| Abstract | Pipes are used as construction elements, to transport liquids and gas in pipelines and as storage containment’s for gas and liquids. A very cost efficient method to fabricate larger diameter pipes with heavier wall thickness is the DSAW process. In many applications in the above listed fields the pipes are exposed to fatigue loads. Several design codes and standards exist which consider SAW pipes for the different applications. Depending on the loading conditions the stress concentration resulting from the weld of the DSAW pipe but also from the connecting welds in the structure leads to a significant reduction in lifetime. This reduction is accounted in the different design codes. To utilize the cost efficient DSAW pipe also for applications which so far could economically only be served by seamless pipes a method was developed to reduce the stress concentration in the area of the long seam. This method provides pipes with a lifetime similar to a seamless pipe by still maintaining the competitiveness of the DSAW manufacturing process. A test program to qualify this method for Cargo Tank Cylinders for Compressed Natural Gas Transportation on vessels was accomplished in order to proof that the measures taken are effective. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
