Universal composite reinforcement sleeve SMART LOCK (UKMT)

Studying the fiberglass structures evolution and using the analysis of existing methods to repair pipelines, specialists of «NefteGazDiagnostika» LLC have developed the composite pipeline sleeve SMART LOCK (UKMT).This product has been commercially available since 2008.
The sleeve consists of two half-shells manufactured by unidirectional winding of glass roving on stainless steel flanges. The principle of SMART LOCK operation — the pipeline internal pressure compensation by the external contact pressure developed at high tightening torque of bolted connections. The technology allows SMART LOCK installing at operating pressures with guaranteed quality, unlike the sleeves installed without preloading.
