Can STEAM STAR® Delivery Hose for Saturated Steam, 18 BAR be used continuously at +230°C peak temperatures, and what precautions are required?

STEAM STAR® Delivery Hose for Saturated Steam, 18 BAR is rated for continuous operation up to +210°C and can tolerate short peaks to +230°C. Continuous use at the +230°C peak is not recommended—+230°C is a transient limit the construction can withstand briefly. For safe operation at or near peak temperatures follow these precautions: - Use only with the specified screw-on steam fittings matched to the hose diameter and wall thickness to avoid failure at connections. - Avoid prolonged continuous exposure at +230°C; keep normal working temperature ≤ +210°C. - After each use, fully empty the hose of steam to prevent condensate buildup, which accelerates wear and reduces life at high temperatures. - Monitor for signs of overheating, external damage or loss of flexibility; inspect fittings, braids and inner rubber regularly. - Ensure installation and duty cycles allow cooling periods so the hose does not remain at peak temperature continuously. Following these measures will maximize safety and service life when operating near the hose’s temperature limits.

Can STEAM STAR® Delivery Hose for Saturated Steam, 18 BAR be used with condensate-return systems, and what maintenance prevents condensate-related damage?

Yes — STEAM STAR® Delivery Hose for Saturated Steam, 18 BAR can be used with condensate-return systems, provided installation follows proper steam-practice and matches the hose to system fittings and pressures. Because the hose is built for saturated steam (EPDM inner layer, double steel braid, 18 bar rating, -40°C to +210°C operational range, peaks to +230°C), it tolerates the temperatures and pressures typical of condensate-return service. Key maintenance to prevent condensate-related damage: - Drain and empty the hose after each use to remove retained condensate and avoid internal water hammer or prolonged exposure of the rubber to standing condensate. - Install correct slope and drainage points so condensate naturally returns to the collection system; avoid low spots where water can collect. - Use the specified screw-on steam fittings that match diameter and wall thickness to ensure leak-free connections and prevent condensate intrusion at joints. - Regularly inspect the inner EPDM and outer jacket for signs of swelling, blistering, abrasion or embrittlement; replace hose if damage or deformation from condensate is detected. - Monitor for repeated thermal cycling and purge condensate during shutdowns to minimize fatigue. Following these practices preserves hose integrity and ensures safe, reliable performance in condensate-return applications.
