Description of 3PE Anticorrosion
Steel Pipe Production Line:
Introduction of 3PE Anticorrosion Steel Pipe Extrusion Machine:
3PE
Steel Pipe anti-corrosion Production Line includes as following process
flowing:
Steel tube inspection--Steel tube surface skim-- Steel tube
intermediate frequency preheating Peen-forming degusting --Internal and external
dust sweep-- Degusting check --Dust processing→Medium frequency induction
heating-- Epoxy powder coating-- AD adhesive coating --PE coating --Inspection.
3PE Anti-corrosion steel pipe is widely used in oil pipelines, natural gas
pipeline, heating pipe, water supply pipe.Characteristics of 3PE anticorrosive steel tube:
1) polyethylene
anticorrosion properties is admirable, but tolerance in the natural environment
of the existence of the various corrosion;
2) high quality and price
ratio;
3) polyethylene insulating performance is wonderful, and in dry
conditions and long-term immersion electrical performance under the condition of
basic unchanged,can effectively prevent the stray current corrosion caused by
electrochemical;
4) microbial corrosion resistance and deep roots plant thorn
ability, won't happen plant roots through phenomenon;
5) high strength, can
be directly with contain more than Φ 25 mm in diameter of the artificial pieces
of gravel soils and not cause any damage to backfill;
6) coated tubes overall
flexural ability, generally allow cold bending 1.5 tube diameter;
7)
production process for all mechanized, stable product quality, be helpful for
the comprehensive quality control;
8) polyethylene coated steel pipe
production of all raw materials for the production of large enterprise, a
reliable source, quality assurance;
9) long service life and can be used in
more than 50 years.
Features of 3PE anticorrostion coating machine:
1. Peen-forming derusting equipment . The function is mainly clear rust of
steel pipe surface.
2. Electric-magnetic heating equipment . It is Qingdao Friend Plastic
Extrusion Technology Co.,Ltd 's patent . It is compared with medium frequency
heating equipment .the electric-magnetic heating equipment has some advantages .
The first the heating speed of electric-magnetic heating equipment is faster
than medium frequency heating equipment . The second , if electric-magnetic
heating equipment is compared with medium frequency heating equipment , the
electric-magnetic heating equipment can save 40% to 60% electric energy
.
3.Epoxy powder thermal spray equipment . The function is mainly coat a
layer epoxy powder on the steel pipe surface . The function of a layer epoxy
powder prevent steel pipe oxidation. the thickness of epoxy powder is
(60—80μm).
4.Adhesive coating equipment . It include extruder and die head . the
extruder adopt electric-magnetic heater which can save 40% to 60% electric
energy for customer ! The function is mainly extrude adhesive. The thickness of
adhesive is (170—250μm);
5.Polyethylene coating equipment . it include extruder and die head . the
extruder use electric parts which brand is word famous brand. (
Siemens/Omron/Schneider ) . The function is mainly extrude Polyethylene. The
thickness of polyethylene is about 2mm to 5mm. Adopt electric-magnetic heater
which can save 40% to 60% electric energy for customer . Adopt PLC control and
simple operation .Material of screw and barrel: 38CrMoAlA, nitrogen quenched
which the thickness layer 0.4-0.7mm; Hardness of screw barrel: >940 HV;Unique
grooved structure feed bush with force cooling system that is specially designed
by Friend co. which can increase output at 15-20%; Material of die head is 40Cr,
the surface and channel of mould is chrom-plated;
6. Water Cooling Equipment. It includes motor/support/ vacuum pump/transport
devices. The function is cooling and transport 3PE anticorrosive steel tube
.
