DANSK DS/EN ISO 13341 PDF

This standard specifies the essential procedures to be followed when connecting cylinder valves to gas cylinders. It applies to all valve and cylinder combinations connected with ISO screw threads given in the normative references. It defines routines for inspection and preparation prior to valving for both taper and parallel screw threads. Torque values are given in Annex A for steel and aluminium gas cylinders including composite cylinders with steel or aluminium connectors. NOTE ISO/TR 11364 lists the valve to gas cylinder threads in use worldwide. This report gives details of the thread identification codes, whether the threads are interchangeable with ISO threads and if the taping procedure and torque values specified in this standard can be used. The technical report will give clear guidance for the method and torque for all listed inline threads, which are not interchangeable.
