Heavy Duty Air Hose 20 Bar

Heavy Duty Air Hose 20 Bar Overview

Heavy Duty Air Hose 20 Bar is listed for transfer of compressed air and water in mining, shipyard, civil and building-industry duties. The published construction uses an SBR blend tube, yellow EPDM blend cover and multiple layers of high-tensile synthetic cord. Final selection must match the hose size, pressure cycle, medium, temperature, fittings and actual site conditions.

Published Hose Construction

• Tube: black SBR blend compound described as resistant to oil mist.
• Cover: yellow EPDM blend compound described as resistant to abrasion and weather.
• Reinforcement: multiple layers of high-tensile synthetic cord.
• Published temperature range: -25°C to +85°C.
• Published safety factor: 3:1.

Understanding the 20 Bar Product Designation

The 20 bar wording identifies the product range but does not automatically approve every hose size or assembled configuration for 20 bar service. Confirm the current size-specific pressure data, compressor settings, possible pressure spikes, duty cycle and assembly method.

The Complete Assembly Determines the Limit

The allowable working pressure is governed by the lowest-rated hose, coupling, clamp, ferrule, valve or adapter. Whip restraints and other safeguards do not increase the pressure rating of an assembly.

Air, Water and Media Review

State whether the hose will carry compressed air, water or another approved medium, including moisture, oil mist and any additives. Compatibility must cover the tube, seals, fittings and all wetted components.

Not Automatically Approved for Breathing Air

A general compressed-air hose must not be used for breathing-air supply unless the exact hose, assembly and complete system have been specifically approved for that service.

Temperature and Environmental Conditions

Compare the published -25°C to +85°C range with both medium and ambient temperatures. Consider compressor discharge heat, sunlight, weather, oil mist, abrasion and nearby hot surfaces. Confirm whether the operating temperature changes the allowable pressure.

Connections and Assembly Details

Confirm hose bore, overall length, coupling type, thread or flange standard, fitting material, sealing method and orientation. Use a verified retention method suitable for the hose and fitting combination; similar-looking couplings may not be interchangeable.

Control Hose-Whip Risk

Pressurised air stores energy. Where required by the site risk assessment, use correctly selected restraints, guards or isolation arrangements. Keep personnel clear during initial pressurisation and inspect for abnormal movement or leakage.

Routing, Inspection and Safe Handling

Route the hose away from sharp edges, vehicle traffic, hot surfaces and areas where movement could create a trip or whip hazard. Avoid twist, kinks, crushing and excessive bend. Support the hose without creating strain at the fittings.

Before handling, shut off and isolate the supply and release trapped pressure. Remove the assembly from service if it shows cuts, blistering, exposed reinforcement, soft spots, hardening, leakage, damaged fittings or unusual deformation.

Information Required for an Engineering Review

• Medium and any oil, moisture or additives present
• Working pressure, pressure spikes and compressor settings
• Duty cycle and flow requirement
• Medium and ambient temperature range
• Required hose bore and overall length
• Connection type, size, material and orientation
• Routing, bend, movement, abrasion and weather exposure
• Required restraints, testing, identification or documentation

Send these details to Advtech Engineering for a configuration review. Confirm the exact hose and complete assembly against the real operating conditions before installation.
