Non-destructive testing (NDT) methods are used to evaluate the integrity of pressure equipment without damaging or altering the equipment. Here are some of the most common NDT methods used for pressure equipment: 1. Ultrasonic testing - Ultrasonic testing uses high-frequency sound waves to detect internal defects or flaws in pressure equipment, such as cracks or voids. This method is commonly used for testing welds, piping, and pressure vessels. 2. Radiographic testing - Radiographic testing uses X-rays or gamma rays to detect internal defects or flaws in pressure equipment. This method is commonly used for testing welds, piping, and pressure vessels. [...]

What are some common industry standards for pressure testing?
