Btw, yes, TAT is applicable for Check Valves as well.
BFE Italy has the approval. Apart from 77/300 test which is performed one time and valid for a certain period of time, they do 77/312 Fugitive Emission Test for the forged valves.
Thanks Ehtisham
For one of the ADCO projects that we executed, we had lot of trouble identifying and sourcing SHELL TAT approved valve vendors who can give a reasonable delivery.
For future projects, I will definitely offer our clients the 4 point alternative you mentioned instead of TAT...

Hi hsdcn . Thanks for replying.
I meant the valves which were in stock in BFE. Not manufactured specially for any project.
The valve is a piston type, reduced bore, socket weld check valve , A182 F316L body , piston disc stellited. Tested as per API 598.
I need to confirm to my client if these...
I am using Stock Check valves of size : 3/4" Socket Weld 800# of make BFE SpA, Italy.
The client has specified that valves shall be suitable for full vaccume condition. Can someone explain what does this mean.
I have checked the catalogue of BFE. It says " BFE valves can be used with standard...
Thanks DenisSBM.
I did contact HAWA valves. They have the TAT/TAMAP certificates for Ball valves only.
But do let me know manufactures of Check,Globe and Gate..
Thanks Pumpsonly.
The client wanted to use a transfer pump (for transferring Stadis from one tank to Jet Fuel in another tank).
They also wanted minimal flowrate so that the transfer does not happen quickly (0.25 LPH) and also that this pump should be API 676 compliant.
We gave a Viking Pump...
I read lot of literature about the difference and comparison between Foundation Feildbus and HART protocol.
Being a Mechanical Engineer, what is understand is that HART gives 4-20mA output signal. It is analog.
Where as FF is digital signal that can be interfaced with a DCS.
Hope i am not too...
Thanks Cloa and Katmar.
Cloa - can you please elaborate "propensity to sensitive stainless steel".
The medium in the pipelines is Jet Fuel. My line size is 2", And the pipes used are 2" SS316L , Sch 40 with mating Flanges 2" 150# RF F316L, B16.5
The chemical compatibility of Stainless Steel -...
I there a minimum flow rate required for a pump to be API 676 compliant.
We are using a transfer pump of flowrate 0.25 LPH of make Wilden, USA.
This pump will be used to transfer Stadis to a tank containing Jet Fuel.
The pump manufacturer has said that this pump follows the guidelines of API...
I understand that the difference between SS316 and SS316L is the amount of carbon content in the material. It is in less percentage in 316L than in 316. And CF3M and SS316L are the same except the latter is forged and the former is cast body.
This difference, is it only valid when there is...
Thanks for the replies.
I did contact Shell directly. It seems valve companies need to invite Shell to do their recommended testing after which they certify them with Type Acceptance Test (TAT) certificate MESC SPEC 77/300. This certificate is valid only for a couple of years and the entire...
Does anyone have a list of valve manufacturers who have the Shell TAT/TAMAP approval? I am looking for Ball Valves, Check Valves and Globe Valves of DN 25 to DN 80 .
