Heavy-caliber twin –wall spiral pipe
,the new type of twin-wall pipe, is produced by extruding polyethylene,
the main material, turning polyethylene material into two things
the square pipe and the material of “工”shape, then making them
together through twining ,the processes are as follows: Firstly,
turn polyethylene by squeezing into round pipe, then finalize
the design in the vacuum in order to make the round pipe into
square pipe; secondly, twining spirally square pipe with the
melted things squeezed by another machine on the shaping machine,
finally, weld the gaps between pipes and heavy-caliber twin-wall
spiral pipes come into being .The product, free from pollution,
energy-saving, is a new type of high-tech building material..。

| Adopt Japanese Panasonic FP2
serial ultrafast large capacity PLC control systems, import
the frequency converter and digital direct current governor,
is it gather many pieces of data dynamic picture to form
through man-machine interface dialogue , realize non-linear
rotational speed and linear rotational speed switch over.
The work is steady, it is high to control the precision |
| · |
Japan NAISFP2 ultrafast large capacity PLC control system; |
| · |
Realize that the non-linear rotational speed and linear
rotational speed are switched over; |
| · |
Automatic and temperature-controled, the type is in
charge of pushing out of , melting the glue to push out
of , twine shaping , cut moving ahead simultaneously,
autotracking is controlled; |
| · |
Long- range data entry , procedure revises , controls
diagnosing and getting rid of trouble long-rangly . |
| · |
Pipe pharmaceutical producing machine, accuse of feeding
in raw material and adjusting controlling warmly rapidly; |
| · |
The vacuum finalizes the design , the temperature is
controlled; |
| · |
Realistic alarm of temperature curve ,etc.; |
| · |
Melt glue person who push out of, warm to accuse of
, transfer speed , temperature curve to show alarm ,etc. |

1、Products use various kinds of serial sewages
, heavy-calibre drain pipes of waste water.
2、The heavy-calibre is sent and managed to pilot
a ship into harbour , supply water.
3、Agriculture pilots a ship into harbour, arranges
and inculcates and sends off managing with the channel
.
4、 Various kinds of building bridge pillar sleeve
pipes .
5、The pipeline is buried in advance in the expressway
.
6、 Large capacity cask, the granary and septic tank
are made.
7、The colliery ventilates, the post and telecommunications
is managed.
8、Chemical industry , mine are used in the transport
of the fluid and exhaust. |

1, The intensity is high, the structure is unique
, rich flexibly , resists to press shock- resistantly.
2, Light, construction is simple and convenient,
weld the craft simply , with low comprehensive fabrication
cost of project.
3, Corrosion-resistant , resist chemistry , nonpoisonous
and pollution-free, environmental protection is
of good performance.
4, In charge of wall level and smooth wear-resisting
to decrease strong , rub obstruction little , heavy
to circulate ability.
5, Resist and shine , use and guarantee for more
than 50 years burying longe-livedly , cold- resistantly.
6, Pipe was brought by special-purpose , firm and
reliable , has not leaked to weld to join.
7, The diversification , simplifying the operational
procedure , project dependability of the specification
is high. |
