But, The skirt has 42mm baseplate and compression ring welded to skirt with 14mm throat fillet weld.Do you think this sirt part need PWHT?

Thank you all.I think skirt does not need PWHT under these conditions.

Metengr, Skirt has 3 parts and bottom head is welded with top skirt part which is already the same material with Shell=SS304(20mmthk).Then second and the third parts of skirt are SA51670 with 20 and 30mm subsequently. Other than filler material I need to know for this CS bottom part of skirt not...

Hi, We have a vertical pressure vessel with skirt.Vessel material is SS304 but skirt is SA51670 with 20 and 30mm thk. subsequently.Shell&heads do not need heat treatment but should I heat treat the skirt material? I'm looking at UCS-56 yes it needs but this part is nonpressure part? Can anyone...

Thanks Metengr. Materials will have EN10204(2004ed.) 3.1 certificates. Acc to your reply it must not be ASME material.Am I misunderstanding?

Friends, I'm designing a D-Type Water tube boiler Acc. to ASME sect I ,Ed.2004. For lifting lugs,external attachments etc. I want to use St37-2 DIN material. Our AI say material must be ASME material.But St37-2 is not ASME material and since these parts are non pressure parts(please someone can...

Bimr. Piping size will be 21/2" and demi water will be about 77°F.(min.32°F)do you think thermal expansion important?

Thanks Bimr. Demi water will be used for a boiler system.So,impurities are not as important as UPW.

Could anyone help me on plastic piping materials,can be used with demineralised water? Can I use just PVC pipes for outside transportation?

Kryanl. As far as I understood, even the tank open to the atmosphere, while draining the tank, if any procoution did not taken against vacuum or if the vent pipe to atmosphere is not designed to meet all possible vacuum requirements, as a protection, tanks designed to withstand some vacuum.This...

Jaypack. I think before choosing material you should know the exhausht gas temperature and content of exhaust gas.Then you can choose materials.If acid formation occurs with SA285GrC the same thing occur with the SA516Gr70.If So2 content of flue gas is quite high, maybe you should try SA240...

I started the design of single flue shell boiler will produce 20000kg/h steam@10barg.For the design of furnace I have to calculate the thermal stresses resulting from such big loading into one flue.I'll use P295GH material.The furnace will be deep corrugated type.Without applying FEA which way...
