. This international standard applies to hoses with nominal sizes from 100 mm up to 1,300 mm, ensuring reliable performance for both delivery and suction of mixtures comprising seawater or freshwater with materials such as silt, sand, coral, and small stones. The document defines requirements for material quality, construction, performance, testing, and marking to ensure safety and durability in diverse dredging environments.
Key Topics
-
Types and Classification
- Two main types: Type 1 (floating, delivery only) with integrated flotation for buoyancy, and Type 2 (submarine, for delivery and suction).
- Seven pressure classes (from 0.5 to 4.0 MPa) and, for Type 2, three construction grades (A, B, C).
-
Material and Construction Requirements
- Hoses must feature abrasion-resistant rubber linings and covers, with steel or textile reinforcement as specified.
- Type 1 hoses include closed-cell flotation material; Type 2 hoses are designed for both delivery and suction.
-
Dimensional Tolerances
- Strict tolerances for inside and outside diameters and lengths are specified to ensure uniformity and compatibility.
-
Performance Characteristics
- Requirements include hydrostatic strength, bending ability, minimum burst pressure, vacuum resistance, and buoyancy for floating hoses.
- Additional criteria cover abrasion and ozone resistance, temperature brittleness, adhesion between components, and visual examination.
-
Testing and Certification
- Specifies the frequency and scope of both type- and routine-tests (e.g., hydrostatic, bending, tensile strength).
- Detailed marking requirements for traceability and product identification.
Applications
ISO 28017:2026 is essential for professionals involved in:
- Dredging Operations: Ensures hoses used for moving sediment, gravel, and mixed materials in ports, waterways, harbors, and reclamation projects perform reliably.
- Marine and Coastal Engineering: Hoses specified in this standard are ideal where robust performance in seawater and freshwater is critical.
- Mining and Aggregate Industries: For transporting abrasive slurry mixes in challenging environmental conditions.
- OEMs and Hose Manufacturers: Provides a benchmark for designing and producing dredging hoses that meet consistent international requirements.
Using ISO 28017:2026 helps organizations minimize downtime, reduce the risk of hose failure, and safeguard personnel and equipment during dredging projects.
