UHMWPE Chemical Discharge Hose 250Psi

Product Overview

The UHMWPE Chemical Discharge Hose 250Psi is a premium-grade industrial hose engineered for the safe transfer of aggressive chemicals and solvents in plant operations and tank truck applications. As a leading manufacturer and supplier based in china, we provide a clear definition of this product: a lightweight, non-corrosive hose that combines a UHMWPE inner tube with EPDM rubber cover, delivering exceptional chemical resistance at a working pressure of 250Psi. Unlike standard rubber hose, this construction prevents swelling, leaching, and premature failure when handling acids, alkalis, and solvents.

The core structure consists of three layers: a white, smooth Ultra-High Molecular Weight Polyethylene (UHMWPE) inner tube, multi-plies of high-strength synthetic fabric for reinforcement, and an EPDM outer cover that is resistant to chemicals, weathering, and ozone. The cover is available in blue or green wrapped finish, providing excellent visibility and professional appearance in industrial environments.

Key performance parameters include a maximum working pressure of 17 bar (250Psi), a minimum bursting pressure of 51 bar (750Psi) – providing a 3:1 safety factor – and an exceptional temperature range from -40°C (-72°F) to +120°C (+248°F). This temperature capability exceeds many standard chemical hoses, making it suitable for both cryogenic and high-temperature chemical transfer.

Core advantages of this solution include: 1) superior chemical compatibility with over 95% of industrial chemicals, 2) a smooth bore that maximizes flow rates and prevents residue buildup, 3) lightweight construction that reduces operator fatigue during tank truck loading/unloading, and 4) excellent flexibility even at low temperatures. This hose solves the common pain points of chemical plant engineers: frequent rubber hose failures, media contamination from dissolved rubber particles, and high replacement cost.

Primary applications include in-plant chemical transfer, tank truck loading and unloading systems, industrial waste handling, mining chemical injection, and agricultural chemical spraying. The service team at our factory provides full support including custom hose assembly with crimped fittings, reusable fittings, adapters, flanges, and protective sleeves or guards for abrasive environments.

Structure and Materials

Layer-by-Layer Construction

• Inner Tube (UHMWPE): White, smooth Ultra High Molecular Weight Polyethylene. This material is chemically inert, providing exceptional resistance to nearly all industrial chemicals. The smooth surface ensures minimal pressure drop and prevents media adhesion, making cleaning fast and complete.
• Reinforcement Layer: Multi-plies of high-strength synthetic fabric. This textile reinforcement provides the structural integrity to handle the 250Psi working pressure while maintaining flexibility. Unlike Wire Braided Hose or Wire Spiral Hose (which are designed for hydraulic oil High Pressure Hose applications), this fabric reinforcement is optimized for chemical transfer where kinking resistance and flexibility are priorities.
• Outer Cover: EPDM rubber resistant to chemicals, weathering, and ozone. Available in blue or green wrapped finish. This cover protects the reinforcement from external damage, UV degradation, and chemical splashes, ensuring a long operational life even in harsh outdoor environments.

Why UHMWPE Over Rubber or PTFE?

Verdict: For aggressive chemical transfer where long life and safety are critical, the UHMWPE Chemical Discharge Hose 250Psi offers the best balance of price and performance. It significantly outlasts standard rubber hose and is more flexible and affordable than PTFE.

Application Industries

This chemical discharge hose is specified by engineers worldwide for its reliability, safety, and long service life.

Brand and Quality Assurance

As a trusted wholesaler and exporter with years of experience in the industrial hose industry, our quality commitment goes beyond standard testing.

Our Manufacturing & Quality Process

1. Raw Material Incoming Inspection: Every batch of UHMWPE tube compound, synthetic fabric, and EPDM rubber is tested for hardness, tensile strength, and specific gravity before entering production.
2. Extrusion Control: The UHMWPE tube is extruded with precise wall thickness monitoring. Any deviation beyond tolerance triggers immediate correction.
3. Reinforcement Winding: Multi-plies of synthetic fabric are wound at exact angles to achieve the 250Psi working pressure rating with a 3:1 safety factor.
4. Cover Extrusion & Wrapping: The EPDM cover is applied in blue or green wrapped finish, providing excellent chemical and weather resistance.
5. Curing (Vulcanization): The assembled hose is cured in large autoclaves to bond all layers permanently.
6. 100% Visual & Dimensional Inspection: Every meter is inspected before coiling. Outside diameter, concentricity, and surface finish are verified.
7. Hydrostatic Proof Testing: Representative samples from each batch are tested to 375Psi to verify integrity.

Installation, Operation, and Maintenance Guide

Installation Best Practices

• Minimum Bend Radius: Do not exceed the recommended bend radius to prevent kinking and reinforcement damage.
• Use Protective Guards: Where the hose passes over sharp edges or where vehicles may run over it, use protective sleeves or guards.
• Fitting Attachment: For crimped fittings, ensure crimping dies match the hose specification. For reusable fittings, follow torque specifications precisely.
• Support Heavy Lengths: For long runs or large diameters (4″, 6″), use hose supports to prevent sagging and stress on fittings.

Operation Guidelines

• Pressure Limits: Never exceed 250Psi working pressure. Pressure spikes above 375Psi can cause premature failure.
• Temperature Limits: Operation within -40°C to +120°C is safe. Exceeding these limits will degrade the UHMWPE tube or EPDM cover.
• Chemical Compatibility: While UHMWPE resists most chemicals, always verify compatibility with your specific fluid, especially for concentrated oxidizing acids.

Maintenance & Inspection

• Visual Inspection Before Each Use: Check for cuts, abrasions, bulges, or exposed reinforcement.
• Check Fittings: Ensure crimped fittings or reusable fittings are tight and leak-free.
• Clean After Use: Flush the hose thoroughly after each chemical transfer, especially if the hose will be stored.
• Storage: Store indoors, away from ozone sources (electric motors, welding equipment), extreme heat, and direct sunlight. Coil loosely on a rack.

When to Replace

Replace the UHMWPE Chemical Discharge Hose 250Psi immediately if you observe:

• Exposed reinforcement fabric
• Hard or brittle sections (indicates chemical attack or heat aging)
• Soft or bulging areas
• Leaking fittings or damaged adapters
• The hose fails pressure testing
