Built to handle the toughest conditions
so your operation keeps running
Reinforced rubber suction and discharge hose for mining, petrochemical, desalination and bulk-material handling — manufactured in Thailand to ISO 9001:2015 standard, in 3:1 standard or 4:1 premium reinforcement, with fixed pricing for up to 24 months.
Every bar of pressure is looking for the weakest point in the wall
Water, slurry, cement and air don't just move through a hose — under working pressure, they push outward against every millimetre of the wall, all the time. A hose that's under-reinforced for the job doesn't usually fail gradually; it fails suddenly, at the worst possible moment in a suction or discharge cycle.
The steel-and-canvas reinforcement ply is what turns a rubber tube into a pressure vessel. It's tested to hold at least 1.5× working pressure under hydrostatic load and built to a 3:1 safety factor as standard against burst — with a 4:1 premium option available where a project calls for extra margin — so the number on the spec sheet has margin built in before it ever gets close to the number that matters on site.
Two tiers - the same testing rigor
3:1 Safety Factor
- The baseline build across the full hose range — no special order, standard lead time
- Matches the accepted design factor for large-bore suction, discharge and dredge-type hose
- Right fit for most dewatering, transfer and general process duty
- Hydrostatic and vacuum tested on every batch
4:1 Safety Factor
- Additional steel-cord and canvas reinforcement, burst-tested to a 4:1 design ratio
- Available across all four duty classes — water, cement/sand, oil and air
- Matches the more conservative design standard some mining and EPC specifications require
- Tested burst-pressure data available on request, not just a nominal rating
Both tiers share the same bore range, flange options and quality framework. Clients specify which tier a project calls for when requesting a quote.
Four duty classes - one construction standard
Every hose is ordered against the same quality framework — steel-and-canvas reinforcement in a 3:1 standard or 4:1 premium build and in-house pressure testing on every batch.
Water Suction & Discharge Hose
- General-purpose duty: dewatering, transfer and non-corrosive liquid handling
- Natural or synthetic rubber tube, high elasticity to absorb pump-side surge
- Steel-and-canvas reinforcement — 3:1 standard or 4:1 premium
- Flangeless, slip-on, or built-in flange to PN10, PN16, ANSI, TIS, or JIS
- 2″ – 28″ bore, up to 20m per section
Cement & Sand Suction / Discharge Hose
- Abrasion-resistant tube compound for cement, sand and other bulk solids
- Handles dry or slurried abrasive material without premature wear-through
- Same steel-and-canvas reinforcement — 3:1 standard or 4:1 premium
- Textured, smooth, or wavy surface finish to suit handling equipment
- 2″ – 28″ bore, up to 20m per section
Oil Suction & Discharge Hose
- Synthetic rubber tube compatible with oil and hydrocarbon-based fluids
- Steel-and-canvas reinforcement — 3:1 standard or 4:1 premium
- Weather-resistant outer cover for outdoor and terminal installation
- Flange drilling to your project standard on request
- 2″ – 28″ bore, up to 20m per section
Air Suction & Delivery Hose
- Reinforced hose for suction and delivery of air and other non-corrosive gases
- Same pressure-rated construction as the liquid-handling range
- High-elasticity tube to handle pressure cycling without fatigue
- Steel-and-canvas reinforcement — 3:1 standard or 4:1 premium
- 2″ – 28″ bore, up to 20m per section
Each hose is built using the same high-strength reinforcement system. The inner tube compound is then tailored to the media being conveyed, ensuring optimum chemical compatibility and service life.

What's Holding Back the Pressure
Hover any layer in the diagram for what it does and why it's there.
Every rubber compound is rheometer-tested during production to ensure consistent curing. Mechanical and physical properties are then verified against the relevant international standards, with test results supplied in the shipment's Certificate of Analysis.
Hydrostatic Pressure
Tested to a minimum of 1.5× working pressure — confirms the hose holds before it's ever put under load on your site.
Vacuum / Negative Pressure
Confirms the wall won't collapse under suction duty, not just hold pressure on the discharge side.
Burst Pressure
Physically verified to 8″ bore at both 3:1 and 4:1 ratios; larger diameters qualified via hydrostatic and vacuum testing to the required design factor.
Rheometer — Cure Curve
Run on every batch to confirm consistent cure state before it ever leaves the factory.
Hardness (Shore A)
Verifies the durometer ordered is the durometer delivered, batch to batch.
Tensile Strength & Elongation
Confirms the compound holds together and flexes as specified under working load.
Abrasion Resistance
The core measure of how long an abrasion-duty tube actually lasts against cement, sand and slurry.
Chemical & Fluid Immersion
Confirms swell and degradation stay within spec for oil and process-fluid exposure.
Electrical Conductivity & Grounding
Confirms the hose safely dissipates static charge — critical for fuel, solvent and fine dry-bulk transfer where a spark is a genuine risk.
SGS Pre-Shipment Inspection Available on Request
Independent verification before your order leaves Thailand.
Full batch traceability
Back to the raw rubber lot, with test data available on request.
Certificate of Origin
Issued by Duratan as exporter of record. This supports preferential duty treatment for imports into Australia (TAFTA), New Zealand, Japan, China, South Korea and other Free Trade Agreement partner countries.
Fixed pricing, up to 24 months
Hedged against raw rubber, foreign exchange and freight volatility, so your budget doesn't move mid‑contract.
1‑year warranty
Across the full hose range.
Flange drilling on request
ANSI/ASME B16.5, EN 1092/DIN, AS 4087, PN10/PN16, TIS, or JIS — built to your project standard.
