DonadonSDD TCD rupture discs are composite discs formed by four parts:
This disc has been designed especially to be mounted on road or rail tankers containing liquids and gas in static, cycling and pulsating conditions.
TCD discs react to excessive pressure with total opening in a few milliseconds. They are therefore recommended for valve protection. Supports may be provided for vacuum or counter-pressure protection.
