Casing spacers

AKWEDUKT casing spacers are used for inserting carrier pipes into casings. Our products are made of high-quality heavy duty material (PEHD, PEMD, PELD, POM). We offer various spacer systems which address a wide range of pipe sizes and weights and are designed to meet the needs of pipeline design and construction businesses.

Our end seals are an easy, time-saving and safe method of sealing casing ends. AKWEDUKT casing spacer and end seal system is the perfect solution for pipeline intersections, road crossings etc. It provides maximum protection in areas where a pipeline passes under or is buried beneath an obstruction.

We deliver the a-NT spacers as a ready-to-install rings adapted to the circumference of the pipe or as single elements for self-assembly.

A single a-NT-type spacer element consists of 12 supports and is suitable for installation on a  ø160 carrier pipe. In order to obtain the correct ring length of spacers for other diameters, we join and/or cut out the appropriate number of supports, in accordance with information provided in the a-NT-type spacer selection table.

ASSEMBLY: assembling the spacers of a-NT system consists in tightening the ring on the pipe by means of fasteners (steel or
plastic). The multi-element version is made by connecting several basic elements.

Method of joining of single NT-type spacer elements:


The installation of a-NT spacers comprises of the tightening of ring on a pipe using two M5 bolts.
