WARTSILA AB FINLAND

Hello, for a ship gas pressure vessel reparation, we are very interesting if any one known a equivalent steel specified originally as:
RAEX 34 SLT
It seems that this specification is related with FINLAND standards.
These pressure vessels was bult by WARTSILA AB FINLAND.

This pressure vessel was built on 1985 and the design was made in 1982 or 1983.

Thanks in advance

You are correct in this being a Finnish steel. Produced by Rautaruukki (now Ruukki) http://www.ruukki.com/www/corporate.nsf?OpenDatabase&lang=1 RAEX is still one of their trade names. I am not sure about the exact designation you gave but 34S was classed as NV4-4 (low temperature carbon pressure vessel steel). I suggest you contact them via their home page to verify the other letters.

the scanning area and the system settings should be flexibly adapted to the test task and the material. These high expectations are met with the new and modular testing system SONOAIR. With the world’s first air-coupled phased-array UT inspection system SONOAIR we developed a technology that works with up to 4 transmitter and receiver channels with freely configurable square wave burst transmitters as wells as low noise receiving amplifiers.

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.
