OK Asme section IX gives P number 4 for CrNi545 material-table QW/QB-422. What about the temperature and time of heating from where do we get it?

Hay what is the PWHT regime for 13CrNi4-5 material as per ASME? Thanks

Hay ! Does there exist a standard which defines the maximal allowable working pressures of the valve actuators? Does somebody know some test which can be performed for this? Can this be calculated? What about maximaldamage pressure for the actuiator-by this I mean the pressure which can be...

Hello to all! Let say that we have all available parameters for SIL of valve (Lambda valve, PFD valve), actuator(Lambda actuator, PFD actuator), solenoid valve (lambda sov, pfd sov)and booster (lambda b, pfd b). Can you tell me how do you estimate SIL parameters from individual parameters for...

Hay there! has somebody some experinces with phosphate conversion coating for the cast valve bodies used for valve applied in oxygen process. To use it as corrosion preservation. Some info if according to wha, aiga, and so on. any input is welcim! Thanks

Hyy! I didi mistake in writing I thought a layer which appear on the metal surface after it is heated and when metall atoms react with oxygen. mayebe a Mill scale. After the surface will be treated with HCl we will clean it neutralise it as according to EIGA requirements.

Hay! I have a A351 CF8M cast steel which is full of tunder in the corners. I am aware that Hcl is not an appropriate acid but it removes the tinder away easier and mor eeffective as grinding which is not possible due to place problem (corners). If I apply HCl with a brush for 5 Minutes and...

Hay! Costumer requires a controlvalve which can survive winterisation of a ship after Lloyd register . I inspected register and there are several winterisation classes a,b,...etc Does sombody have some experiences with this subject? What should we take care on? We have experiences with...

Hay all! We are searching a valve seat leak station which is safe, that is secured by walls like a bunker for clean room where ultra high pure valve are produced and tested. Does somebody have some information about a supplaier of such stations or did you do it by yourself? thanks for answers...

Hay, does there exist a list of materials which are appropriate for usage at bolts and nuts at valves according to NACE standard? If yes where can I get it? I would liketo thank you for the send answer! Trentar

Hay ist there some special standard which describes seat leakage measurement for three way valve or should I use standard for two way valve like -ASME B16.34, -ANSI FCI 70-2, -EN 1349, -EN 12266-1, -IEC 60534-4? Thanks

Supplier is akzo nobel - Intertherm lack is used as a cover. As crosslinker - a hardener or some other stuff which would improve the stabiliaty of a paint system outdoor.

Hay! Our metal surfaces (from Al, SS, CS) are after few years completely without colour. We are located in a desert and metal surfacea are all the time located outside of buildings. We prepare metal surfcae according to paint supplier request.In few years the metal surfaces look like that they...

Hay there! Does there exist a standard which provid eus allowable seal tolerance - how much is allowed? i am interested in packing seal for valves. Thank you

hay there! Does there exist a list of materials for valve body material which should be used for various fluids which flow through the valve for various process conditions (like pressure class, flow etc.)- If yes where can I found this list! thank you t

Hay! I posted this on some other part of forum but did not get answer. maybe here fits more? Does somebody knows standard which measures electrostatic charge of valve in dynamic state -> between valve openning and clossing btw. valve is working state. I would need this for ATEX,... I have only...

Hay! Does somebody knows standard which measures electrostatic charge of valve in dynamic state -> between valve openning and clossing btw. valve is working state. I would need this for ATEX,... I have only found standard for measureing electrostatic charge of valve in static condition EN ISO...

Hay, it will be difficult to find data. what I do, I found material with similar properrties to 1.4122 and select such a steel which has an asme equivalent and after just read the data from standard,...there is a lot of different steel nowdays. unless your costumer really want 1.4122 you can...

specify process conditions in reactor vessel. is it liquid process? any gas? take care on material surface corrosion chemical compatibility in reactor process pressure process temperature friction between fluid in reactor and chemicals in it process cycles (how many times you plan to heat up...
