Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 245-2008 "metal pipe crimping test method", compared with GB/T 245-2008, the main technical changes as follows. - modified the expression of "scope" (see chapter 1); --- Change the title of Chapter 3 to "Test Principle" (see Chapter 3); - the test procedure is specified in more detail (see 6.3); - delete the curl rate calculation formula (see 6.7,.2008 edition of 6.7 note). This standard uses the translation method equivalent to ISO 8494..2013 "metal pipe crimping test method". This standard has made the following editorial changes. - correct the international standard error, change the symbol "b" in Table 1 to "β"; Figure 1 adds the title. This standard is proposed by China Iron and Steel Industry Association. This standard is under the jurisdiction of the National Steel Standardization Technical Committee (SAC/TC183). The drafting unit of this standard. Changshu Entry-Exit Inspection and Quarantine Bureau, Metallurgical Industry Information Standards Institute. The main drafters of this standard. Lu Shuyuan, Wang Weizhong, Dong Li, Zhu Yibo, Hou Jie, Shi Wei. This standard replaced the previous version of the standard release. - GB 245-1963, GB 245-1982, GB/T 245-1997, GB/T 245-2008. Test method for curling of metallic materials

1 Scope

This standard specifies the crimping test method for determining the plastic deformation capacity of circular cross-section metal pipes. In addition to the relevant product standards, this standard applies to the diameter of not more than 150mm, wall thickness of not more than 10mm metal tube. 2 symbols, names and units The symbols, names and units used in this standard are specified in Table 1 and Figure 1. Table 1 Symbols, names and units Symbol name unit aa wall thickness mm D metal pipe original diameter mm Du metal tube maximum curling diameter mm L The original length of the specimen mm R Crimping die fillet radius mm Beta top angle (°) a The symbol T is also used in the pipe standard to indicate this parameter. a) flaring b) curling Figure 1 Schematic diagram of crimping test ...
