Nanhua Machinery developed the largest seven-kettle process polyester equipment

Recently, the world's largest capacity seven-kettle process polyester equipment was successfully manufactured at Sinopec Nanjing Chemical Machinery Plant and shipped to India's JBF company by waterway.

This set of equipment consists of 7 reactors and is the key equipment in India's JBF 900-ton polyester plant. The largest reactor, with a diameter of 5.988 meters, a length of 11.73 meters and a weight of about 140 tons, is currently the largest polyester reactor in polyester plants in Asia. As the only manufacturer in China capable of independently manufacturing complete sets of polyester equipment, Nanhua has won the India JBF company's manufacturing orders with its excellent performance, strong technical strength and service advantages, and finally won the competition with foreign manufacturers.

Compared with the conventional polyester equipment, the technical requirements of the equipment are higher. The largest single polyester reactor has 22 moving disks on the spindle. The radial runout must be controlled within 4 mm, and the installation accuracy is high. , manufacturing is very difficult. To this end, South Chemicals conducted a technical breakthrough and specifically designed the supporting fixtures to ensure the quality and progress of the equipment. The successful manufacture of this set of equipment indicates that the manufacturing technology of polyester complete sets of equipment of Nanhua has reached the international advanced level, and it has taken another step on the road to localization of large-scale equipment.
