Description

초음파 고온 튜브 검사 장치 {Ultrasonic Highi-Temp Tube Inspection and Thickness Measuring Apparatus}Ultrasonic Highi-Temp Tube Inspection and Thickness Measuring Apparatus}

본 발명은 초음파 고온 튜브 검사 및 두께 측정 장치에 관한 것이다.The present invention relates to an ultrasonic high temperature tube inspection and thickness measuring device.

본 발명은 초음파 고온 튜브 검사 및 두께 측정 장치에 관한 것으로서, 보다 상세하게는, 고온 튜브나 파이프라인에서 발생하게 되는 부식이나 마모와 같은 재료의 감소 즉 두께 감소 등의 상태를 초음파를 이용하여 측정함으로써, 이상(異常) 상태를 초기에 정확하게 검사/측정하거나, 부식이나 마모 경향을 관리하기 위한 측정 장치에 관한 것이다. 본 발명의 초음파 고온 튜브 검사 및 두께 측정 장치는 한 개의 초음파 탐촉자로 송수신을 하게 되며 한 개의 초음파 펄스 장치로 분배기를 사용하여 여러 초음파 탐촉자로부터의 신호를 순차적으로 처리할 수 있다. 본 발명은 튜브나 파이프가 손상되거나 측정 장치를 설치하기 위해 작업 과정을 중단하지 않고 설치할 수 있는 특징을 가지고 있다.The present invention relates to an ultrasonic high temperature tube inspection and thickness measuring apparatus, and more particularly, by measuring the state of the reduction of the material such as corrosion or abrasion occurring in the high temperature tube or pipeline by reducing the thickness by using ultrasonic waves. The present invention relates to a measuring device for accurately inspecting / measuring abnormal conditions at an early stage or managing corrosion or wear tendency. The ultrasonic high temperature tube inspection and thickness measuring apparatus of the present invention transmits and receives with one ultrasonic probe, and can process signals from several ultrasonic probes sequentially using a distributor with one ultrasonic pulse device. The present invention has the feature that the tube or pipe can be installed without interrupting the work process in order to damage or install the measuring device.

일반적으로, 초음파를 사용하여 금속이나 플라스틱의 재료를 검사하거나 두 께를 측정하고 있으며 재료가 고온인 경우는 특별한 초음파 탐촉자를 사용하거나 카플런트를 사용하여 순간적으로 측정을 하였다. 반면에 정유, 발전소 등에서 사용되는 고온 튜브나 파이프라인의 경우는 일반적으로 보온재에 덮여 있어서 접근이 용이하지 않을 뿐 아니라 내용물이 계속 흐르고 있어 측정 장치를 설치하는데도 많은 제약이 따르게 된다. 또한, 초음파 탐촉자를 고온에서도 견딜 수 있도록 제작하게 되더라도 오랜 시간을 버티는 것이 거의 불가능하며 수신 감도도 상당히 떨어지게 된다. In general, ultrasonics are used to inspect metal or plastic materials or to measure the thickness. When the material is hot, a special ultrasonic probe or a capplet is used to measure the thickness. On the other hand, high temperature tubes or pipelines used in oil refineries, power plants, etc. are generally covered with insulation, which is not easy to access, and the contents continue to flow, which places many restrictions on the installation of measuring devices. In addition, even if the ultrasonic transducer is made to withstand high temperatures, it is almost impossible to withstand a long time and the reception sensitivity is also considerably reduced.

따라서, 본 발명은 고온 튜브나 파이프를 초음파로 검사하거나 두께를 효율적으로 측정하여 설비의 상태를 계속적으로 모니터링하므로 불량 튜브로 인한 폭발 사고를 방지함은 물론 설비의 상태를 관리/예측하여 교체시기를 결정할 수 있도록 한다. Therefore, the present invention continuously monitors the condition of the facility by inspecting the high temperature tube or pipe with ultrasonic waves or by measuring the thickness efficiently, thereby preventing the explosion accident caused by the defective tube as well as managing / predicting the condition of the facility to change the replacement time. Make a decision.

고온 튜브나 파이프를 검사하고 두께를 모니터링하고 관리하는 데는 일반적으로 초음파 측정기에 고온용 초음파 탐촉자를 연결하여 사용하게 된다. 이 경우는 측정할 때마다 보온재를 해체하였다가 다시 설치해야 함은 물론 측정값의 정밀도가 떨어지게 되고 고온에 의하여 카플런트가 증발함에 따라 수초 이내에 측정을 마쳐야 한다. 연속적인 모니터링을 하기 위해서는 전기 저항법을 사용하고 있기는 하나 수치 해석에 많은 시간이 걸리며 측정용 스틱을 설치하기 위해서는 금속 스틱을 튜나 파이프에 용접을 해야 한다. 그밖의 전자기 초음파를 이용한 두께 측정 방법이 있으나 일정 온도를 넘게 되면 탐촉자 안에 들어 있는 영구 자석이 자기력을 잃게 되어 신호를 읽을 수 없으며 영구 자석 대신 전자석을 사용하면 부피가 너무 커져 서 실용성이 없어지게 된다. 그 외에 고온에서 검사/측정하기 위한 여러 가지 구조의 탐촉자들이 나와 있기는 하나 근본적으로 액상의 카플런트를 사용하므로 장시간 측정을 하는 것이 불가능하다.In order to inspect high temperature tubes or pipes, and to monitor and manage the thickness, a high temperature ultrasonic probe is usually connected to an ultrasonic meter. In this case, the insulation must be dismantled and re-installed every time the measurement is made, as well as the accuracy of the measured value is lowered and the measurement must be completed within a few seconds as the kaplan is evaporated by high temperature. Although the electrical resistance method is used for continuous monitoring, it takes a lot of time to solve the numerical analysis. To install the measuring stick, the metal stick has to be welded to the tube or pipe. There is another method of measuring thickness using electromagnetic ultrasonic waves, but if the temperature exceeds a certain temperature, the permanent magnet in the transducer loses its magnetic force and cannot read the signal. Other probes are available for inspection / measurement at high temperatures, but the use of liquid capplets is fundamentally impossible to make long-term measurements.

그러므로 본 발명의 초음파 고온 튜브 검사 및 두께 측정 장치는 초음파를 이용하여 고온 상태에서 튜브나 파이프를 검사하거나 두께를 측정하는데 있어 고온 상태를 일시 중단시키거나 튜브나 파이프를 손상시키지 않는 상태에서 초음파 탐촉자를 설치하고 웨이브 가이드(wave guide)를 통해 송수신하는 초음파 신호를 장기간 모니터링하는데 목적을 두고 있다. Therefore, the ultrasonic high temperature tube inspection and thickness measuring device of the present invention uses ultrasonic waves to inspect the tube or pipe at high temperature or measure the thickness without suspending the high temperature state or damaging the tube or pipe. It is aimed at long-term monitoring of ultrasonic signals transmitted and received through wave guides.

결과적으로, 본 발명에 따른 초음파 검사 및 두께 측정 장치를 사용함으로 고온 튜브나 파이프에서 고온 상태를 일시 중단시키거나 튜브나 파이프를 손상시키지 않는 상태에서 초음파 탐촉자를 설치하고 연속적으로 혹은 주기적으로 두께 데이터를 수집하여 사고를 방지하거나 설비의 상태를 효율적으로 관리할 수 있는 효과를 가질 수 있다. 또한 여러 개의 초음파 탐촉자를 경사각으로 배치할 경우 장거리 초음파 검사가 가능하다. As a result, by using the ultrasonic inspection and thickness measuring device according to the present invention, the ultrasonic transducer is installed without suspending the high temperature state in the hot tube or pipe or damaging the tube or pipe, and continuously or periodically collecting the thickness data. Collecting can have the effect of preventing accidents or efficiently managing the condition of the facility. In addition, when ultrasonic transducers are placed at an oblique angle, long range ultrasonic examination is possible.

이상에서 본 발명에 따른 바람직한 실시예에 대해 설명하였으나, 본 기술 분야의 당업자라면 첨부된 특허청구범위를 벗어남이 없이 다양한 변형예 및 수정예를 실시할 수 있을 것으로 이해된다. While a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.

이하, 본 발명에 따른 바람직한 실시예를 첨부 도면을 참조하면서 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It is achieved by a metal captive (3), a cooling chamber (4) through which coolant is circulated, and a metal strip that compresses / fixes the entire ultrasonic transducer to a tube or pipe.

This signal passes through the waveguide 2 and passes through the metal captive 3, reaches the bottom of the tube 8, is reflected, and then passes through the metal captive 3, and then passes through the wave guide 2. It is received by the ultrasonic vibrator 1 through. This signal is amplified by the ultrasonic pulser / receiver again and converted into a thickness value by the microcomputer of the circuit part, and the PC system manages the entire data.

결과적으로, 본 발명에 따른 초음파 검사 및 두께 측정 장치를 사용함으로 고온 튜브나 파이프에서 고온 상태를 일시 중단시키거나 튜브나 파이프를 손상시키지 않는 상태에서 초음파 탐촉자를 설치하고 연속적으로 혹은 주기적으로 두께 데이터를 수집하여 사고를 방지하거나 설비의 상태를 효율적으로 관리할 수 있는 효과를 가질 수 있다. 또한, 여러 개의 초음파 탐촉자를 경사각으로 배치할 경우 장거리 초음파 검사가 가능하다. As a result, by using the ultrasonic inspection and thickness measuring device according to the present invention, the ultrasonic transducer is installed without suspending the high temperature state in the hot tube or pipe or damaging the tube or pipe, and continuously or periodically collecting the thickness data. Collecting can have the effect of preventing accidents or efficiently managing the condition of the facility. In addition, when a plurality of ultrasonic transducers are arranged at an inclination angle, long range ultrasonic inspection is possible.
