[MW:2113] Re: 2106] RE: 2059] Steeloscopy Test

Further, use of Arc/Spark (Spectrometer) equipment or X-Ray Fluorescence (XRF) PMI equipment depends on both the list of chemical elements required and the application such as for mobile or portable use. Spectrometers normally will be able to analyze most of the elements including C, Si, P and S (low atomic elements) but these equipments are bulky, weighs not les than 25kgs, needs Argon gas and also this requires well trained and experienced operator. On the other hand XRF instruments are highly portable, normally hand held, suitable for alloying elements such as Cr,Ni, Mo (high atomic elements), doesn't require skilled operators. Normally PMI tests are required are, only Alloy steel such as SS, Nickel base and Cr-Mo steel, hence XRF would be sufficient. Hope this help.

A brief search of the internet shows steeloscopy is Russian terminology for an arc/spark emission spectral analysis for chemical determination - thus a requirement for steeloscopy a steeloscopy test is a a requirement for PMI (chemical analysis) using the arc/spark technique/equipment.  There are a number of portable instruments available - depending on application you might propose using portable X-ray flourescence (XRF).  Arc/spark emmission spectral analysis can be much more accurate and can test for low atomic wieght elements not routinely "seen" by XRF.

As per Russian norms, Steeloscopy Test is to be performed for pressure vessels. I request members to guide me about what this test is?

 

Thank you,
