Special Equipment Industry

　　I the bellows expansion joint development work began in 1969, according to the requirements of national defense equipment, to undertake the boat with the development of metal bellows, successively developed DN550 bellows expansion joint, turbine inlet steam damping flexible over, high temperature and high pressure metal bellows expansion joint, etc. At present, I can make no strengthening U and U type and Ω corrugated pipe, corrugated pipe materials for austenitic stainless steel, corrosion resistant alloy, cupronickel, industrial pure titanium, etc. Circular expansion joint size is (- 4800 mm, rectangular expansion joint can be arbitrary size.

This series of products have been standardized, has been formed including: YZM, CSRW, ZM, PC, MZ, YD, SN, CQ, CY, HR and so on ten series of products; At the same time, I also can be provided according to the requirements of customers special design expansion joint. I can also be designed according to user requirements to provide the line compensation, corrugated pipe material selection, expansion joint bellows damage analysis and life evaluation and bellows performance test of technical advice and technical services, and developing special-purpose expansion joint project tasks. Products are sold in addition to the domestic outside the Tibet, Taiwan, macau all provinces, municipalities, autonomous regions and countries such as Sudan, Iraq.
