kwick-ZIP® HDX / HDXT Series casing spacer
 
Designed for Medium to Heavy Weight Pipe in Cased Crossings
Recomended for use on pipes with a Diamater 100mm OD & greater
 
A non corroding, non-metallic casing spacer for Pipe-in-Pipe (PIP) applications such as slip lining and cased crossings for all medium to heavy weight pipe materials including steel, DICL, MSCL, GRE, PVC and HDPE.
 
HDX Range Suitable for all diameters from 100mm OD to 1600mm OD and beyond by addition of multiple segments.
 
HDXT  Suitable for all diameters from 300mm (11.81”) OD and beyond by addition of multiple segments.
 
•Made from Kwik-ZIP’s engineered thermoplastic blend with high flexural strength, high temperature resistance, low co-efficient of friction, abrasion resistance and outstanding chemical resistance.
• Integrated rubber grip pads under collars to prevent slippage. No requirement to pre-wrap pipe.
• Load sharing suspension system allowing heavy loads to be shared across multiple runners reducing point loading and increasing the overall load capacity of the spacer.
• Minimizes spacer weight bearing capacity and reduces point loading via a unique load sharing runner system.
• Ability to combine different runner heights in the same spacer ring to assist in borehole grade correction.
• Larger diameters are accommodated by joining additional segments.
• Requires only a flat blade screwdriver for installation.

Load sharing
Using a unique “load sharing runner” system, each HDX segment maximises its weight bearing capacity by distributing the pipe load across multiple runners.
 
This reduces point loading at any one location, boosting and optimising the overall support capacity of the spacer exponentially as pipe size increases. The “load sharing runner” system also delivers a suspension and dampening effect, reducing the transfer of potentially damaging vibration and movement from the outer casing to the carrier pipe.
 
This may be beneficial in tectonically active regions or high traffic areas where ongoing external vibration affects the outer casing.
