In chemical processing and environmental treatment applications, strong acids, alkalis, and solvents can quickly attack standard hoses — leading to frequent failures, leaks, and costly unplanned downtime. Hengshui Zhehan’s Corrosion-Resistant Industrial Hoses combine a specialty rubber lining with steel wire reinforcement to handle aggressive media at pressure, improving service life by up to 60% compared to ordinary hose. If you need a hose that matches your specific chemical and operating conditions, reach out — we’ll help you get the right solution, not just a commodity product.
Designed to solve the hardest corrosive media transfer challenges, this Chemical-Resistant Industrial Hose helps eliminate leaks and the safety risks that come with them. With a working temperature range of -40 °C to +120 °C and pressure ratings from 0.5 MPa to 40 MPa, it significantly cuts replacement frequency and process downtime. The objective is straightforward: reliable, continuous operation in chemical, environmental, and other process industries — delivering genuine long-term value, not short-term savings at the cost of reliability.
Chemical industry: Conveying corrosive materials such as 98% sulfuric acid, 30% sodium hydroxide, and various organic solvents.
Environmental water treatment: Wastewater processing, flue gas desulfurization, and acid/alkali waste liquid transfer lines.
Pharmaceutical industry: High-purity liquid pharmaceutical, reagent, and solvent transfer, suited for clean production requirements.
Food and beverage: Food-grade acids, citric acid, and ethanol transfer — safe and non-toxic when the correct inner tube material is selected.
Metallurgy and mining: Acid pickling, electroplating, slurry, and other corrosive fluid transfer.
New energy: Battery electrolyte and acid/alkali cleaning fluid delivery systems.
The inner tube is available in EPDM, PTFE, or FKM depending on the chemical environment. It resists 98% strong acids and 40% strong alkalis. Under ISO 1817 immersion testing, volume change is typically ≤10%, confirming excellent chemical compatibility.
Multiple layers of steel wire braid or spiral provide uniform strength. Working pressure can reach 40 MPa, with burst pressure at least 3 times the working pressure. The hose handles pressure surges and pulsation without bulging or bursting.
The hose operates stably from -40 °C to +120 °C, and a special formulation allows short-term exposure up to 150 °C. This covers everything from cold outdoor installations to high-temperature process fluids.
The EPDM outer cover resists UV, ozone, and mechanical abrasion. After 500 hours of QUV accelerated weathering, the cover shows no cracking. Expected service life under normal conditions is 5,000 hours or more.
Minimum bend radius is 5 to 8 times the hose diameter, so the hose fits into tight pipe galleries and equipment layouts without collapsing. Installation is straightforward, and the lower replacement frequency keeps maintenance costs under control.

Never exceed the rated working pressure or temperature. During installation, avoid twisting or excessively tight bends. Check fitting tightness regularly to prevent leaks of hazardous media.
Do not leave the hose exposed to direct sunlight, oil, or standing chemicals for long periods. Store in a cool, dry place away from heat sources. After use, flush the hose to remove residual chemicals and reduce internal corrosion. Routine care like this directly extends the time between replacements.
Q: What is the minimum order quantity?
A: The regular MOQ is 100 meters, but we also support smaller trial quantities so you can test the hose with your actual media before committing to a large order. Tell us what you need, and we’ll work out a practical first shipment.
Q: Can you customize the hose?
A: Yes. We customize inner diameter, length, working pressure, fitting type, and material selection. OEM service is available to match your process connections exactly — we regularly supply custom-built hose assemblies to chemical plants and equipment builders.
Q: What warranty do you provide?
A: We provide a 12-month warranty. If a quality defect occurs under proper usage conditions, we will arrange a free replacement.
Q: How do I know which inner tube material is right for my chemicals?
A: We offer three main inner tube materials. EPDM works well with many acids, alkalis, and polar solvents. PTFE provides near-universal chemical resistance and is often chosen when high purity is required. FKM is suited for aggressive solvents and high-temperature applications. Send us your chemical list with concentrations and operating temperatures, and we will provide a compatibility recommendation backed by available test data.
Q: Can you provide chemical resistance test reports?
A: Yes. We can supply test data such as ISO 1817 immersion test results and other relevant material test reports upon request, so you can review performance before ordering.
Q: How can I get a quotation, a sample, or technical support?
A: Simply contact us directly. Hengshui Zhehan has focused on chemical-resistant hose R&D and manufacturing for years. We can send product samples, detailed datasheets, and application advice to help you select the right hose. Just let us know your operating conditions and we will respond with a specific, practical recommendation.
