Scope

Main Technical Content: 3.2 Storage and Management Methods After the welding samples of pressure vessel products are stored, and after the samples complete the inspection and evaluation, they need to be placed in designated storage areas for safekeeping. The sample management personnel should maintain a storage logbook, the format of which is shown in Appendix A. The logbook should clearly reflect the sample number, sample specifications, the corresponding equipment serial number and model, as well as relevant diagrams and other notes deemed necessary by the management personnel. During transportation and storage, the samples should be handled with care to prevent damage. The welding samples of pressure vessel products should be stored in indoor warehouses by category. Indoor storage and stacking should take measures to prevent rust, moisture, and contamination, and the samples should be sorted and stored by batch number and specification. The bottom layer of the sample stack should be elevated, with a height of more than 300mm from the ground. Samples generally should be arranged according to the equipment they come from, and protected by methods such as wrapping in paper or plastic, packing in boxes, or dipping in varnish, etc., based on different material and anti-corrosion requirements. After the welding samples of pressure vessel products are stored, if they need to be retrieved for inspection, they should be taken out with the consent and supervision of the management personnel. After inspection, they should be promptly returned to their corresponding storage locations, and the number and specifications should be checked by the management personnel. For the destruction of welding samples of pressure vessel products, if the corresponding equipment products have been shipped out within three months and there are no special requirements from the equipment users or manufacturers, they can be destroyed and disposed of after applying for and obtaining a
