Design specification for metal and non-metal expansion joints

    Design specification for metal and non-metal expansion joints

    The design and calculation of expansion joint products strictly follow the technical specifications in the American Expansion Joint Manufacturers Association standard EJMA, GB/T12777-2008 General Technical Conditions for Metal Bellows Expansion Joints, GB16749-97 Pressure Vessel Waveform Expansion Joints, GB/15700-1995 General Technical Conditions for PTFE Wave Compensators, etc., and computer-aided optimization design is used;

     The nominal diameter of the ripple compensator series products produced by the company varies from Φ 32mm-12000mm, can meet the design and manufacturing of any cross-sectional size of rectangles. The working pressure ranges from vacuum to 10Mpa, and the design temperature is -196 ℃ -1300 ℃, which can meet various engineering needs both domestically and internationally.

   The product is widely used in industries such as electricity, desulfurization and environmental protection (thermal power, nuclear power, hydropower, thermal power, etc.), steel metallurgy, refining and oil storage and transportation, chemical industry (sulfuric acid, hydrochloric acid, hosphate fertilizers, ethylene, etc.), cement, urban centralized heating, high-rise buildings, military industry, food and light industry, electronics, etc.
