Pipe has three layer PE antisepsis structure: the first layer with
epoxy powder (FBE> **0um), the second layer with adhesive (AD),
**0 ~ **0um, the third layer with polyethylene (PE) 2.5 ~ 3.7mm.
integration of them and solid steel pipe make form a good coating.
Diameter range *0mm****0mm, wall thickness 2.***8mm, which is a
good anti-corrosion method, generally can improve the service life
of *0 years, not only extended the replacement cycle of the
underground plumbing, and significant cost savings for the provides
a strong role in nation-building. 3PE
anti-corrosion is the most commonly used method of
anti-corrosion, in addition to 2PE, 2PP, 3PP, their manufacturing
process is similar to but different raw materials, this
anti-corrosion characteristics of the simple fabrication process,
the preservative effect, inexpensive pipe manufacturing industry
generally agree that corrosion
3PE anticorrosive steel pipe characteristics:
1，very high tightness,which can greatly save energy, reduce
costs, protect the environment in long-term operation.
2, strong corrosion resistance, the construction side simply speed,
the service life can be up to ****0 years.
3, with good resistance to corrosion and impact resistance, low
water absorption, the PE (less than 0.*1%) at low temperatures.
4, high strength epoxy, PE absorbent and hot melt adhesive
softness, etc., have high corrosion reliability.
Coated steel pipe is the pipe based as the matrix melt
spray or adsorption food-grade epoxy powder coating orPE raw
materials at high temperature curing from new materials, through a
special process in the wall.
Coated steel pipe is with excellent corrosion resistance and
frictional resistance. Epoxy coated steel pipes is used for water
supply and drainage, sea water, warm water, oil, gas and other
medium of transportation, and polyvinyl chloride (PVC) coated steel
pipe is for drainage, sea water, oil, gas and other medium of
transportation.
Product features: The steel pipe is PE (modified polyethylene) hot dip or EP (epoxy) products both inside and outside coating with excellent corrosion resistance. The coating itself has a good electrical insulation and does not produce electrical erosion. Low water absorption, high mechanical strength, low coefficient of friction to achieve the purpose of long-term use. besides, effectively preventing the destruction of plant roots and soil environmental stress.
Inside and outside the coated steel pipe is dissolving layer
melt in the pipe wall thickness 0.5 ~ 1.0mm polyethylene (PE)
resin, ethylene - acrylic acid copolymer (EAA), epoxy (EP) powder,
non-toxic polypropylene (PP) steel-plastic compound pipe, or
non-toxic polyvinyl chloride (PVC) and other organic form, it not
only has the high strength of steel pipes, easy to connect,
resistance to water flow impact, but also to overcome the steel
pipe water corrosion, contamination, scaling and plastic pipe
strength is not high, and poor fire performance shortcomings of the
design life of up to *0 years. The main disadvantage of not
bending, thermal processing and welding cutting operation is to
install the application manufacturer, the cut surface with some
non-toxic room temperature curing adhesive brushing.
BLACK STEEL PIPES
Black steel:
Black iron is the uncoated steel and is also called as black steel.
When steel pipe is forged, a black oxide scale forms on its surface
to give it the finish which is seen on this type of pipe. Because
black steel is subject to rust and corrosion, the factory also
coats it with protective oil. Those black steel are used for
manufacturing pipe and tube, which will not rust for a long time
and requires very little maintenance. It is sold in standard
**-foot lengths TBE.
Usages of black steel pipe::
Black steel pipe is widely applicable for ordinary uses in water,
gas, air and steam, black steel tubes and pipes are utilized for
gas distribution inside and outside the house and for hot water
circulation in boiler systems. It is also used for line pipes in
oil and petroleum industries, for water wells and for water, gas
and sewage purposes. It is not used for potable water or for drain
waste or vent lines.
Black steel pipe:
Black steel pipes and tubes are cut and threaded to fit the job.
Fittings for this type of pipe are of black malleable (soft) cast
iron. They connect by screwing onto the threaded pipe, after
applying a small amount of pipe joint compound on the threads.
Larger diameter pipe is welded rather than threaded. Black steel
pipe is cut either with a heavy-duty tube cutter or cutoff saw or
by hacksaw. When steel pipe is forged, a black oxide scale forms on
its surface to give it the finish which is seen on this type of
pipe. Because steel is subject to rust and corrosion, the factory
also coats it with protective oil. Those black steel are used for
manufacturing pipe and tube, which will not rust for a long time
and requires very little maintenance. It is sold in standard
**-foot lengths TBE.
