Hi all. This is not my area and that's why I request your help.
In a oil product pipeline what should be the restfill pressure? The restfill is done with the product that specific pipeline transports (ULP, ADO, HFO or JET). My concern is regarding some grade of corrosion prevention.
If there...
Hi. We are building a new tank farm and we are having now some problems with our Instrument Air lines testing. They were designed to be threaded and pneumatic tested. The issue is that the construction company is having problems with the criteria of zero leaks during the test (1.1 the Design...
Piping Systems testing. It's not the best practice, especially with ball and gate valves, but there is any standard that doesn't allow to pressure test against valves? ASME B31.3 345.3.4 seams to allow that. Can you please give me some points of view regarding this?
I would like to ask if there is any regulation/guideline, regarding the Identification of Storage Tanks (API 650). This in terms of size, style and format of lettering. Also regarding colour and location.
Can I find this information/guideline or it's ALL Owner definition.
Thanks.
Could you please give some advice on Figure 8 Blanks CS protective coating. Is there any requirement. Contractor says it can't be painted and we don't agree with that.
Can anyone please give me information about requirements for warning tapes for underground pipelines (oil products). Namely regarding lettering. Does it needs to have lettering or not.
Hi to everyone, I'm having a problem with an approved WPS for welding a 18" 7.92mm pipeline.
WPS have SMAW for the root and FCAW-S for the Fill and Cap. The first x-rays showed too many spatter in the bottom, that makes the film impossible to interpret. I know that this is a issue already known...
Hi to everyone, I have a question about WPQ and WPS.
We are welding a pipeline 18", 7.92mm with SMAW+FCAW-s and the respective WPS.
The contractor is using a welder qualified not for the above WPS but for another one that just covers SMAW (they call it a repair WPS) and he is just doing the...
Orifice Restriction Plates data sheets specifies that they should have a tab (handler) with some information (Tag Nr, Bore, Line ID, upstream). That's what the design specified for the project. Now the same design team is saying that the Tab is to be removed after installation. I never heard...
Normally it's usual to have 100% RX for underground piping systems containing oil products, 10% RX and 10% PT for aboveground piping systems. But what about firefighting, water and waste water piping systems? Any NDT requirement besides the normal visual inspection?
Also normally I see ITP's for...
Our contractor issue their PQR's and WPS's according to ASME IX.
They choose for some of them AWS A5.1 E7015 electrode. From what I can understand this is the first type of low hydrogen electrodes and now it was mostly replaced by E7018 that contains iron powder in the covering.
We will ask...
Hi, we were asked to replace some cold bend items for induction bend in the construction of a pipeline built in accordance with ASME B31.4.
What can you say to me about this issue? They say that will be easy for them to use induction bend instead of the cold bends.
The API 650 Twelfth Edition have some new definitions. One is regarding the inspector.
A representative of an organization who ensures compliance with this standard and is responsible for various quality
control and assurance functions as outlined in this standard
What kind of organization are...
When the API 650 talks about the Purchaser inspector, what kind of person are they talking about? A third party entity? An API Inspector?
At the end of the construction who will certify that the tank meet the requirments of API 650?
Thanks in advance for your time.
Just a simple question, which cerified quality systems are accepted in conformity assessment module D1 according to the european pressure equipment directive?
Thanks.
In section 8 of API 650 it states that the NDE personnel should meet the requirements of ASNT SNT-TC-l
A. This for RT and UT.
It's acceptable to have all the NDE technicians certified by ISO 9712 instead of ASNT SNT-TC-l
A?
We have in our project the following liquids: ULP unleaded petrol, ADO automotive diesel oil, HFO fuel oil and JET A1.
How did you classify this products under PED?
I think they are all group 1, but what do you think? And there is any easy way to do this classification.
What do you think about having a storage facility with a dedicated pipeline receiving Jet A1 or a multiproduct pipeline to Diesel and Jet A1?
I was Reading about this issue and I can find the two ways to do this, the dedicated one and the multiproduct.
In the project that I’m involved we are now in the design phase. I’m more from quality control and assurance but I want to help. We have right now an issue regarding the tie in point of our pipeline and a pipeline of other facility. The question is that the flow rate is the same and our pipe...
