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.

The revision of this standard was attempted several times, and the course of revision id described. Easy to apply in field testing when used portable set. Non-relevant signal and noise are disturbed evaluation. Comparatively, cost for testing is higher zz others. Cost for testing is lower than other methods.

Information of flaw’s height, spreading along to wall thickness direction can be got. Coupling medium must be applied on surface of subjects for testing Generally, not evaluate the kind of discontinuity. High speed test is available. Discontinuities with several direction can be detected at once. Revised standard, JIS Z Magnetic field is made by Electric AC Yoke. Thinner coating covered a surface discontinuity is not disturbed for detecting by this method.

MT Advantage Cost for testing is lower than other methods. 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 enumerated.

Round uis discontinuity can be detected easily. Careful application according to a test procedure is required for getting proper test results.

Easy for detecting a plain type discontinuity.

PT Advantage Easy to apply in field testing when used portable set. This is a method to send ultrasounds to the tested surface and receive the signal of subject flaws by a Normal transducer positioned perpendicular.

Round type discontinuity is difficult for detection. Cost for testing is lower than RT Radiographic Testing. Search coil works in tubes without contact and corresponds quickly to the applied test frequency. Close Go to Workspace. Easy to evaluate by visible indication appeared on tested surface. Most economical method for tube inspection of a heat exchanger to detect local corrosion and erosion.

The basic policy of the revision is the adoption of the latest technology of radiography, the compatibility with the ISO standards as far as possible and the standardization of testing methods and technical matters which are not standardized. Test is applied on ferromagnetic materials only. Angle Beam Method for Flaw detection Share mode ultrasound is sent with a angle, 45, 60, 70 degree, and operator received a signal from flaw.

For this test, the electromagnetic phenomenon is used and any coupling medium is not necessary. Easy for detecting a superficial discontinuity. Results 1 – 1 of 1. The main points of jjs revision in the standard proper and the appendices for the cases of steel plate welded joints, the circumferential joints of steel pipes, the T-shaped joints of steel plates and the method of classifying flaw images by radiographs are described.

Weak Point Non-relevant signal and noise are disturbed evaluation.

JIS Z – Methods of radiographic examination for welded joints in steel (FOREIGN STANDARD)

Weak Point Limited to ferromagnetic materials. UT Advantage Easy for detecting a plain type discontinuity. Required to remove the coating and foreign material inside a flaw completely before testing. Not disturbed to the thickness 31004 thicker subjects. Thicker coating must be removed before testing. Not applicable to fillet weld to top Test is applied on ferromagnetic materials only.

Invisible fine discontinuity can be detected by a magnified indication with surpass contrast on proper background. Skilled technician is required to conduct testing.

Post-Cleaning is necessary for rotating equipments to remove the particle.

JIS Z 3104:1995 English Edition

Easy for evaluating the kind of discontinuity from test results. Local corrosion occurred on opposite side can be located and the remained wall thickness can be read by continuous searching. Please provide a name for this query: No electric power is required except for lighting in dark room.

Not applicable to fillet weld. Publication Year Publication Year. V Eddy Current Testing: Weak Point Required to remove the coating and foreign material inside a flaw completely before testing.

ET Advantage High speed test is available. Easy 1304 handling with portable devices. Test result is remained as persuasive record. Surface and near surface discontinuity can be detected. Surface condition is affected to test results. Share mode ultrasound is sent with specified angle, 45, 60, 70 degree, and operator received a signal from flaw.
