Issues with steel stamps in pressure vessel manufacturing

2015-06-10View Original

Thread Content

Chapter 2, Article 4 of the \"Provisional Rules for the Management of Seals for the Safety Inspection of Boilers and Pressure Vessels\" provides clear specifications regarding the CS seal; however, many manufacturers have now switched to using TS seals. Has the regulation related to the former seal been abolished? The current version of the capacity regulations – 2013 – only includes a legend for the TS stamp in the certificate format. Is there any regulation that contains wording indicating that CS has been replaced by TS?
