XLPE Chemical Delivery Hose 16 Bar Overview

XLPE Chemical Delivery Hose 16 Bar is a softwall hose listed for delivery of a range of chemicals. Its published construction uses an XLPE tube, green EPDM blend cover, multiple layers of high-tensile synthetic cord and an embedded antistatic copper wire. Chemical-hose selection must be based on the exact chemical, concentration, temperature, pressure and complete assembly.

Published Hose Construction

• Tube: XLPE, described for aggressive-chemical resistance.
• Cover: green EPDM blend compound described as resistant to chemicals, abrasion and ozone.
• Reinforcement: multiple layers of high-tensile synthetic cord.
• Static-control feature: embedded antistatic copper wire.
• Published temperature range: -30°C to +93°C, with a published 120°C reference for 30 minutes.
• Published safety factor: 3:1.

Understanding the 16 Bar Product Designation

The 16 bar wording identifies the product range but does not automatically approve every hose size or assembled configuration for 16 bar service. Confirm the current size-specific pressure data, working pressure, pressure surges, duty cycle, fittings and assembly method.

The Lowest-Rated Component Governs

The complete assembly is limited by its lowest-rated hose, fitting, ferrule, clamp, flange, gasket, valve or adapter. Chemical compatibility and pressure capability must both be satisfied.

Chemical Compatibility Review

Provide the full chemical name, concentration, mixture composition, purity and current Safety Data Sheet. Compatibility must cover the XLPE tube, seals, gaskets, fittings and every wetted component. A broad statement about chemical resistance is not approval for every substance or mixture.

Process Conditions Can Change Compatibility

Temperature, concentration, contamination, exposure time and cleaning chemicals can change material behaviour. Batch transfer, continuous service and hose-draining conditions should be stated during the review.

Temperature and Short-Duration Exposure

Compare the published -30°C to +93°C range with the real fluid and ambient temperatures. The published 120°C for 30 minutes reference must be verified for the exact chemical, hose size, pressure and manufacturer conditions; it should not be treated as a continuous-service rating.

Static Electricity, Bonding and Continuity

Chemical transfer may create static electricity depending on the fluid and process. The embedded copper wire is a construction feature, but bonding, grounding and continuity requirements must be defined by the site risk assessment.

Test the Complete Assembly Where Required

If electrical continuity is required, confirm how the wire is terminated at both fittings and test the completed assembly using the specified method and acceptance criteria. Do not assume continuity from hose appearance alone.

End Connections and Installation:

Confirm hose bore, overall length, fitting or flange standard, material, sealing method and orientation. Every fitting and seal must be compatible with the chemical. Route the hose with adequate bend radius and support, away from sharp edges, crushing loads and excessive heat.

Inspection and Safe Handling

Before handling, stop the transfer, isolate the system, release trapped pressure and drain or decontaminate according to the chemical SDS and site procedure. Use the required personal protective equipment and trained personnel.

Remove the assembly from service if it shows swelling, softening, hardening, blistering, cracks, exposed reinforcement, leakage, damaged fittings or unusual discolouration. Do not improvise repairs on a chemical hose.

Information Required for an Engineering Review

• Exact chemical name, concentration, composition and SDS
• Normal and cleaning chemicals
• Working pressure, surge pressure and duty cycle
• Fluid and ambient temperature, including short-duration peaks
• Required hose bore and overall length
• Connection standard, size, material, seal and orientation
• Routing, bend, movement and abrasion conditions
• Grounding, continuity, testing and documentation requirements

Send these details to Advtech Engineering for a configuration review. Final suitability must be confirmed for the exact chemical and operating conditions before installation.
