RT of hydrogen pipeline

Hello,

I would like to undertake RT using Ir 192 of a cirseam weld of a hydrogen pipe of about 8 mm thick Carbon Steel when Hydrogen is flowing inside. The pipe is at room temperature.

Is it safe ? Any guideline available ? Anyone having prior experience ?

Thank you

Ananthan

General discussion & idea
Radiography principle differnetial absorption and scattering of radio waves to differnet material density.
Hydrogen in gas state will be more than denser than normal air, but it will not affect the RT images as water inside the pipe, Safety point Hydrogen to b discussed

Re: RT of hydrogen pipeline
It is agreed that hydrogen will have no effect on the image quality, but it is less dense than air and explosive.
Radiography should pose no safety issues. (Assuming the pipe is not leaking).

l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
