Note: 1. The special requirements of bellow joints can be customized according to user's drawing. Flange standard is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber ball of joint expansion can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the joint expansion above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the joint expansion shall be installed with anti falling device.
