Advantages and Disadvantages of Threaded Fittings
Threaded joints are among the oldest methods for connecting pipe systems. They are often applied in low-cost, noncritical systems, where vibration and extreme temperatures are unlikely. Specialized installation skills are not required.
Threaded fittings are vulnerable to fatigue damages and, therefore, should not be used in the transportation of hazardous materials. Additionally, leaking may occur as a result of rapid temperature changes.
