Internal Rotary Inspection System (IRIS) 內旋轉超聲檢測系統

小編:與龍共舞

IRIS is an ultrasonic method used for the non-destructive testing of pipes and tubes.

內旋轉超聲檢測系統是一種用于管道和管材無損檢測的超聲波檢測方法。

Many plant operators in the oil, gas and power generation industries are faced with the challenges of maximising the efficiency and life expectancy of their assets but without sacrificing safety and reliability. Therefore accurate inspection of vital components such as pipes and tubes is crucial to ensuring the integrity of the plant. IRIS detection technology can solve this problem.

許多石油石化、天然氣和發電行業等企業都面臨這一個問題,如何在不犧牲安全性和可靠性的情況下最大限度地提高其設備的使用效率和壽命。因此,準時準確的了解管道和管道等重要部件的實時狀況,對于確保工廠設備的完整性至關重要。

Internal Rotary Inspection System (IRIS) can detect corrosion, pitting and wall loss and is most commonly used for tube inspection in boilers, heat exchangers, air coolers and feed water heaters. It is particularly versatile as it is suitable for both ferrous and non-ferrous materials, and IRIS can be used on a wide range of tube diameters and wall thicknesses.

內部旋轉檢測系統 (IRIS) 可以檢測腐蝕、點蝕和壁厚損失,最常用于鍋爐、熱交換器、空氣冷卻器和管式反應器等的管束檢測。該技術通用性強,它幾乎適用于各種材質金屬材料,而且適用管徑和壁厚范圍也很廣。

An IRIS probe is inserted into a tube flooded with water. The probe is fitted with a transducer that generates an ultrasonic pulse along a path parallel to the axis of the tube. A rotating mirror directs the ultrasonic pulse into the tube wall. The mirror is driven by a small turbine that is rotated by the pressure of water pumped into the tube.

將IRIS探頭插入充滿水的管中,探頭配有一個換能器,該換能器沿平行于管子軸向方向產生超聲波脈沖。45°旋轉反射鏡將超聲波脈沖反射到管壁中,反射鏡子由一個小型水渦輪機驅動,該水渦輪機通過泵入探頭中的水的壓力旋轉。

The ultrasound pulses are reflected by the inner-diameter (ID) wall and outer-diameter (OD) wall of the tube and the time of flight difference between the two diameters is used to calculate the wall’s thickness.

超聲波脈沖被管的內壁(ID)和外壁(OD)反射接收,計算內外徑之間的時間可得出管厚度。

As the IRIS probe is pulled, the spinning motion of the mirror results in a helical scan path ensuring full coverage of the tube.

反射鏡持續轉動,當IRIS探頭被拉動時,反射鏡子的旋轉運動會產生螺旋掃描路徑,確保管子的檢測完全覆蓋。
