Burst Strength of Type 304L Stainless Steel Tubes Subjected to Internal Pressure and External Forces
Session Dates
17 Oct 1996
Abstract
The findings of an investigation concerning the burst strength of cold-formed Type 304L stainless steel tubes subjected to internal pressure and static external forces are reported in this study. The use of cold-formed stainless steel longitudinally welded tube in pressurised processes in industry are limited due to the belief that seamless tubes have superior resistance to internal pressure. The primary objective of this study was to experimentally and theoretically describe the failure criteria for thin-walled longitudinally welded Type 304L stainless steel tubes subjected to internal pressure and static external point loads and torsion loads. Due to the diversity of the pipe manufacturing process, problem areas which were most likely to cause failures were identified. A microscopic study was done of the weld region where failure was expected in order to support the test results. It was found that cold-formed longitudinally welded Type 304L stainless steel tubes could attain very high bursting pressure values and could compete with seamless tubes in this respect. It was also found that the internal pressure was the most important criteria in tube failure and that the effect of static external forces could be neglected to a certain extent.

Burst Strength of Type 304L Stainless Steel Tubes Subjected to Internal Pressure and External Forces
The findings of an investigation concerning the burst strength of cold-formed Type 304L stainless steel tubes subjected to internal pressure and static external forces are reported in this study. The use of cold-formed stainless steel longitudinally welded tube in pressurised processes in industry are limited due to the belief that seamless tubes have superior resistance to internal pressure. The primary objective of this study was to experimentally and theoretically describe the failure criteria for thin-walled longitudinally welded Type 304L stainless steel tubes subjected to internal pressure and static external point loads and torsion loads. Due to the diversity of the pipe manufacturing process, problem areas which were most likely to cause failures were identified. A microscopic study was done of the weld region where failure was expected in order to support the test results. It was found that cold-formed longitudinally welded Type 304L stainless steel tubes could attain very high bursting pressure values and could compete with seamless tubes in this respect.
