I. Product introduction of Ginde PVC-U water supply
pipelines
I. Brief Introduction
Ginde has imported the most advanced technologies and equipment
from Europe. We adopt high quality PVC resins and imported
processing additives as the raw materials, with a scientific
formulas to produce PVC-U supplying water pipes and fittings. Sales
service net of our company products is all over China. It抯 one of
Asia抯 largest pipes production base.
Our company owns *6 PVC-U production lines and over **0
injection-molding machines to produce fittings. Our products are of
high quality, have various specifications and have passed strict
inspections. Our products have passed the ISO ***1 Quality
Management System Certificate and ISO ****1 Environmental
Management System Certificate. Our products match the GB/T
****2.*****6 and GB/T****2.*****3 standards respectively.
Properties of Ginde PVC-U water supply pipelines
a)Light weight: weight in unit length is only 1/6 of the cast-iron
pipes.
b)High strength: tensile strength comes to above *5MPa.
c)Less resistance: wall of the inner layer is smooth, prevents scum
buildup. The water pressure and discharge of PVC-U pipe is *0%
lower than cast pipes in the same diameter, and it can save the
cost of discharge power.
d)Corrosion resistance: it has the excellent resistance to the
corrosion caused by acid, alkaline, chemical and electricity.
Stains will not occur.
e)Simple installation: connect easily with rubber rings. It is easy
to carry out and seals well.
f)Long lifespan: under the normal working pressure, the lifespan
reaches to *0 years.
g)Sanitary and non-toxic: it accords with the drinking water
standard; the water is conveyed without secondary pollution.
h)Low cost: with lower cost of installation, transportation and raw
material, the total cost of the whole engineering makes the cost
*0% lower than cast pipes.
2.Major technical indicators of Ginde PVC-U water supply
pipeline
II. Production technique of Ginde PVC-U water supply
pipelines
1. Production equipment
The plastics molding extruder (for tubing) imported from Germany
KraussMaffei Company is designed and manufactured with the most
advanced technology at present in the world, which owns advanced
performances such as high-speed extrusion molding, automatic
cut-of-length, on-line hot-melt tube end expansion and PC
software controlled production processes.
The PC software (C4) for controlling the production processes can
be ted and set in advance according to process
specification, start-up time, temperature control criterion and
other conditions during production operations. Meanwhile, all the
modification of running speed, melt pressure, extrude output,
torque load and regulations of equipment motor and screw rod is
automatically monitored, recorded, stored for reading; it also
can alarm dangerous conditions, automatically shut down and
display suggestions or correcting instructions on the screen (it
can be read and used with three languages). Therefore, it can
guarantee fundamentally equipment in good condition as well as
normal operation of production processes.
Advanced mechanical structural design adopts Plano conic twin
screw with slenderness ratio of *6D, perfectly integrated with
scientific and special compression ratio process technological
design and mechanical structure. It owns prominent performances
such as secondary air exhaust, repeated compression, moderate
melting, high-speed extruding production process. Meanwhile, it
is equipped with large mixing equipment imported from Germany
Reimelt, which owns the functions of automatic metering and
convey, dust-free seal and uniform mixing and dispersing;
therefore it can guarantee the continuous process of production
automatically.
2.Raw material
PVC resins are adopted as the carriers; they own the high quality
performance such as accurate response to temperature, timing melt
and rapid absorption of additives when reducing the
intermolecular gravitational interaction of resins. Meanwhile,
our company has adopted the world top brand complex thermal
stabilizer – German “BEAR” which can capture, inhibit, absorb and
neutralize emitted hydrochloride, make double-bond addition
reaction with polyene and replace active and unstable atom
chlorine in molecules. Therefore, catalytic degradation and
oxygenolysis of resins under molting state can be effectively and
scientifically controlled.
