Can the Hydraulic hose for high temperatures EN 853 1SN/HT THERMAL be used continuously at +135Â°C and what precautions for air use above 17 bar (micro-perforation) are required?

Hydraulic hose for high temperatures EN 853 1SN/HT THERMAL Yes . the hoseâs specified continuous operating temperature is up to +135Â°C (with short-term tolerance to +150Â°C). However, for water and air the manufacturer limits the maximum operating temperature to +70Â°C; therefore continuous use of air at +135Â°C is not permitted. Precautions for air use above 17 bar: - Micro-perforation of the outer layer is required when the hose is used with air above 17 bar to relieve localized pressures and prevent outer-layer failure. - Ensure the hose is installed with adequate support and free from sharp bends, abrasion and heat sources that could accelerate degradation. - Use appropriate fittings and clamps rated for both the working pressure of the specific hose diameter (40â225 bar range) and the elevated temperature conditions applicable to air service (note: air temperature must not exceed +70Â°C per spec). - Implement regular inspection and maintenance: check for signs of micro-perforation wear, bulging, blistering, oil/ozone attack, or air leaks; replace immediately if any defects appear. - Follow manufacturer guidance and perform pressure testing in a controlled manner before service. In summary: do not use Hydraulic hose for high temperatures EN 853 1SN/HT THERMAL continuously at +135Â°C for air (limited to +70Â°C). For air above 17 bar, micro-perforation of the outer layer plus proper installation, fittings, inspections and adherence to manufacturer limits are required.

Is the Hydraulic hose for high temperatures EN 853 1SN/HT THERMAL suitable for steam or hot oil applications at +150Â°C temporarily?

Hydraulic hose for high temperatures EN 853 1SN/HT THERMAL: No - this hose is designed for hydraulic fluids up to +135Â°C continuous and only +150Â°C temporarily per specification, but it is not rated or recommended for steam or hot oil service at +150Â°C. Steam and hot oil have different pressures, temperatures, chemical and thermal degradation mechanisms; the hoseâs materials, braid and seals are not certified for steam exposure. Using it with steam or hot oil at +150Â°C risks rapid deterioration, loss of pressure integrity and safety hazards. For steam or continuous hot oil service at those temperatures, select hoses specifically approved for steam/hot-oil applications with appropriate temperature and pressure ratings.

What are the recommended storage and installation guidelines for Hydraulic hose for high temperatures EN 853 1SN/HT THERMAL to ensure its 300,000 impulse cycle life?

Hydraulic hose for high temperatures EN 853 1SN/HT THERMAL. Recommended storage and installation guidelines to ensure 300,000 impulse cycle life Storage - Store hoses in a cool, dry, well-ventilated area away from direct sunlight, heat sources and ozone-generating equipment. - Maintain ambient temperature between +5Â°C and +25Â°C when possible; avoid prolonged exposure above +40Â°C. - Keep hoses coiled on pallets or racks with large-radius bends; do not stack heavy loads on top. - Protect ends with caps to prevent contamination and ingress of dust, moisture or chemicals. - Avoid contact with solvents, fuels, greases and sharp objects; keep away from corrosive substances. - Use first-in, first-out rotation; mark manufacture/receipt date and do not exceed recommended storage life per supplier recommendations. Handling and preparation - Inspect hose visually for cuts, kinks, abrasion, contamination or other damage before installation. - Do not bend hose below its minimum bend radius; follow manufacturerâs specified bend radius for each diameter. - Cut hose ends squarely with appropriate tools; remove loose particles and metallic burrs. - Use fittings and crimping tools specified for EN 853 1SN/HT THERMAL; ensure correct ferrule and coupling sizes and crimp parameters. - Avoid twisting the hose when fitting couplings; maintain alignment to prevent torsion stress. Installation - Install with smooth routing, avoiding sharp bends, tight clamps and areas of potential abrasion. Use protective sleeves or spiral wrap where rubbing or movement may occur. - Leave adequate slack to accommodate thermal expansion and dynamic movement; secure hose with clamps or guides that do not compress or chafe the outer cover. - For systems carrying water or air, observe maximum operating temperature +70Â°C. For air applications above 17 bar, ensure outer layer micro-perforation has been applied per specification. - Ensure working pressure of the system matches hose rating (40â225 bar depending on diameter) with adequate safety margin; avoid pressure spikes and water hammer. - Protect hose from exposure to temperatures above +135Â°C for prolonged periods; temporary excursions to +150Â°C are acceptable only per duty-cycle limits and with system validation. Commissioning and testing - After installation, perform a low-pressure leak test, then gradually bring to operating pressure while checking fittings and hose routing. - Perform impulse testing or validation if required by the application to confirm assembly integrity. Maintenance - Periodically inspect hoses in service for abrasion, cuts, hardening, softening, bulges or leakage. Replace immediately if damage or significant wear is found. - Monitor operating temperature and pressure excursions; log duty cycles if required to track remaining life toward the confirmed 300,000 impulse cycles. - Ensure clamps, fittings and supports remain secure and free from corrosion. Following these storage, handling and installation practices will help realize the confirmed 300,000 impulse cycle life of Hydraulic hose for high temperatures EN 853 1SN/HT THERMAL.
