Road crossing

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 offer the following pipe spacer systems...

a – 60;  a – 60 Clip;  a – 120;   A;  Ad;  a – NT; A – NT;  BC;  B – NT;   C

We deliver our casing spacers as ready-to-install rings adapted to the circumference of the pipe.

At the request of our clients, due to logistic considerations we can deliver spacers already integrated in pipe segments, or as partially-assembled segments.

AKWEDUKT pipeline spacer systems are divided into 3 groups–MINI, MIDI, MAXI, depending on the load carrying capacities.

MINI

• a-60–for carrier pipes between ø 20 and ø 150, maximum static load per spacer ring up to120 kg
• a-60 CLIP carrier pipes between ø 20 and ø 150, maximum static load per spacer ring up to120 kg
• a-120–for carrier pipes between ø 100 and ø 300, maximum static load per spacer ring up to 250 kg
• A and Ad–for carrier pipes between ø 80 and ø 300,maximum static load per spacer ring up to 200 kg
• a-NT–for carrier pipes between ø 80 and ø 350,maximum static load per spacer ring up to 300kg

MIDI

• A-NT–for carrier pipes between ø 100 and ø 500, maximum static load per spacer ring up to 500 kg

MAXI

• BC–for carrier pipes between ø> 400, maximum static load per spacer ring up to1500 kg; for h>80 mm, and maximum static load per spacer ring up to1800 kg for h≤80 mm
• B-NT–for carrier pipes between ø> 350, maximum static load per spacer ring up to 1500 kg
• C–for carrier pipes between ø> 500, maximum static load per spacer ring up to 3200 kg

CHOOSING A SPACER

1) Minimum spacer height „h min ”: the distance between the carrier pipe OD or carrier pipebell/flange and the casing should be between 5 and 15 mm.

2) Maximum spacer height„h max ”: should allow the carrier pipe to be inserted together with the spacers into the casing pipe, so that the upper clearance between casing and spacer ring should be at least 20 mm.

The greater the clearance, the easier the insertion of the carrier pipe.

We recommend:
• installing two rings of spacers next to each other at the end as well as at the front of the casing.

• for bell mouth pipes we recommend installing one ring of spacers directly behind the bell and one ring directly before the bell.

Distance between spacer rings
• The maximum distance between spacer rings (L max) depends on the maximum load per ring and the medium in the carrier pipe. We usually recommend a distance of 0.8 to 2.0 m.

The pipe manufacturer or the pipeline designer may recommend a different distance than the one suggested in our tables.
The most important aspects of calculating the distance between spacers are safety and the stable operation of the pipeline.
