DIN 4809-1-1986 热水加热装置用弹性化合物材料制膨胀件(橡胶膨胀件).最高工作温度为100℃和最大压力为10巴
Compensators made of elstomeric compound materials (rubber-compensators) for warm water heating-plants; up to a maximum operating-temperature of 100 C and a maximum pressure of 10 bar
Compensators used in heating-plants reduce noise and vibrations caused by heating pipes as well as compensate movements of pipes. Movements and vibrations are compensated by elastic deformations of the rubber material. These elastic deformations can be reduced by lenth-boundaries and bracings. Compensators which meet this standard are expected to have an adquate quality and life-time.
