Overview of Development in Forged Flange Industry
Jul 29, 2020
A flange, also called a rim or ridge, is mainly used to connect tubular parts. Flanges are widely used in mechanical parts, such as petrochemical pipelines, metal pressure vessels, water and sewage pipelines of buildings, municipal water supply pipelines, ships, electric power and other industries.According to different raw materials used, flanges can be divided into carbon steel flanges, stainless steel flanges and alloy steel flanges; according to different manufacturing processes, flanges can be divided into forged flanges and cast flanges. Forged flange is mainly produced by free forging or die forging process; casting flange is a flange manufactured by casting process.
At present, China's forged industry has made great progress in equipment level, forging technology and processing technology. The quality and performance of products have been greatly improved. Due to low labor cost, forged flanges produced in China have a strong competitive edge in the world, and the export quantity has reached a high level in recent years. Germany, Japan and other industrial developed countries have few domestic flange manufacturers due to high labor costs, and the flange products needed are mainly imported from developing countries such as China, India and Brazil.
