Reply rewards! ---------------------------------------------- The past ten years have been an era of great development for China's chemical industry. The emergence of many new processes, new products, and new equipment has also led to a great development in my country's chemical equipment, which has also promoted the rapid development of the petrochemical industry. Here we have collected and sorted out some of the achievements and breakthroughs made by my country's equipment companies in the large-scale and localization of equipment. Welcome everyone to share, discuss, and exchange, cheer for Made in China, and cheer for chemical equipment! ========================== On January 9, 2020, Daming Heavy Industries Valmet’s RAPP duplex steel digester equipment, 4 large duplex steel digesters, were shipped overseas. At the beginning of 2019, Daming Heavy Industry successfully provided several projects for Valmet. The projects covered heat exchangers, carbon steel storage tanks, stainless steel vessels, duplex steel digesters and other equipment, and were highly praised by customers in Chile, Indonesia, Brazil and other countries. The four large-scale duplex steel digester equipment shipped successfully this time are important equipment in the pulping process, with a diameter of 5.6m and a length of 20 meters. The main materials are European grade 1.4462 and 1.4307 duplex steel. Its processing is quite difficult. The Valmet project team of Daming Heavy Industry overcame many technical difficulties during the production process, such as welding deformation, thin-walled cylinder section deformation and other difficulties, and successfully submitted the answer to the customer. Both the manufacturing quality and delivery time were recognized by the Valmet team.
