The Flawed-Cylinder Burst Test



J H. Smith


This report is a summary and compilation of the test results obtained during the development of the Flawed-Cylinder Burst Test. The Flawed-Cylinder Burst Test was developed as part of a cooperative project under the direction of the International Standards Organization Technical Committee on Gas Cylinders (TC 58)--Subcommittee on Cylinder Design (SC 3)--Working Group on Cylinder Fracture (WG 14). The Flawed-Cylinder Burst Test is a test method to evaluate the fracture performance of steel cylinders that are used to transport high pressure compressed gases.The concept and development of the flawed-cylinder burst test is described in the ISO Technical Report 12391 - Part 1 (1). The details of the test method and the criteria for acceptable fracture performance of steel cylinders are given in the ISO Standard ISO 9809:1999 Part 2 Clause 8.2.3 Flawed-Cylinder Burst Test (2). In this report, test results are reported for several hundred flawed-cylinder burst tests that were conducted on seamless steel cylinders that ranged in tensile strength from less than 750 Mpa up to about 1400 Mpa. The test method is intended to be used both for the selection of materials and to establish design parameters in the development of new cylinders as well as for an efficient quality control test to be used during the production of cylinders.
