Nominal thickness would be tg (governing thickness).

For Div I,In my opinion the additional pwht when it is not required by code may settle residual stresses and enhance the grain refining thus increasing toughness and reducing the chance of brittle fracture. That's why code give us the benefit of additional 17 deg C reduction in impact temperatures.

In case of pneumatic testing additional requirement(MPI/DPT) of ASME VIII-1 should be met.

Thanks for response but here is a confusion that if same stamp is not required then why level guage is mentioned in battery limit of S stamp per PG-58.

Dear All, Please let me know if the level guage used for boiler is required to be S stamped ,Or if we buy it from somewhere else does it required required with partial stamping? Considering ASME SEC I PG-58.3 The boiler is deigned on ASME SEC I.

Dear All, I need a guidance as below; Is it possible to perform Eddy Current Testing of tubes for a water tube boiler. Please note that the boiler is in service and these tubes are furnace walls of boiler. For clarity the wall is made by joining several tubes with each other through a sealing...

What is the construction code? However for ASME codes it shall be dealt under ASME SEC V -Article 2 (see film marking).

Hi folks , Can anyone explain the details of pull out test required to check the strength of tube to tubesheet joint with expansion only. I need a brief methodology and the standard for acceptance criteria.

@ metengr as per NBIC part 3 para 3.3.2 (e) it falls under routine repair. Please correct if I am wrong.

A heat exchanger designed on ASME VIII-1 was in service. Now client want to alter some of the design parameter of channel side for e.g increase in MAWP and change of expansion bellow . Due to this change we need to manufacture new channel heads. Now the fabrication of channels will be done at...

A vessel on ASME VIII-1 with impact test requirement requires modification in internal weir plate.Modification is simply to increase the width of weir plate. Is this work be considered as a routine repair?

(a) The following rules shall apply in addition to general rules for forming given in UHA-40. (1) If the following conditions prevail, the cold formed areas of pressure‐retaining components manufactured of austenitic alloys shall be solution annealed by heating at the temperatures given in Table...

Thanks metengr, can you please tell me what is the range of temperature where we consider it hot forming? Also let me know what are the requirements after hot forming and where they are addressed?

The forming temperature is 420 deg C.please also guide for testing as recommended by material specification.i have a confusion regarding plate heat treated condition like what would be the case when plate is normalized and what would be the case when it is not normalized .

A dishend is made using hot forming. The material is SA 516 Gr 70 normalized, thickness is 30 mm and fiber elongation exceeds 5 % . Is pwht and mechanical testing required? Construction code is ASME SEC VIII-1.

Yes this is for mechanical testing.

Is through thickness test is a requirement of ASME sec II or VIII-1 for below case? We are making a tubesheet of material SA 516 Gr 70 N. Please also guide when it is recommended.

Please define what is the leak path dimension mentioned in said clause of ASME SEC IX.

45 minutes minimum for 3/4'' and 90 minutes minimum for 1.5''.Above 2'' we get an exemption by covering a thickness of 1'' in 15 minutes.15 minutes time is the lowest possible holding time w.r.t the thickness.

Evidence of compliance stands for the values of all mechanical and chemical testing.
