Hi Jon,
I am just replying to see if you managed to obtain any information on your query regarding KOSHA ?
I represent a UK Vessel fabricator who are trying to find a way of importing our vessels into Korea.
We have spoken to several of the UK Inspection Agencies and haven't yet managed to see...
I am reviewing a material certificate for some Duplex St.Steel forged bar and one of the values states -
Ingot Reduction = 6.4.
Does Ingot Reduction relate to the Forging Ratio ?
i.e. does an Ingot Reduction of 6.4 = Forging Ratio of 1/6.4 ?
Apologies if this is a basic question.
Thanks in...
SA358 is a material grade included in ASME IIA as an ASME recognised material.
The specification is for Electron Fusion Welded Pipe with the addition of filler metal.
However in ASME VIII section UG-8 sub note 3, it states that pipe or tube welded with the addition of filler metal may not be...
Hi All,
Can anybody advise as to whether PD5500 Enquiry Case 87 is still valid regarding the use of Duplex stainless steel on PD5500 vessels ?
I have been advised by a client that it is has been withdrawn and I have also found a thread on this site stating this.
However we have a new copy of...
We have a query regarding the manufacture of elbows to SA403 which require welding with the addition of filler metal.
These elbows are to be used on a vessel u stamped as per ASME VIII Div.1
If a 24" short radius elbow is manufactured from plate and has 2 welded seams (with filler metal), SA403...
eyec,
Thanks for your response.
The problem Im having is that several sources state that Verification is 'does it work on paper' and Validation is 'Does it work in reality'.
Yet several other sources agree with yourself (i.e. the reverse)
Hi group,

Hi, we are an ASME U stamped shop located in the UK and we have received an enquiry for a U stamped vessel which must also adhere to CSA B51.
Can anyone advise me on how the inspection would work.
Do we have the fabrication and welding inspected by our ASME AI and then have the designs sent to...
SPARKYLARKS,
Thanks for the reply.
The Skid contains a chemical dosing unit consisting of Pipework and Pneumatic Pumps.
We will be CE marking these as per Pressure Equipment Directive and Lloyds are assessing the design and build accordingly.
There is no guarding required.
We often build...
micalbrch,
Thanks for the reply.
Our client has insisted on CE marked equipment.
I think its to cover the lifting at the dockside (i.e. before its on the ship).
We are building a chemical dosing unit which is to be mounted on a skid frame and is to be used offshore.
We have been asked to supply a CE declaration of conformity to cover the lifting assembly.
In the past this would just include the lifting beam and shacles etc.
However our client has stated...

We are designing a ‘stacked’ pair of horizontal vessels whereby one vessel sits on top of another.
The vessels will have saddle type supports and the supports for the upper vessel will be in-line with the lower vessel supports.
The lower vessel will therefore have wrapper plates welded on the...
Sudduth,
This works if you ant all characters the same but I want a different value at each orientation.
I think the method Beachcomber suggested is the best way.
Thanks everyone
