In high-pressure chemical transfer, three problems keep showing up on site: corrosion leaks, burst hoses, and failures caused by temperature swings. The resulting downtime hits hard, and the safety risks are not something any plant can afford to ignore. Hengshui Zhehan’sHigh-Pressure Chemical Conveying Hose combines a PTFE inner liner with a multi-layer spiral-wound steel wire reinforcement structure. It handles aggressive chemicals, stays stable under high pressure, and works across a wide temperature band from -40 °C to +120 °C. If you’re looking to solve fluid transfer headaches with one reliable hose — and stop patching problems that shouldn’t exist in the first place — get in touch. We’re set up to provide technical advice, material recommendations, and a tailored quote for your operating conditions.
We focus on providing a complete high-pressure chemical transfer hose solution — not just a length of hose. The priority is to eliminate corrosion leakage, pressure bursts, and temperature-related failures where aggressive media move under tough conditions. By selecting the right PTFE liner and a properly specified steel wire reinforcement, we help plants avoid the costly cycle of hose replacement, unplanned shutdowns, and environmental or safety incidents. Backed by proven materials and precise manufacturing, the hose delivers a longer service life, less frequent maintenance, and a lower total cost of ownership. It’s a practical way to keep high-pressure chemical operations running safely and efficiently.
Petrochemical: High-pressure transfer of crude oil, refined products, acids, alkalis, and high-temperature cracking media.
Fine chemical: Conveying organic solvents, intermediates, strong oxidizers, and other aggressive process fluids.
Pharmaceutical and biotech: High-purity reagent transfer, fermentation broths, and sterile acid/alkali cleaning solutions under pressure.
New energy: Lithium battery electrolyte, photovoltaic chemicals, and energy storage media in high-pressure lines.
Environmental wastewater treatment: High-acid and high-alkali wastewater, chemical reagents, and sludge transfer at pressure.
Mining and metallurgy: Slurries, acid pickling waste, and high-temperature smelting media in high-pressure hose lines.
The liner resists strong acids, alkalis, organic solvents, and strong oxidizers. In corrosive service, service life is typically three times longer than conventional rubber-lined hose, and the liner is compatible with roughly 98% of common industrial chemicals.
Working pressures range from 10 MPa to 35 MPa, with a burst pressure at least 4 times the working pressure. The structure handles pressure surges and pulsation well, keeping the hose stable and safe under high-pressure chemical transfer.
The hose remains stable from -40 °C to 120 °C. It does not deform in high heat or become brittle in extreme cold, making it suitable for alternating hot-and-cold process conditions.
The steel wire spiral plus a specially compounded rubber layer give the hose a small bend radius and easy routing. It can withstand around 100,000 impulse cycles, resisting vibration and displacement fatigue in dynamic applications.
Made from an EPDM or CSM compound, the cover resists ozone, ultraviolet exposure, and abrasion. Under outdoor or harsh plant conditions, the expected cover life is five years or more, helping keep overall hose performance stable over the long term.

Never exceed the rated working pressure or temperature. During installation, avoid twisting or sharp bends; keep the minimum bend radius at least 5 times the inner diameter.
Keep the hose away from open flames, high-temperature heat sources, and sharp objects that can cut the cover. Regularly inspect the hose body, fittings, and pressure condition, and take it out of service immediately if any abnormality is found.
Do not allow the hose to remain in contact with incompatible fluids for extended periods. Store in a dry, cool, ventilated area away from sunlight, moisture, and heavy loads.
Handle carefully during transport and installation — avoid hard impacts. Under typical operating conditions, we recommend a replacement interval of 1–2 years, adjusted based on actual service conditions and inspection results.
Q: What chemicals can the PTFE-lined hose handle?
A: The PTFE liner offers near-universal chemical resistance. It can safely convey strong acids, strong alkalis, organic solvents, and strong oxidizers. If you provide us with a list of your process chemicals, concentrations, and temperatures, we can confirm compatibility and point out any special considerations.
Q: Can I order a short sample length to test before placing a bulk order?
A: Yes. We support small trial orders so you can verify chemical compatibility and pressure performance under your actual conditions. Just tell us the diameter and length you need for testing.
Q: What is the minimum order quantity?
A: For standard sizes, the regular MOQ is 100 meters. However, we are flexible with smaller first orders for evaluation and project sampling. Let us know your requirements, and we’ll work out a practical initial shipment.
Q: Do you provide complete hose assemblies with end fittings?
A: Yes. We can supply the hose assembled with flanges, threaded ends, quick couplings, or other connection types to match your pipework. We also offer OEM branding and label printing.
Q: What warranty do you provide?
A: Every hose undergoes strict factory inspection before shipment. We provide a 12-month warranty under normal usage conditions. If a quality issue arises, we will arrange a replacement at no charge.
Q: How do I get a quote or request technical support?
A: Contact us directly by phone or online inquiry. Share your required inner diameter, working pressure, length per assembly, connection type, and the chemicals you are handling. Our team will provide a quotation, lead time, and technical recommendations — usually within one working day. Hengshui Zhehan focuses on high-pressure chemical hose R&D and manufacturing, and we’re ready to help you find the right hose for the job.
