Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated the detection method for sample tube that has oblique wound of the present invention.
Method of the present invention be with having of an Apparently in Good Order﹠ Condition artificial steel pipe of tiltedly hindering be the artificial of angle of inclination with the steel pipe bus and tiltedly hinder 2 as detecting 1 (as shown in Figure 1) of sample pipe, on body, having, artificial angle of inclination of tiltedly hindering is measured.The measuring method of tiltedly hindering the angle of inclination of this detection sample pipe, at first solved the definite problem of tiltedly hindering the angle of inclination that detects the sample pipe, prove by analysis, the final bus of determining to detect the sample tube-surface 2. with the angle of the oblique wound that detects the sample pipe 3. (as shown in Figure 4), the oblique wound that is detection sample pipe is to detecting the angle of inclination of sample pipe, thereby obtain this bus that detects the sample tube-surface 2. with the sample M of the angle of the oblique wound 2 that detects the sample pipe, that just can measure detection sample pipe tiltedly hinders the angle of inclination.Secondly, be the bus of acquisition science, desirable detection sample tube-surface and the sample that detects the angle that the sample pipe tiltedly hinders, need to guarantee to detect the bus accurate positioning of sample tube-surface, made for this reason and met theoretical subtest instrument triangular form chi S (as shown in Figure 2), make it directly obtain to detect the bus of sample pipe and the angle of tiltedly hindering the pitch angle at work, thereby provide reliable technique to guarantee for the obtaining of angle of inclination sample of tiltedly hindering of detecting the sample pipe.Simultaneously, to detecting the detection of tiltedly hindering the angle of inclination of sample pipe, adopt the endoscope of band numeral differentiation plate, directly obtain angle value at small space.
The detection method for sample tube that has oblique wound of the present invention, its method comprise following detection step:
At first, detect the analysis that the sample pipe is tiltedly hindered the position, inclination angle
Shown in Fig. 1,4, because steel tube surface is the camber structure, measures and detect artificial tiltedly wound of sample pipe and the angle of inclination of detecting the sample pipe, at first must find reference point.3. artificial tiltedly the wound and the angle of inclination of detecting the sample pipe be exactly manually tiltedly hinder and detect sample tube's axis angle (as shown in Figure 4) 1..And artificial tiltedly wound objectively is disjoint with detecting the sample tube's axis, and real artificial tiltedly wound is on the surface of detecting the sample pipe.According to the geometric configuration that detects the sample pipe, 2. the bus that detects the sample pipe is parallel with the axis that detects the sample pipe, according to translation principle, can infer the artificial angle of inclination of tiltedly hindering and detect the sample pipe of detection sample pipe, exactly detect the artificial angle of tiltedly hindering and detect sample pipe bus of sample pipe.Therefore, as long as determined to detect the bus of sample pipe, just can measure and detect artificial tiltedly wound of sample pipe and the angle of inclination of detecting the sample pipe.
Then, determine to detect the bus position of sample pipe
As shown in Figure 2, determine that the bus of detection sample pipe can be finished by triangular form chi S, as shown in Figure 2.Two base D of this triangular form chi require parallel.Parallel lines are rock-steady structures, when two parallel bases of triangular form chi fully contact with detection sample tube-surface, this moment, two parallel base D of triangular form chi were 1. parallel with the axis that detects the sample pipe, 2. overlap with the bus that detects the sample pipe, so, just the outline line on two parallel bases of triangular form chi can be thought to detect the bus of sample pipe, thereby determine to detect the bus of sample pipe.
Then, detecting the sample pipe tiltedly hinders angle model and obtains
As shown in Figure 3, in practical operation, with two base D of triangular form chi with detect that the sample pipe is stable contact, the base that makes the triangular form chi with detect the sample tube-surface and tiltedly hinder crossing, adopt the method for applying film, tiltedly hinder the intersection on the base of triangular form chi with detection sample tube-surface and make angle model M.Utilize the optical projection instrument that the angle model that is obtained is measured then, thereby obtain to detect the artificial tiltedly wound of sample pipe detecting the angle of inclination value of sample pipe.
Mobil Oil Corp.'s product certification adopts international up-to-date technical standard, and wherein most important is exactly to detecting 12 ° of measurements of tiltedly hindering angle of sample pipe.For realizing this important technology index, the oblique wound formation that detects the sample pipe has been carried out detail analysis.Think that the oblique wound of any detection sample pipe is distributed in the surface of detecting the sample pipe, itself and the angle of inclination of detecting the sample pipe are disjoint in the space, and its angle is relative, and this just brings difficulty for its measurement.The parallel relation of the axis of analyzing and testing sample pipe and the bus that detects the sample pipe for this reason, the bus that can determine to detect the sample pipe with detect the sample pipe and tiltedly hinder the angle that intersects and be and detect the sample pipe and tiltedly hinder detecting the angle of inclination of sample pipe.Importantly detect the oblique injury of sample pipe and detect determining of sample pipe bus in measuring process, design triangular form chi structure, these chi two bases are parallel for this reason.In measuring process, keep triangular form chi two bases fully to contact with detecting the sample tube-surface, intersect with oblique wound of detection sample pipe on a base, at this intersection area overlay film, obtains triangular form chi base and the oblique sample pattern that intersects angle of hindering of detection sample pipe.Finally on optical detection apparatus, record this angle value.Its measuring accuracy meets the requirement of international up-to-date nondestructive testing technique standard, and access authentication mechanism is affirmed.
