Shell DEP Pressure vessel spec

Shell DEP Pressure vessel spec

Shell DEP Pressure vessel spec

(OP)
Dear call can some one help me to know that as per Shell standard DEP 31.22.00.31 , when the specification says that all forgings shall be UT tested, does it include all standard Pipe fittings like flanges manufactured as per ASME B16.5 or does it mean to non standard forgings such as forged nozzle. Because the flanges available in market in accordance to ASME B16.5 is not UT tested and not required by specification. Thanks for your support

RE: Shell DEP Pressure vessel spec

Ultimately, Id ask Shell, however;

Quote:

A forging says something about the material, which usually means it's a flange. Whether or not something is forging is addressed by the applicable ASTM spec (e.g. A105, A182), from which your material journey 'starts'. A fitting is not a forging, and a flange is not a fitting. A flange is a flange, usually made from a forging, but sometimes from plate. You seem to have mixed up definitions here. Fittings may e.g. be acc A234 or A403.

Thanks XL83NL. Yeah im definitely wrong when i say that statement. Actually the shell standard refers to ASME SEC VIII DIV 2 supplementary requirement of Material part for UT Examination on forgings. From my understanding of part 3.2.8.2 of ASNE SEC VIII DIV 2 "Standard pressure parts such as pipe fittings, flanges, nozzles, welding necks, welding caps, manhole
frames, and covers that are wholly formed by casting, forging, rolling, or die forming shall not require
inspection, material certification in accordance with paragraph 3.2.6 or Partial Data Reports"
. So I understand that for standard pressure part such as flanges the supplementary examination of UT is not applicable for forging. Can someone correct me if i am wrong.

RE: Shell DEP Pressure vessel spec

If spec. say UT for all forgings then this include standards parts and no standards parts.

Regards

RE: Shell DEP Pressure vessel spec

Shell DEP specifies any forging 50mm and greater in nominal thickness for Cat1/2 equipment shall be UT tested.

If your fittings exceed 50mm in nominal thickness and made of forged material, then UT should be applicable.
If your blind exceeds 50mm and made of plate, Shell DEP still requires plates 50mm and greater to be UT tested.

White Paper - Guide to Integrate Large-Format Additive
As with any new technology, getting into large-format 3D printing begins with investigation. The first question may be a simple one: what does “large-format” mean? For 3D printers, “large” is a relative term. Many extrusion-based (FFF) 3D printers are referred to as desktop machines, because they fit on table space. Some of these have very respectable build volumes – but when it comes to “large-format,” the machines will need their own dedicated floor space. Large-format 3D printers have significant build volumes and are most often found in professional settings, like manufacturing facilities and R&D centers. Download Now
eBook - Efficient and Effective Production Support with 3D Printed Jigs and Fixtures
Jigs and fixtures offer manufacturers a reliable process for delivering accurate, high-quality outcomes, whether for a specific part or feature, or for consistency across multiples of parts. Although the methodologies and materials for producing jigs and fixtures have evolved beyond the conventional metal tooling of years past, their position as a manufacturing staple remains constant due to the benefits they offer.
