For oil, naterual gas, petrolem, chemical and other special industry projects, testing material is necessary, in order to guarrantee the safe of the pipeline.
Ultrasonic Testing (UT), Radiographic Testing (RT), Magnetic particle Testing (MT), Penetrant Testing (PT), Eddy current Testing (ET) and Component detection are common for butt weld pipe fittings and forged flanges.
What is UT Test?
Ultrasonic testing (UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion.
Ultrasonic testing is often performed on steel and other metals and alloys, though it can also be used on concrete, wood, and composites, albeit with less resolution. It is used in many industries including steel and aluminum construction, metallurgy, manufacturing, aerospace, automotive, and other transportation sectors.
How UT Test applied in forged flanges?
As a manufacturer of butt weld pipes fittings and forged flanges, the UT is often used to test whether there is a gas cavity, Slag inclusion, Incomplete welding, Incomplete fusion, crack, etc.
