ASME Section XII Transport Tank Code was published in July 2004. This newly developed Code which provides rules for construction and continued service of pressure vessels used in transportation of dangerous goods via highway, rail or water. This paper presents a broad overview of Section XII. The main topics included in the paper are: scope and general requirements, materials and design, and fabrication, inspection and testing requirements.

The first edition of Section XII, “Rules for Construction and Continued Service of Transport Tanks,” was issued with the 2004 edition of the ASME Boiler and Pressure Vessel Code. Transport tanks are pressure vessels used for the transportation of dangerous goods via highway, rail, air or water. This paper provides an overview of the requirements of section XII.

Developed at the request of the US Department of Transportation, Section XII-Transport Tanks, of the ASME Boiler and Pressure Vessel Code addresses rules for the construction and continued service of pressure vessels for the transportation of dangerous goods by road, air, rail, or water. The standard is intended to replace most of the vessel design rules and be referenced in the federal hazardous material regulations, Title 49 of the Code of Federal Regulations (CFR). While the majority of the current rules focus on over-the-road transport, there are rules for portable tanks which can be used in marine applications for the transport of liquefied gases, and for ton tanks used for rail and barge shipping of chlorine and other compressed gases. Rules for non-cryogenic portable tanks are currently provided in Section VIII, Division 2, but will be moved into Section XII. These portable tank requirements should also replace the existing references to the outmoded 1989 edition of ASME Section VIII, Division 1 cited in Title 46 of the CFR. Paper published with permission.

ASME Section XII Transport Tank Code will have an impact on the regulations related to the construction and continued service of highway cargo tanks used in the transportation of dangerous goods. Modal Appendix 1 of this code specifically addresses these transport tanks, and is intended to replace a large portion of the DOT regulations currently governing how they are built and serviced. This paper presents a preview of Modal Appendix 1, one of the mandatory appendices related to cargo tanks, and how these changes will affect manufacturers and repair shops.

Ultra high voltage STEM has many inherent technical advantages over CTEM. These advantages include better signal detectability and signal processing capability. It is hoped that it will explore some new applications which were previously not possible. Conventional STEM (including CTEM with STEM attachment), however, has been unable to provide these inherent advantages due to insufficient performance and engineering problems. Recently we have developed a new 1250 kV STEM and completed installation at Nagoya University in Japan. It has been designed to break through conventional engineering limitations and bring about theoretical advantage in practical applications.In the design of this instrument, we exercised maximum care in providing a stable electron probe. A high voltage generator and an accelerator are housed in two separate pressure vessels and they are connected with a high voltage resistor cable.(Fig. 1) This design minimized induction generated from the high voltage generator, which is a high frequency Cockcroft-Walton type, being transmitted to the electron probe.

This study proposes a probability of detection (POD) model to quantitatively evaluate the capability of eddy current testing to detect flaws on the inner surface of pressure vessels cladded by stainless steel and in the presence of high noise level. Welded plate samples with drill holes were prepared to simulate corrosion that typically appears on the inner surface of large-scale pressure vessels. The signals generated by the drill holes and the noise caused by the weld were examined using eddy current testing. A hit/miss-based POD model with multiple flaw parameters and multiple signal features was proposed to analyze the measured signals. It is shown that the proposed model is able to more reasonably characterize the detectability of eddy current signals compared to conventional models that consider a single signal feature.
