Aquajet Systems Introduces Aqua Centralizer For Tunnel and Pipe Applications

Published: 9/12, 2019

Aquajet Systems introduces the Aqua Centralizer, designed for effective cleaning and removal of concrete, paint, rust and coatings along an entire section of horizontal, vertical or inclined tunnels and pipes. The Aqua Centralizer works in conjunction with Aquajet’s Aqua Cutter Hydrodemolition robots and high-pressure Aqua Power Packs to provide strategic concrete removal in roadbuilding, wastewater and industrial plant applications.

The Aqua Centralizer uses elements of the Aqua Spine as the base for the unit while incorporating technology from the Circular Power Head attachment for concrete removal and cleaning applications. This includes a 360-degree ring and robotic power head with a 25-degree adjustable lance angle and variable stroke oscillation. The power head offers adjustable working angles from 0 to 360 degrees and automatic indexing along the spine rail, minimizing downtime from repositioning and optimizing productivity.

Combined with one of Aquajet’s Power Packs, which provide a pressure up to 40,000 psi (2,758 bar), this flexibility offers contractors the power and precision to effectively clean steel pipes and remove concrete inside tunnels and pipes.

The modified Aqua Spine that makes up the base of the Aqua Centralizer can span up to 19.7 ft (6 m) between a pair of triple support wheels. Supports feature adjustable caster wheels that are designed for 4.9- to 9.8-ft (1.5- to 3-m) diameter tunnels. For additional reach, the ring and circular power head can be mounted in front of the support wheels.

Centralizer rings are available in three sizes—3.2 ft (1 m) for 4.9- to 6.5-ft r (1.5- to 2-m) diameter tunnels; 4.9 ft (1.5 m) for 6.5- to 8.2-ft (2.0- to 2.5-m) tunnels; and 6.5 ft (2 m) for 8.2- to 9.8-ft (2.5- to 3-m) tunnels. The powerhead adjusts up to 10 in (25 cm) to facilitate the diameter ranges.

The Aqua Centralizer is easily assembled, allowing for maximum productivity. A single bolt attaches the power head to the circular rail, with the spine roller attaching to the central spine rail the same way. Additionally, the attachment’s power head can be reversed for effectively removing concrete on the outside of pillars and pipes.

The Aqua Centralizer is one of several efficiency-enhancing attachments available for use with Aquajet’s Aqua Cutter robots. It can be operated using Aquajet’s Power Pack and stored, along with the robot, in the Power Pack container for easy transportation to and from the jobsite. It also provides a secure location for the duration of the job.
