AZ Modular Casing Spacers
A sectional pipe support and isolation system for centering carrier pipes inside larger casing pipes.
Product Overview
AZ modular casing spacers are designed for carrier pipes with outside diameters from 100 to 400 mm. Each spacer ring is assembled around the carrier pipe using three to six curved support segments and stainless-steel bolts.
The modular construction makes the spacer easy to assemble around the pipe before it is inserted into the casing. Five runner heights are available to suit different annular-clearance requirements.
