Anti-Corrosion Steel pipe
Anti-corrosion coating steel pipes, through the preservative process, is to prevent
steel pipes from corroding or to slow down the corrosion in the chemical or electro
chemical reaction during the transportation and application. According to China’s
statistical data, our domestic economical loss resulting from pipes corrosion is over
280 billion every year, and the annual global loss of pipes corrosion reaches 500
billion. The anti-corrosion coating pipes can stop and retard the erosion effectively,
so the technique is widely used in the industry.

◆IPN 8710
Consist of aliphatic polyurethane prepolymer and epoxy resin, pigments, additives,
and solvents. The coating is specialized in the anti-corrosion surface of the
equipment contact by food and drinking water, water transportation and
distribution pipes, and the drinking water tank.
This paint is a kind of interpenetrating network polymer, which can be aggregated
at room temperature, complementing each other. With the character of non-toxic
coating, high solids, and low viscosity, this new type anticorrosive paint has a
capability of strong adhesion, high strength, abrasion resistance, hydrolyzation
resistance, corrosion resistance, water resistance and weather resistance. Moreover,
it has a few requirement of rust removal on the steel surface, and the temperature
may be in the range of -20 to 120℃.

◆BE Epoxy Powder
BE epoxy powder anticorrosive coating is to spread epoxy powder on the surface of
steel pipes to form a protection film at a time by using the electrostatic paint
spraying technique. The coating has advantages of simple coating operation, clean,
good impact resistance, bending properties, and temperature resistance.
Standard: AWWA C210; SY/T0315-2005, QCNPC 38-2002, QSY-XQ9-2003 etc.

◆2PE/3PE
The PE corrosive structure: the inside layer epoxy power (FBE>100um), the middle
adhesive (AD 170~250um), and the outside layer polyethylene (PE 2.5~3.7mm).
The three materials integrated well and attached firmly to the steel pipe so as to
form a strong anti-corrosive coating. Outside diameter is at a range of Φ60~Φ
1420.

◆ Coal Tar Epoxy Coating
i. Consist of epoxy resin, coal tar pitch, anti-rust pigments, additives and modified
amine from. The coating has advantages of rapid drying, strong adhesion, good
flexibility, and easy two-component packaging, and easy construction. It can also
resist acid, alkali, salt, water, oil and etc.
ii.Combined characteristics of epoxy resin’s high mechanical strength, strong
adhesive force, and chemical resistance characteristics with that of bitumen’s water

erosion, anti-microbial, and plant roots resistance, the coal tar epoxy has a high
performance on anti-corrosion insulation, as well as a good resistance of chemistry
and water.
iii.The coal tar epoxy coating can be applied to the corrosion of both pipelines of oil,
gas and water, and the equipment of water, gas, pipelines, refineries, chemical
plants, sewage treatment in the factory, also be widely used on the offshore oil
drilling platforms, underwater portion of the ship, mine and underground
equipment.

◆Cement Mortar Lining Coating
Cement mortar lining can ensure a safe and abundant water supply for water
customers for many years to come. Cement will also extend pipe life by inhibiting
the corrosion of ferrous materials and preventing future rust and tube regulation
build up.
Water pipe through the centrifuge tube wall spraying machine forms cement
coating of 8 to 16 millimeter, a major role in the protection of water quality. It is
a durable, cost-effective, time proven choice for protecting steel pipe interiors for
over a Century. Cement mortar lining coating is appropriate for above or
below-ground applications in potable and reclaimed water systems.

◆GZ-2 Polymer Coating

GZ-2 polymer coating is a new type of anti-corrosion coatings which is made from
acrylic epoxy, polyurethane, chloride olefins, makings, non-toxic anticorrosion
pigment and additives. GZ-2 polymer coating is mainly used for inside or outside
anticorrosion coating of drinking water pipeline corrosion and metal concrete pool,
outer wall and inner wall anticorrosion coating of water tank, gas cylinder, pipelines,
storage tank, power plant, chemicals, fertilizers, pharmaceutical and other
industrial plant and equipment. It has advantages of non-toxic, strong adhesion,
fast drying, and easy construction, else, it is good at resisting acid, alk

Polyurethane Foam Insulation Pipe

1. The brief introduction of Polyurethane Foam Insulation Pipe
Polyurethane foam insulation pipe is much welcomed by the people in the

application, for its long-lasting corrosion-resistant aging characteristic, and
therefore have great market demand exists, steel jacket steam pipe insulation and
therefore for the production of polyurethane insulation has a very a large amount
of production requirements. For the production and processing of polyurethane
insulation, the need for treatment for a specific purpose and structure. For the inner
tube and the outer tube insulation implementation, usually between two direct
perfusion foamed slurry, a molding foam.

2. Specifications: DN50mm-DN1400mm,

3. The composition of Polyurethane Foam Insulation Pipe:

The pipe in side,(pipe work), silicone high temperature paint, sliding bracket, high
temperature glass wool, aluminum foil reflective layer, an air insulation layer, coat
steel pipe, winding fiberglass coating (or coal tar epoxy paint coating).

4. The features of introduction of Polyurethane Foam Insulation Pipe

In the following 350 ℃, centrifugal glass wool is an excellent thermal insulation
material, light weight, stable geometry, multilayer staggered joint bandage,
effective in reducing heat loss, coat surface while controlling measures to prevent
the generation of cold bridges, so that the jacket coating temperature control is
guaranteed. After the water has dried and the physical properties and geometry
characteristics can be fully restored. This feature enables the construction of the

pipeline to adapt to conditions of high water table areas, bring great convenience
to the construction, reduce construction costs.
