About Taftan Louleh
Taftan
Louleh, produces corrugated pipes, whose inside diameter measures
from 200 mm to 1200 mm. Taftan Louleh, produces its pipes by using
IDSC technology which is a leading technology in producing double
wall PE corrugated pipes in the world. Corrugated polyethylene pipe
usage has grown extensively in the last 20 years. Most countries
are now specifying this product as the pipe of preference.
Corrugated polyethylene pipe offers important engineering design
characteristics such as; enhanced hydraulic flow, unparalleled
chemical resistance, good abrasion resistance, joint integrity and
superior strength.
The
complete production line has been purchased from Corma Company in
Canada and these machines are the most modern machines of their kind
in the world, and an amount of 90,000,000,000 Rials, has been
invested on this important product. It’s also expected that by
manufacturing these pipes, the needs of all the nearby cities and
villages of Iran will be satisfied.
Production
Process:
The raw material used to produce these pipes is HDPE (High Density
Poly Ethylene). The Poly Ethylene is initially extruded by 2
extruders, which one of them is in charge of melting and injecting
the inner layer, and the other extruder, is responsible for the
outer one. The melted PE will go through a “Die Head” and after
passing through particular channels, will be form the inner and
outer layers of the pipe by “Vacuum Forming” system. The melted PE
will be sucked up towards the surface of the mould blocks by a
vacuum pump, and that’s how the outer section is shaped.. Then the
inner and outer layers will be welded and then the hot pipe will
exit the machine, which will be further cooled off down stream.
Technical Features
1) In-line
Coupling: For the first time in Iran, we produce our pipes, with
coupling along the pipe. So the Spigot and Bell sections are
embedded in the pipe length, so no more need to have Belling machine
downstream and so, much higher production speed. Also, the coupling
section itself has 2 layers (Double Wall In-line Coupling), so is
much stronger in terms of ring stiffness. Therefore, when required
to couple the pipes together, two sections are pushed towards each
other and the O-ring inside the coupling will seal the coupled
section properly.
2) Strength and
Ring Stiffness: We currently produce our pipes in 2 Standards of SN4
and SN8 according to “prEN13476”, which is a European Standard in
Corrugated pipes. SN4 corresponds to Ring Stiffness of 4 KN/m^2 and
SN8 equals to 8KN/m^2. Also we offer our products according to
another Standard which is “DIN16961”. So according to this standard,
we manufacture our pipes in 31.5 KN/m^2 and 63.0 KN/m^2 of Ring
Stiffness.
3) Super
Cooling: in these machines, air-cooling of the pipes begins
immediately once molding is complete. As soon as the pipe shrinks
away from the mold block surface, cold air is channelled through the
vacuum forming slits in one half of the mold block, around the pipe
in the gap between it and the mold block surface, then out through
the vacuum forming slits in the other half of the mold block. Super
cooling results in productivity improvements of 25-100%.
4) Mould
Quick-Return (MQR): this system increases production speed by
extending the molding track with mold blocks from the return track.
It also allows the corrugator to operate with just a partially
filled mold track.
5) Vertical
Design: The machines used for producing these pipes, feature
vertical construction. This design is extremely user-friendly and
has been proven for more than 30 years.
