Nantong Roland graphite equipment co., Ltd. (Vibration in Nantong Tong graphite equipment factory) is situated at the end of the head of the sea, the Yangtze River, Nantong city, called jianghaimingzhu. a few years ago, our number of Nanjing University of chemical technology and chemical mechanical and anticorrosive engineering students has initiated the establishment of a partnership of vibration Tong graphite equipment factory in Nantong (Nantong city, now Roland graphite eequipment co., Ltd.). relying on technical and scientific research and development capacity of the alma mater as the backing, combined with our extensive experience in the community, was to be of China chemical industry equipment advanced the concept of the Evangelist, as customers to the allies in the fight against corrosion.  factory after several years of development, have the conventional graphite heat exchanger million square meters, graphite pipe. various reaction vessels, tank, tanks, pumps more than more than 300 sets of overall production capacity, graphite, graphite heat exchanger pipes factory production equipment, graphite, graphite lined centrifugal pump, graphite film evaporator five classes, hundreds of varieties of products. while we adhere to the normal production of conventional products, almost every year to introduce innovative new products in the industry. such as graphite pump, underground heat exchanger type graphite reactor, 450 ℃ resistant high temperature graphite coolers, while in recent years combined with the user's needs, launches full range of process and device for purification of waste hydrochloric acid concentration, waste acid desorption-99.99% HCl gases, emissions <10 ppm  set of technology and devices, these devices in both technical and economic indicators in leading peer level.  I always insist on quality-centric, advanced technology as the Foundation, serve customers, mind of China chemical industry equipment advanced, available to our experiences with preservation of contribution to society.
