What is the maximum temperature that a metal hose made of 20# steel with DN20\PN2.0 specifications can withstand?
Temperature generally has little impact on pressure resistance; it is only related to the material used in the hose. The higher the temperature, the lower the allowable stress value of the material, and consequently the lower the pressure resistance as well； It mainly depends on the actual material of your flexible metal hose; the operating temperature for carbon steel is roughly around 0-200°C ； Stainless steel can be used at temperatures around -162 to 200°C.
