Overview

The plain-ended HDPE pipe is the same PE100-grade dredging pipe supplied without flange fittings, for lines that are joined in the field. It addresses the standard complaints about pipe in dredging service, abrasion, corrosion, weight and efficiency, and carries slurry, mud and sand sediment removed from oceans, lakes and rivers at 0.6-1.5 MPa in outside diameters from 200 to 800 mm.

Who it is for

Contractors laying long HDPE runs that are joined in the field and do not need bolted flange connections at every section.

Key benefits

High toughness with extremely high elongation at break, resisting impact, compression and bending without brittle failure
Excellent corrosion resistance and chemical stability for complex water conditions and media
Very low maintenance cost with no anti-corrosion treatment required
Low transport and installation cost with no heavy lifting equipment needed
Flexibility accommodates complex terrain such as gullies and changing riverbeds
Plain ends suit field-joined runs without flange hardware

Problems it solves

What goes wrong without it

1

Steel line in a dredging environment corrodes and has to be protected, inspected and eventually replaced on that account alone.

2

Heavy pipe sections need lifting plant and the schedule that comes with it; HDPE can be handled and connected manually.

3

A rigid line forced across a gully or a moving riverbed either needs fabricated bends or ends up stressed. HDPE follows the ground.

Construction and technical features

Material: high-density polyethylene, virgin PE100-grade or higher pellets
High mechanical strength with chemical resistance
Plain ends for field jointing
Designed for slurry, mud and sand sediment transport
Third-party inspection available on request

Quality control

Strict material selection using virgin PE100-grade or higher polyethylene pellets
Dimensional checks on outside diameter and wall thickness
Pressure testing to the specified working pressure
Third-party inspection agencies can be invited according to customer requirements

Where it is used

Long permanent onshore runs joined in the field
Channel clearing works where the line stays in place across the contract
Floating lines supported on PE floats with jointing done onshore
Terrain with gullies or riverbed movement that a rigid line cannot follow

Customisation

Outside diameter 200-800 mm
Section length 5800 mm or 11800 mm
Working pressure specified within the 0.6-1.5 MPa band
Flanged version available where bolted connections are required

How it compares

Choose the plain-ended pipe for long runs joined in the field, where flange hardware at every section adds cost without adding value. Choose the flanged version where the line is reconfigured between phases and sections need to come apart without fusion equipment. Material, diameter range, length and pressure ratings are identical.

Selection and use notes

Confirm the field jointing method and equipment before ordering plain-ended pipe
Check the duty against the 0.6-1.5 MPa working pressure band
Allow for HDPE's flexibility when setting supports or float spacing
Store sections out of prolonged direct sunlight before installation

FAQ

Questions buyers ask

Why order pipe without flanges?

For long runs joined in the field, flange hardware at every section adds cost and weight without being needed. Where the line has to come apart, the flanged version is the better choice.

What sizes are available?

Outside diameter 200-800 mm in 5800 mm or 11800 mm lengths.

What are the pressure ratings?

0.6-1.5 MPa working pressure and 1.8-4.5 MPa burst pressure.

How does HDPE compare with steel pipe on cost?

Maintenance cost is very low and no anti-corrosion treatment is required, and transport and installation cost less because no heavy lifting equipment is needed.

What material grade is used?

Virgin PE100-grade or higher polyethylene pellets.

Can it handle difficult terrain?

Yes. Its flexibility allows it to accommodate complex terrain, such as crossing gullies or adapting to changes in riverbeds.
