The CRC operating principle consists of the compensation of pipeline internal pressure by means of external contact pressurization at a significant bolt joints torque value (up to 700 Nm).

This provides an opportunity to mount sleeves at operating pressures with guaranteed quality unlike the sleeves installed without previously creating pressure.
