What is the limit for fittings constructed of Cast Iron?

Cast iron fittings are often used in various applications due to their strength and durability. However, they have specific limitations regarding the pressure and temperature they can safely handle.

The correct choice indicates that the limit for fittings constructed of cast iron is 1700 kPa and a temperature of 230°C. This answer reflects the operational parameters of cast iron fittings accurately, aligning with industry standards and guidelines. Cast iron is able to withstand relatively high pressures and temperatures, but 1700 kPa is generally regarded as the upper limit for safety in many applications. Simultaneously, the temperature limit of 230°C takes into consideration the material's susceptibility to deterioration or failure under prolonged exposure to high temperatures.

Choosing other options suggests a misunderstanding of these limits. For example, the first option lists limits significantly lower than what is considered safe for cast iron, indicating that it could lead to malfunction or breakdown. The second option also features a temperature that is less than what cast iron can typically handle, and the third option specifies extreme values that are unrealistic, as they exceed typical engineering standards for cast iron materials.

Understanding these parameters is essential for maintaining the integrity and safety of systems using cast iron fittings, thereby ensuring efficient and reliable operation.
