Marine container forging is an important part of the ship, its quality and performance standards and specifications are very important to ensure the safety and operation of the ship. This paper will introduce the technical standards and industry specifications of Marine container forgings, including international standards and standards formulated by industry organizations, as well as their requirements for forging materials, manufacturing processes and quality control.
introduction
The technical standards and industry specifications of Marine container forgings are formulated in order to ensure the safety and performance of ships and improve the quality and reliability of forgings. These standards and specifications are the guidance for the manufacture, use and maintenance of forgings, which have important significance and influence on the entire Marine industry.
International standard
2.1 ISO Standard
ISO (International Organization for Standardization) has developed a series of standards related to ships, including the quality requirements, specifications and test methods of steel, aluminum alloy, nickel alloy and other forgings. For example, ISO 839-1:2017 “Steel casting and forging parts Part 1: General requirements” and ISO 9001:2015 “Quality Management system – Requirements”.
2.2 ASTM Standard
ASTM (American Society for Materials and Testing) has developed many standards related to Marine forgings, including the chemical composition, mechanical properties, heat treatment and other requirements of steel, aluminum alloy, nickel alloy and other materials. For example, ASTM A668/A668M-17 “Heat Treatment of Carbon Structures for Steel forgings” and ASTM A953/A953M-17 “Process Code for Casting and Forging of Non-deformed aluminum Alloys Using Conventional Temperature or Low Temperature Quenching grinding”.
3.1 International Maritime Organization (IMO) Regulations The IMO is a specialized agency of the United Nations responsible for developing and promoting international standards and regulations for navigation. Its specifications for Marine forgings mainly include material selection, manufacturing process, installation and maintenance requirements. For example, IMO MSC.210(81) “Preventive Maintenance of Cover plates and flange forgings” and IMO MSC.6(48) “Requirements specified in Global Solutions and Safety Technical Documents for Manufacturing Standardization”.
3.2 Classification society specifications
The Classification Society is a member organization of the International Federation of Classification Societies (IACS), responsible for ship certification and technical specification development. The specification requirements for Marine container forgings mainly include materials, design, manufacturing process and quality control. For example, China Classification Society (CC) “Container forgings manufacturing inspection procedures” and American Classification Society (ABS) “Materials and welding Marine forgings technical specifications” and so on.
Forging material and manufacturing process requirements
The technical standards and industry specifications of Marine container forgings put forward strict requirements for forging materials and manufacturing processes. Forging materials should meet the chemical composition, mechanical properties and metallurgical structure and other indicators, such as carbon steel, alloy steel, stainless steel, etc. The manufacturing process requires detailed regulations on forging, heat treatment, surface treatment and processing to ensure the accuracy, strength and durability of the forgings.
Quality control requirement
The technical standards and industry specifications of Marine container forgings put forward strict requirements for quality control. Including non-loss testing, mechanical properties testing, size measurement, heat treatment quality control, surface quality control, etc. Ensure that the quality of the forging meets the standard requirements to prevent the occurrence of defects and failures.
conclusion
The technical standards and industry specifications of Marine container forgings are very important to ensure the safety of ships and improve the quality and reliability of forgings. The regulations of international standards and industry organizations, as well as the requirements of classification societies, strictly regulate the forging materials, manufacturing processes and quality control. The shipping industry should strictly abide by these standards and specifications, improve the quality of forgings, and ensure the safety and smooth operation of ships.
