As an important basic component in the petrochemical industry, the quality and performance of petrochemical forgings are directly related to the safety and service life of the entire equipment. In order to ensure that the quality and performance of petrochemical forgings meet the requirements, countries have developed corresponding standards and specifications. This paper will compare and analyze the domestic and foreign standards of petrochemical forgings, aiming to help enterprises better understand the requirements of domestic and foreign markets, improve product quality and market competitiveness.
China has developed a series of national standards and industry standards for petrochemical forgings, such as GB, JB and so on. These standards have made detailed provisions on the material, size, mechanical properties, chemical composition, inspection methods and other aspects of petrochemical forgings. The formulation of domestic standards is mainly based on the actual needs and national conditions of China’s petrochemical industry, focusing on practicability and operability.
Foreign standards for petrochemical forgings mainly include American ASTM, European EN, Japanese JIS and so on. These standards have high visibility and influence in the world, and are widely adopted and recognized. The formulation of foreign standards usually pays more attention to scientific, advanced and international, emphasizing the docking with international trade and transnational cooperation.
Comparative analysis of domestic and foreign petrochemical forging standards
Material requirements: Domestic and foreign standards for the material requirements of petrochemical forgings are basically the same, requiring the use of high-quality steel or alloy materials. However, foreign standards have stricter requirements on the chemical composition and mechanical properties of materials to ensure the reliability and durability of products.
Dimensional tolerance: Domestic and foreign standards have different dimensional tolerance requirements for petrochemical forgings. Domestic standards are usually more relaxed, allowing a certain size deviation; Foreign standards have more stringent requirements for dimensional tolerances, emphasizing the consistency and interchangeability of products.
Mechanical properties: Domestic and foreign standards for the mechanical properties of petrochemical forgings requirements are also different. Foreign standards usually require products with higher strength and toughness to adapt to harsher working environments and higher working pressures. On the basis of meeting the basic mechanical properties, the domestic standard pays more attention to the practicality and cost effectiveness of the product.
Inspection methods: There are also differences in the inspection methods of petrochemical forgings in domestic and foreign standards. Foreign standards usually adopt advanced non-destructive testing technology and equipment to carry out comprehensive and strict testing of products; The domestic standard is relatively simple in inspection methods, mainly relying on traditional visual inspection and destructive test.
Environmental protection and safety: With the improvement of global environmental awareness and strict safety standards, domestic and foreign standards for the environmental protection and safety performance of petrochemical forgings are constantly improving. Foreign standards are usually more stringent in this regard, requiring products to have higher environmental performance and more comprehensive safety safeguards.
Through the comparative analysis of domestic and foreign standards of petrochemical forgings, it can be seen that there are differences in material, size, mechanical properties, inspection methods and environmental protection and safety. This requires enterprises to fully understand and comply with the relevant standards and norms of the target market when developing domestic and foreign markets to ensure that product quality meets the requirements. At the same time, enterprises should also strengthen technological innovation and research and development investment, improve product quality and performance levels, in order to adapt to the changing market demand and competitive environment.
