||1) It can be widely used in the
drainage and sewerage piping of municipal

in factories, sewerage treatment plants and other
strip pitch can be easily adjusted by a pitch
mechanism so as to achieve the best ring stiffness
and the lowest unit weight.
● The forming and
bending of the strip and forming of the composite
pipe is synchronically controlled by PCC control
system, avoiding disadvantages of pulling off,
piling up and breaking of the strip during
forming, ensuring 100% of the finished product
● A special composition device makes the
forming of the spiral strip and inner pipe stable,
with adjusting function both for inner and outer
● A professional PCC (B&R,
Austria) control system is adopted for high
automation, reliable running and easy operation.
● Long-distance communicative function can
realize tele-diagnosis and maintenance
||(1) Light weight, high ring
stiffness, low cost, with strong market
competitive power. Under the same diameter and
ring stiffness, the lightest weight per meter can
be obtained for the pipe over 800 mm of diameter
and materials can be cut down by 20%－60% in
comparison with those of the hollow winded pipe,
the moulding ribs winded pipe and the double wall
(2) Easy and reliable
connecting, by thermo-melt coupling (for the
purposes of drainage, sewerage and ventilation) or
thermo-shrinking film, or outer half-block with
(3) Excellent low temperature
resistance, being installed between －60℃～ 60℃．
(4) High complete strength, bearing large
axial tensile force and circumferential ring
(5) Good soil adaptability. It has a
good adaptability without breaking for resisting
earth settlement and movement because of high
coefficient at rupture which is up to 500%.
(6) Excellent flowing performance. The flow is
bigger than that in cement pipe under the same
diameter because of the small flow resistance.
(7) Excellent wear and corrosion resistance.
Its life is longer than that of the cement pipe.
(8) Being green product for environmental
protection, without any pollution.
|At present, the demand of drain pipe exceeds
its supply and is becoming a hot field of
investment. The large size spiral steel pipe
production extrusion line equipment and its
technology for the corrugated pipe winded with
steel strip were developed in the 1990’s. They are
now widely used in many fields in the developed
countries, especially for water, drainage,
sewerage piping in industries and agriculture in
USA, Canada, Japan, Korea and the European
countries. An extrusion line for the corrugated
pipe winded by steel strip is newly presented us,
combining international advanced technologies,
with a diameter range of ID 800 mm—3,500 mm.
