Hello All,
We we going to do some external pressure tests on a thermowell on the flange rating, but the inspector insists of an internal pneumatic test + soap detection.
We were going to put 30 barg nitrogen in the thermowell, as this is easily read on our installed manometers.
The inspector...
Has anyone seen one of these before, or are do you think they are made to order? I have been looking over several DIN and ASME standards, but do not find them.
Thanks!
Hi all,
we have some ACM cut off machines running in our shop (https://www.engnetglobal.com/c/f.aspx/ACM013). The company stopped a while ago and we had a steady supply for cutoff wheels (resinoid type abrasive). The cut off wheels measured: 4'' with a hole of 0.5'' and a thickness of 0.002''...
Hello,
we buy blind flanges according to B16.5, EN1092-1, etc. We make thermowells out of these flanges, and e.g. with 2500lbs full penetrant welded flanges, we get quite some distortion in the bolt holes.
For larger orders, we subcontract thermowells and we have one supplier that offers...
Dear,
Does anyone have experience with G-X45NiCrNbTi35-25 or maunarite xm?
I have found reformer tubes made out of G-X45NiCrNbTi35-25. I am curious to weld small (20x20x2mm) pads of Thermocouples (SS310, P8) on top of this pipe (FW).
Is there a trick to find a P number for this material? As I am...
I am trying to determine whether a +/- 40m long pipe on the floor (3'' SCH80 SS316) can be lifted vertically by a crane. The crane can only lift the pipe from one end. Will the pope knuckle? I am trying to find whether there are guidelines or empirical formulas describing this max bending...
Hello!
-a welder in our workshop showed me that his 2'' sch160 pipe had the markings SS347/SS347H on it.
Looking at the material certificate and the corresponding standards(ASTM A312-A376), chem composition can work for either SS347 and SS47H.
What is confusing is what the standard A312...
Hello XL83NL!
Please refer where you found your info.
I read in the question that the vessel was going to have a PS of 0,5 bar and like you said no demarcation lines; it is not above 0,5 bar; PED does not apply.
Or am I confused now? Also if you CE mark, you need conformity certificates and...
PED 2014 says:
As your pressure is equal to 0.5 bar, you fall under article 4, Paragraph 3 (sound engineering practice, SEP). and Article 4 paragraph 3 explicitly prohibits CE marking of SEP pressure equipment.
special circumstances could be if your vessel is part of a pressure assembly and...
