Hi, 135 should refer to "gas metal arc welding using active gas" and 141 should refer to "gas tungsten arc welding using inert gas". Numbers are coming from standard EN ISO 4063:2009. Here's a link to the web site from where they can be found also...

You can start from here: http://www.cbpvi.org/ There's a lot of information including regulations, procedures, guidelines... Hartsa

Uups, boilerone was quicker than me... Hartsa

Hi, It is wrote in the procedures of manufacturing licensing: "The Manufacture License is valid within four years beginning from the date of issuance. The license holder should apply for license renewal in writing to the Safety Supervision Department directly under AQSIQ or Provincial Quality...

Hi, I'm writing from Finland. You might know us from the Flyers, where Ville Leino is kicking some Hawks butt right now ;) But back to topic. Chamber of Commerce was a good call. I contacted one Finish representative working in China and he promised to look into it. I think it's going to work...

Thanks Boilerone! I found also that $440 version and thought that holy s...! And I downloaded the "for approval" version earlier, but there seems to be some differences in categorisation diagrams on annexes A between 'for approval' and '2009' version. Have you noticed? So I dont know can this...

Hi! Dont know if this is the right forum to ask but here goes. China has revised some of regulations regarding pressure vessels last year. New regulation of stationary pressure vessels is called TSG R0004-2009. I have been trying to find TSG translated to English but with no luck. Does anyone...

Hi, Calculation sequence is presented after table 2 in the standard EN1591-1. When calculating for example ?max, calculate ?max with the equation 82 using js=+1, km=+1 and ks=+1. ?min is calculated with js=-1, km=-1 and ks=+1 and so on. Then you have to determine the value of jm (equation 80)...

Hi, I too spent quite a long time few years back in producing excel calcs according to EN13445-3 annex G. Nowadays there are commercial softwares such as VVD that does these calculations. But calculating FG? according to EN1591-1 (equation 51) means that you have to calculate FG? in every...

We are using VVD and it can calculate flanges according to EN1591 or EN13445-3 annex G. It also calculates flanges according to EN13445-3 clause 11 (Taylor-Forge Method). So you can calc non standard flanges with VVD. But I think that it does the same as your MathCad. You give some thickness to...

gr2vessels, Your absolutely right, I am trying to calculate thickness of bolted flat end according to AS1210. But there are some sentences in the code that I cannot understand. For example, in 3.18.12.2 "at least equal to 50 percent of the total required for these two openings". What is total...

Thanks for replies. doct9960, It seems like that AS1210 doesn't have similar factor h as in ASME. But did you ment that unpierced thickness (26,93mm) should be multiplied with factor h? gr2vessels, I didn't quite understood your advice. Can you be more specific, so that rookie like me...

Hi all, I am trying to figure out thickness of bolted flat end according to Australian AS1210. You can see the plate and openings attached. I calculated the minimum thickness with equation 3.15.3(2) in AS1210 and got the result of t=26.93mm. Next I calculated required increased thickness with...

Thanks for your reply gr2vessels. Last friday I received information regarding one of our older project. I was told that earlier our vessels were designed and fabricated according to EN 13445 (standard, that is harmonized with European pressure equipment directive) and then they were inspected...

Thanks for your replies. This "problem" started yesterday when our project manager came to me and asked if I could look into this. Of course I wondered that why he didn't asked this question from our client. but I thought that I try to find out this one myself anyway. Now it's clear to me that...
