HDPE Pipes

Product Overview

DN 100–500mm floating pipeline system combining HDPE dredging pipe with high-buoyancy HDPE floaters. Ideal for river, lake, and marine dredging, sludge discharge, and offshore pumping. Floater buoyancy 90–1350 kg per pair. Each HDPE floating dredging pipe section is engineered as a complete buoyant module, keeping the slurry line afloat under full load while the orange floaters stay visible on the water surface.

Key Features

High Buoyancy Design: Foam-filled or air-chamber floaters keep the HDPE floating dredging pipe afloat under full slurry load.
High-Visibility Orange: Marine-grade UV-stabilized orange floaters stay bright for safe navigation around the floating line.
Abrasion & Corrosion Resistant: The HDPE floating dredging pipe resists slurry wear, saltwater and chemicals in marine service.
Quick Assembly: Segmented HDPE floating dredging pipe plus bolted floater clamps allow fast on-site installation and relocation.
Flexible & Durable: The HDPE floating dredging pipe withstands waves, currents and thermal movement without cracking.
Wide DN 100 – 500 Range: Eight floater sizes match the HDPE floating dredging pipe diameter with 90 to 1350 kg net buoyancy per pair.

Production

Raw Material

The HDPE floating dredging pipe is extruded from certified PE100 black compound per ISO 4427, while floaters are molded from HDPE shell with PE foam or air-chamber filling.

Assembly Process

PE100 pipe sections are butt-fusion welded into continuous floating lengths, then matched with precision-molded floaters and locating clamps.

Quality Control

Each HDPE floating dredging pipe floater is buoyancy-tested to guarantee net lift, and pipe welds are inspected for fusion integrity before delivery.

Applications

River and lake dredging slurry discharge lines use the HDPE floating dredging pipe for afloat slurry transport.
Marine sand and gravel pumping operations rely on the HDPE floating dredging pipe for stable offshore discharge.
Offshore dewatering and discharge pipelines install the HDPE floating dredging pipe as a quick-deploy floating line.
Port, harbor and land reclamation projects choose the HDPE floating dredging pipe for visible, relocatable slurry routing.
