(CRC) operating principle consists in 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 sleeve at operating pressure with a guaranteed quality unlike the sleeves installed  without prior creating the pressure.

• (CRC) is operable at  temperatures from -60˚С to +200 С ˚

• It is possible to manufacture sleeves operable  at temperatures up to +400 С˚

• (CRC) is successfully used to  repair underwater offshore pipelines.

• In most cases, installing (CRC) is an alternative to the spool  cut.
