Post-Cleaning is necessary for rotating equipments to remove the particle. Thinner coating covered a surface discontinuity is not disturbed for detecting by this method.
Non-Destructive Testing | SANKI MARINE SERVICE INC.
Video Scope Video Scope. At last, this revised standard was instituted on February 1, by investigating the present status in Japan and foreign countries by the cooperation of the related organizations and experts, and considering the compatibility with the international standards, based on the WES standards which are jiis.
Not applicable to fillet weld. No electric power is required except for lighting in dark room. Angle Beam Method for Flaw detection Share mode ultrasound is sent with specified angle, 45, 60, 70 degree, and operator received a signal from flaw.

The constitution of the standard is s. Cost for testing is lower than RT Radiographic Testing. Generally, qualitative analysis with reference artificial flaws. High speed test is available.
Test result is remained as persuasive record. V Eddy Nis Testing: Limited to ferromagnetic materials. Temperature and humidity must be essential for testing. V Magnetic Particle Testing: Plain type discontinuity like a crack, is not detected when the face has an angle usually over 15 degree to exposure direction of RT.

Revised standard, JIS Z Careful application according to a test procedure jos required for getting proper test results. Results 1 – 1 of 1. MT Advantage Cost for testing is lower than other methods. Cost for testing is lower than other methods. Search coil works in tubes without contact and corresponds quickly to the applied test frequency.
PT Advantage Easy to apply in field testing when used portable set. Local x occurred on opposite side can be located and the remained wall thickness can be read by continuous searching.
Ultrasonic transducer inserted into a tube can read the degree wall thickness via a rotating mirror attached to water turbine that is worked by pressure water. Comparatively, cost for testing is higher than others. Reference Number Reference Number. Easy for detecting a superficial discontinuity. Thicker coating must be removed before testing.
Share mode ultrasound is sent with specified angle, 45, 60, 70 degree, and operator received a signal from flaw. Weak Point Surface condition is affected to test results. 31104
Easy to evaluate by visible indication appeared on tested surface. This is a method to send ultrasounds to the tested surface and receive the signal of subject flaws by a Normal transducer positioned perpendicular. Required to remove the coating and foreign material inside a flaw completely before testing.
Coupling medium must be applied on surface of subjects for testing Generally, not evaluate the kind of discontinuity. Invisible fine discontinuity can be detected by a magnified indication with surpass contrast on proper background.
Easy to apply in field testing when used portable set. For this test, the electromagnetic phenomenon is used and any coupling medium is not necessary. Magnetic field 3014 made by Electric AC Yoke. Non-relevant signal and noise are disturbed evaluation.
Weak Point Limited to ferromagnetic materials. Round type discontinuity can be detected easily. Weak Point Accessibility for both side of test object is required. Round type discontinuity is difficult for detection. Magnetizing with perpendicular two direction is necessary for detection of each discontinuity.
Weak Point Required to remove the coating and foreign material inside a flaw completely before testing. Get permanent URL for this record. UT Advantage Easy for detecting a plain type discontinuity.
