摘要：The present patent relates to the sector of surge tanks for pumps and boilers,and particularly concerns a new flange made of plastic and fibreglass for assembling on surge tanks The flange has a
dome-like geometrical shape, that is concave on the underside, designed to reinforce it and to reduce the amount of material needed to
make it. Said flange is distinctive in that it is shaped so as to ensure perfect geometrical compatibility with the surge tank on which it is assembled and the tightness of the butyl (or other material) seal.
