Pipe Structure
Every cross of steel
wires is welded
HDPE Steel wire mesh

Coupler inside diameter = Pipe outside diameter
Pipe 1 Electrofusion Coupler Pipe 2
Jointing surfaces are melted using Electrofusion Machine
Performance Comparisonto Normal PE Pipes
NOTE:
Normal PE pipes use DN, which is outside diameter.
Roobuck PE pipes use Inside diameter.
For comparison, the diameter of one pipe must be
converted so both pipes are compared in either OD or ID.
Example:
Normal PE Pipe Roobuck Pipe
(outside D: 280) (Outside D: 275)
1) Large inside section area
2) Less weight for pipes >DN200
So:
-- Easy installation
-- Less support for raised pipeline
3) High pressure
Up to PN40 (4MPa)

4) Better long-term hydrostatic strength
Most internal stress is born by steel mesh so HDPE is released
Steel wire mesh hold HDPE together
(Every cross over of the wire is welded)
5) High Rapid Crack Propagation Resistant and
Environment Stress Crack Resistant
6) Higher environment temperature
When temperature rises, PE strength is reduced quickly, but steel only changes very slightly in the range of 0-100oC.
7) Flexible along pipeline
-- Steel has much higher elasticity modulus
-- Steel mesh configuration makes it flexible in the axis direction
Suitable for curved pipeline
8) Smooth inner wall in low resistance
Bead No bead
Hot Plate Electrofusion
for normal PE pipe For Roobuck pipe
9) Very strong connection
9.1) Much larger welding area
Normal PE pipe: welding pipe wall section
Roobuck Pipe: Welding pipe surface
9) Very strong connection
9.3) Steel skeleton reinforce for fitting
Steel skeleton is stronger than steel mesh
Connection is stronger than pipe itself !
9.2) Double wall thickness at welding area
Electrodes to Steel skeleton
generate heat
Installation Comparisonto Normal PE Pipes
1) Less weight of pipes
-- Most pipes can be moved in hand
-- Easy transportation
2) Less weight of welding machine
Can be carried in hand – about 20kg
3) Less welding time
Total welding time about 30 min
4) Easy for high rising installation
Welding machine is on the ground and only wires connect to coupler
5) Multi-point installation
No need to wait for cooling to go to next point
6) Easy operation of welding machine
Automatic setup and simple menu
7) Reliable
Less effect from dust, raining or wind
All installation data are saved in USB
8) Less man power
Significantly less labour cost
9) Less fuel consumption
Small generator and crane
Cost ComparisonTo Normal PE Pipes
1) Lower pipe cost
-- Use smaller pipes owing to large inside section area
-- Use smaller pipes in high pressure
2) Lower installation cost
Easy and quick
3) Lower maintenance cost
-- Pipe reliable, robust and long lifetime
-- Traceability: steel is easy to detect
-- Simple repairing using electrofusion
Typical Applications
-- Transportation of Ore Pulp and Tailings
-- Transportation of Corrosive Materials in Mining, Metallurgy, and the Chemical
Industry
-- Transportation of Water under high Pressure.
-- Transportation of Oil and Gas
-- Special environment such as high temperature, curved pipeline, vibrating area, etc
