Soldered joints shall never be used on systems operating above _____ degrees

Soldered joints are not suitable for systems operating above 250 degrees Fahrenheit due to the risk of the solder melting and compromising the integrity of the joint. Solder is an alloy that is typically used at lower temperatures, and its melting point is significantly lower than that of the base metals typically used in piping systems, such as copper or brass.

When the temperature in a system exceeds 250 degrees, the strength and reliability of soldered joints can be adversely affected, leading to potential leaks or failures in the system. This is particularly critical in applications involving hot fluids or gases, where maintaining a secure and leak-free connection is essential for safety and operational efficiency.

Therefore, for applications operating at high temperatures, it is recommended to use mechanical joints or welding methods that can withstand the elevated stresses and resist thermal degradation, ensuring the longevity and safety of the piping system.
