Oct 14, 2004 · Ultrasonic pipe testing can provide solid, irrefutable evidence of a suspected corrosion problem, or document that a piping system has fulfilled its useful service life and is in need of replacement. At the high cost associated with any capital piping replacement, an ultrasound report will provide the hard documentation necessary to move the CN101710101A - Ultrasonic testing method for steel pipe The invention relates to an ultrasonic testing method for steel pipe void, which comprises the following steps of:confirming a tested fracture surface of each steel pipe and arranging a plurality of survey lines on the surface of each steel pipe in a uniform distribution way; knocking each survey line on each fracture surface of arch ribs by a small hammer, preliminarily judging the
Common non-destructive testing methods for steel pipes include:radiographic testing, magnetic particle testing, penetrant testing, ultrasonic testing, and eddy current testing. 1. Radiographic testing (RT) Ultrasonic testing (UT) This method uses ultrasonic vibration to find internal (or surface) defects in materials or parts. Non-destructive Testing Methods for Steel Pipes - OilVoiceIn order to meet the market demand, there is a high requirement for the quality inspection of steel pipes. The structure, state and performance of the inner or surface of the steel pipe are inspected by means of non-destructive testing to determine whether the steel pipe is qualified. This test does not damage the steel pipe to be tested. Nondestructive Testing Standards - ASTM InternationalStandard Practice for Ultrasonic Testing of Metal Pipe and Tubing:E273 - 15:Standard Practice for Ultrasonic Testing of the Weld Zone of Welded Pipe and Tubing:E317 - 16:Standard Practice for Evaluating Performance Characteristics of Ultrasonic Pulse-Echo Testing Instruments and Systems without the Use of Electronic Measurement Instruments
Standard Practice for Ultrasonic Testing of Metal Pipe and Tubing:E273 - 15:Standard Practice for Ultrasonic Testing of the Weld Zone of Welded Pipe and Tubing:E317 - 16:Standard Practice for Evaluating Performance Characteristics of Ultrasonic Pulse-Echo Testing Instruments and Systems without the Use of Electronic Measurement Instruments Radiographic and Ultrasonic Testing of WeldsThis testing method is usually suited to having access to both sides of the welded joint (with the exception of double wall signal image techniques used on some pipe work). Although this is a slow and expensive method of nondestructive testing, it is a positive method for detecting porosity, inclusions, cracks, and voids in the interior of welds. Seamless Steel Pipe Ultrasonic Testing MethodUpdate:2016-08-17 View(s):1922 Keywords :Seamless Steel Pipe Ultrasonic Testing Method Testing principle The ultrasonic probe can achieve energy conversion and ultrasonic sound energy between the physical characteristics of the propagation in elastic medium when the pipe is the basis of the principle of ultrasonic flaw detection.

MIC, pitting, wall loss, corrosion buildup, ice obstruction Specializing in Fire Sprinkler and Process Pipe Inspection. Satisfies the Assessment of Internal Condition of Piping on sprinkler systems as required every 5 years under chapter 14 of NFPA 25. The Various Methods Of Steel Pipe Quality Testing Feb 04, 2015 · However, hydrostatic testing is only the tip of the iceberg when discussing methods for inspecting steel pipe. Ultrasonic Testing. Ultrasonic tests can be run to determine the wall thickness of a pipe, which is important in determining what pressure it can contain and how much it can support as a structural component. Ultrasonic Inspections Ultrasonic Testing Northampton PAUltrasonic Testing, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz and occasionally up to 50 MHz are launched into materials to detect internal flaws or to characterize materials.For ultrasonic inspections, the technique is also commonly used to determine the thickness of the test object, for example, to monitor pipework corrosion.
The pipe shown in Fig. 1 was ultrasonically inspected and removed from service based on ultrasonic thickness measurements which indicated wall thinning to thicknesses as little as 0.096-inches (a thickness of O.096-inches was at or below the absolute minimum for this type of pipe). Once the pipe was removed from service (at Ultrasonic Testing (UT) :Principle, Advantages, DisadvantagesUltrasonic testing (UT) is a non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested.. Ultrasonic Testing. 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. Ultrasonic Testing - Applied Technical ServicesATS uses ultrasonic testing techniques that can detect common and uncommon discontinuities caused by base material processes and fabrication.
