Scope

Scope: This standard specifies the packaging methods, packaging marks, and requirements for pressure vessels and vessel components manufactured as whole or in sections, as well as the relevant requirements for the protection and transport packaging of pressure vessels and their components. In addition to complying with the provisions of this standard, the protection and transport packaging shall also meet the technical requirements of the drawings. This standard applies to pressure vessel products manufactured in accordance with GB 150 and TSG 21; Main technical content: 3. Protection 3.1 Surface rust removal: For the outer surface of carbon steel and low-alloy steel vessels, the inner surface that can be rust-removed, and other surfaces requiring anti-corrosion coating, the rust should be removed. The surface rust removal should be carried out by spraying, blasting, or using manual and power tools, and care should be taken to avoid damaging the surface of the vessel during the rust removal process. Before rust removal, thick rust layers should be removed, and visible grease and dirt should be cleaned off; after rust removal, floating dust and debris should be removed. The steel surface after rust removal shall at least meet the requirements of St2 or Sa2 grade as specified in GB/T 8923-1988. After the surface rust removal, the residue inside the vessel shall be cleaned. 3.2 Application of anti-corrosion coating: The quality inspection department of the vessel manufacturing unit shall allow the application of anti-corrosion coating only after passing the inspection of various manufacturing quality, including surface rust removal. The metal surface before coating should be kept clean and dry. For uneven surfaces and scratches, they should be removed by grinding and smoothed over, and putty should not be used. The selection of anti-corrosion coating should be determined according to factors such as the nature and temperature of the medium inside the vessel, envir
