Lianyungang Zhongtong Composite Material Machinery Manufacturing Factory China (Mainland)

Founded in 1957, Lianyungang Zhongtong Composite Material Machinery Manufacturing Factory was formerly an enterprise under the direct administration of Chinese Chemical Industry Ministry. We were one of the 156 large-scale projects during the First-Five-Year Plan period, and a manufacturer of chemical industrial equipment of the ministry as well. During the past 50 years, we have developed greatly and been one of the key professional enterprises in the trade of composite material for manufacturing the FRP products. We are composed of 6 branches, which are the offices of assembly and oxygen generating, caption foundry, forging, riveting, welding, metal machining, with the annual output value of RMB 400 million. Our company is also a group-member of China's Association for FRP Industry, and has passed the international quality control system certification of the GB/T19001--2000--ISO9001:2000. The followings are the main equipment of machine works: A complete set of production line for manufacturing FRP pipes; A complete set of computer-controlled production line for manufacturing FRP pipes with sand adding; Winding machines with sand adding; 400mm winding machines; MT6 winding machines; MT4 winding machines; On-site reeling machines; Fully automatic finishers; Hydraulic strip machines; Lining machines; Far infrared solidifying stations; Stirring machines; Dust removers; Hydraulic test machines; Spare parts & accessories of the above-mentioned equipment for manufacturing FRP products; Strip machines; Bell mouth rings; Steel moulds in various specifications, such as 5mm-4,000mm in diameter, and the length of 200mm-18,000mm.
