Both union material of type A and type B 's are malleable iron,Both rubber material can be Neoprene.EPDM,NBR.
Both pressure of type A and type B 's are Class150,PN10/16,JIS 10K/16K
Size: 1 1/4"-120" (DN32-DN3000)
Material of Rubber: Neoprene, EPDM, NBR.
Type B expansion joint is separated from union, which can be disassembled and replaced. The connection method of A & B type is the same,with the threaded connection.
(1)Reduce pipeline system vibration and noise
(2)Good sealing, light weight, easy installation, long service life
(3)Solve the problem of axial movement, transverse movement, angular movement
(4)Acid resistance, alkali resistance, corrosive resistance, oil resistance, heat resistance
When flange expansion joints are installed to connect with raised face flanges, the use of ring gaskets are needed to prevent metal flange faces from cutting the rubber bead during installation.
