RGV Casing Spacer for Pipe OD 1000mm~2000mm

RGV Casing Spacer

The RGV casing spacer is designed to support and center a carrier pipe with Diameeter 1000mm ~2000mm inside a larger casing pipe. Its modular segment construction allows the spacer ring to be assembled around the pipe, helping maintain the required clearance during installation and reducing direct contact between the carrier pipe and casing.

Applicable Pipe Diameter1000mm ~ 2000mm.
Stable Pipe SupportRaised support points help keep the carrier pipe centered and properly separated from the casing.
Application-Based SelectionSelect the required configuration according to the nominal casing size and carrier pipe outside diameter.
