Pipe Weights / Pipe Collars

Anchoring solutions for marine applications

Precast concrete pipe collars or pipe weights are essential components for securing plastic pipes in marine applications.

These versatile pipe weights offer several key benefits…

Assembly and deployment

On-shore assembly
Pipes can be prepared on land, with weights added to achieve the desired buoyancy.

Controlled floatation
Empty pipes are weighted to allow air-filled sections to be easily floated to their intended locations.

Precise anchoring
Sufficient weighting ensures pipes remain securely anchored once submerged.

Functionality

Pipe stabilisation
Concrete collars hold pipes firmly in place underwater.

Sinking capability
When necessary, collars can be used to sink pipes to the sea floor.

Design Considerations

Crack prevention
The Plastic Pipe Institute recommends precast concrete to minimise cracking during handling and installation of PE (polyethylene) pipes.

Symmetrical design
Collars are typically crafted with symmetrical shapes, such as those we produce, to prevent twisting during the submersion process.

By utilising precast concrete pipe collars, marine installations can achieve greater stability and longevity for underwater pipeline systems.
