The current trend for WorkSafe WA is yes, the design must be registered, (Hazard Level A,B,C,D) The individual Item to be registered must have the "U" stamp. This is to ensure the quality control ASME specifies has been carried out.

Madie, gr2 may have given you some incorrect information. In Western Australia, the Regulatory Authority, WorkSafe, would require the repairs to be as per the Standard used for fabrication. If it is a AS1210 vessel, it must be repaired to the Standard. If it is an ASME vessel, it must be...

It's been a while since I have ut'd any welds but have never heard of doing shear wave inspections of welds through paint! The paint must always be removed at least the standoff distance for that angled probe.

plastcc, be aware that hanging from a harness is only intended to be short term duration, the tripod sysytem must be used with a 'bosuns chair'. This will allow the bloodflow to the legs to continue.

Hydrotor, AS 1210 has a supplement for higher pressures. Supplement 1, and it is for vessels of advanced design and construction.

Georgiaki, Having the vessel 'U' stamped is essential in some states, to enable design verification to happen. The next thing to consider is who in Australia has 'R' stamp to repair the vessel if necessary? Only one place that I know of. You are better off having the vessel verified to AS 1210...

AK1965 Try this.AS 1345-1995 Identification of the contents of pipes, conduits and ducts

Insideman, try Australian Miniature Boiler Safety Code. If a higher pressure is required than the code covers, try Australian Standard 1228 Boilers. Good luck TTT

Not unheard of. In remote sites it is possible to demag the local area sufficiently for welding by wrapping the welder leads around the pipe ajacent to the weld. Switch to AC, and make several welds (on scrap), each time reducing the ampage. Sometimes it works enough to stop the weld rod being...

Strange advice gr2vessels, we are currently having problems accepting ASME vessels here in Australia as they dont always comply with AS1210, and vessels that do may need a welder to come from USA to repair them, very hard to find a welder here that is qualified to weld to ASME.

Low frequency - less beam spread Higher frequency - more beam spread Bigger diameter - smaller beam spread As William explained, twin crystal probes are focussed but still have some beam spread, although this depends on depth or distance from probe. In plate, automated UT is not overly...

Contact Australian Standards at their website.They have a catalogue.

Proper usage is important, try leaving the blade up when finished, that way moisture will run away from edge, not onto it in drop form

Hi Max, i have a chart, ISO and AS K185, which depicts colour coding used in Australia.Here is my email, send query and i will send it to you. geoff_@ wn.com.au

Hi Ruby do you have existing corrosion, or corrosion under the floor?

Australian Standards would require 2 pressure safety valves, one must be spring-loaded type

PWHT is more determined by the metal group and its wall thickness than contents.The construction code/standard of the vessel should specify or refer to a code that does.

The vanadium in the casing enhances the properties of the other alloys. In particular it improves the fatigue resistance of the base metal.Your weld repair may have included the wrong consumables ie welding rods. There are very specific terms relating to PWHT of CrMoV. Can your unit be de-rated?

I watched a technician test structural steel welds 8-20mm thick with a 45deg then size defects with a 60deg probe. Would a 45deg be suitable for low wall thicknesses?

Is profile radiography the best way to test tube bundles in a heat exchanger?
