Expansion Joints/Compensators

CASIC has supplied expansion joints for petrochemical and coal chemical industries since 1987, including major projects owned by SINOPEC, CNPC, CNOOC, Shenhua Group, BP, BASF, BAYER in China and other countries. CASIC is a regular sub-supplier of major EPC contractors, including SEI, CPECC, HQCEC, SSEC, LPEC, QPEC, WISON, LUMMUS, etc. Since the establishment of the joint venture AEROUSN-TOLA by AEROSUN, a division of CASIC, and Japan TECHNOFLEX in 1995, CASIC, relying on self-development and the patents and know-how from TECHNOFLEX, has become a world level supplier of expansion joints and a member of EJMA, a global recognized expansion joint association, supplying high quality expansion joints for FCC, Ethylene, Styrene, PE/PP, PTA, PDH, MTO units in petrochemical and coal chemical industries. Features CASIC has been devoted to the technology innovation of expansion joints for petrochemical and coal chemical industries, and can supply expansion joints for long-term reliable operation with the following features. 1. UOP technique for FCC units 2. LUMMUS technique for styrene and PDH units 3. Bellows materials: INCONEL 600/625(LCF), INCOLOY 800(H)/825, 4. duplex and super stainless steel, Titanium, Monel and Hastelloy 5. Refractory liner and hot wall/cold wall structures for refinery units 6. Two-ply bellows alarm device for critical applications (patent technology) 7. Avoid sweeping of medium deposit and filling bellows 8. Deposit welding of bellows and connection pipes to avoid welding corrosion of aeolotropic materials 9. Solution heat treatment of the bellows to improve anticorrosion property 10. Double-elbow expansion pipe to minimize stress in welding reducer 11. Floating ring design to reduce stress on the hot wall pipe
