A: No. The PDS-1120 is the User’s Design Specification (input). The U-1 (Manufacturer’s Data Report) is the final report of construction (output). The Manufacturer transfers data from your PDS to the U-1.
One of the most referenced sections in the PDS-112013 deals with residual strength curves. It provides step-by-step numerical examples showing how to calculate the remaining strength factor (RSF) for a pressure vessel containing a surface crack or a through-thickness crack.
Q: Is ASME PDS-112013 the same as API 579? A: Not exactly. ASME PDS-112013 is a supplement to the joint document API 579-1/ASME FFS-1. It provides examples that support the API/ASME joint standard.
Q: Does the PDF include software? A: No. The PDF includes tables, flowcharts, and calculation sheets, but not executable software. You must perform the math manually or use third-party FFS software.
Q: Can I use the 2013 edition for a 2025 project? A: Technically, yes, if your engineering contract or jurisdictional regulations allow the "2013 Edition with all addenda." However, for new design or re-rating, the latest edition (currently FFS-1 2021) is recommended.
Q: I received a "ASME PDS1106.pdf" – is that the same? A: No. PDS-1106 pre-dates 2013 and references the 2007 FFS standard. Always match the year (13) with the correct parent code edition.
In the early 2010s, many engineering firms converted massive binders of ASME code into searchable PDFs using Optical Character Recognition (OCR). Sometimes, the software misread headers. A genuine document like ASME PTB-11-2013 (Pressure Vessel Guide) or ASME PTC 11-2008 (Fans) could be garbled.
The standard mandates that manufacturers provide an instruction manual that includes:
