Is ESSEN LLÂ® cooling water suction and discharge hose safe for short-term splashes of molten metal and exposure to external temperatures up to +530Â°C?

Yes. ESSEN LLÂ® cooling water suction and discharge hose is safe for short-term splashes of molten metal and for exposure to external temperatures up to +530Â°C. The hose is specifically designed for foundries and smelters: it features a glass-fiber outer covering that withstands thermal radiation up to +530Â°C and is explicitly described as resistant to short-term splashes of molten hot metal. Internally it has SBR rubber, synthetic cord and steel spiral reinforcement, and an EPDM/glass-fiber outer layer, making it suitable for cooling systems and water installations located close to metallurgical furnaces. Note that the continuous operating temperature range of the hose is â40Â°C to +70Â°C (internal), with external temperatures tolerated up to +530Â°C, and its working pressure is 10 bar with vacuum rating 0.9 bar.

Can ESSEN LLÂ® cooling water suction and discharge hose be used continuously near metallurgical furnaces at +70Â°C internal temperature?

Yes. ESSEN LLÂ® cooling water suction and discharge hose is designed for continuous operation with internal temperatures up to +70Â°C (operating range -40Â°C to +70Â°C). Its black SBR rubber inner layer, synthetic cord/steel spiral reinforcement and EPDM/glass-fiber outer cover make it suitable for cooling water systems near metallurgical furnaces. The glass fiber outer covering provides protection against thermal radiation up to +530Â°C and short-term splashes of molten metal, and the hose is particularly recommended for water installations close to furnaces. Working pressure 10 bar, vacuum 0.9 bar.

Can ESSEN LLÂ® cooling water suction and discharge hose withstand suction/vacuum conditions down to 0.9 bar?

Yes. The ESSEN LLÂ® cooling water suction and discharge hose is vacuum-resistant and rated for vacuum conditions down to 0.9 bar (relative), so it can withstand suction/vacuum levels to that value. Its constructionâblack SBR inner layer, synthetic cord and steel spiral reinforcement, and EPDM/glass-fiber outer layerâsupports use in cooling systems near high heat sources and metallurgical furnaces, with working pressure 10 bar and operating temperatures â40Â°C to +70Â°C (external heat resistance up to +530Â°C).
