Pre Insulation Pipe Joints PE Ageing Resistant Heat Shrinkable Tape
It is mainly composed of base material and hot melt adhesive. Our
company adopts unique hot melt adhesive formula to ensure the
adhesive strength of the product in use and thus ensure the
construction quality. Optimization of the design of the new heat
shrinkable tape (set) is easy to site construction, fast shrinkage,
short operating time, low construction costs, with excellent water
vapor permeability, chemical corrosion resistance, insulation and
aging resistance and other properties, is the ideal material for
pipeline anticorrosion thermal insulation system. Among them, three
layers of reinforced fiber type heat shrinkable tape (set) is in a
layer of substrate, a layer of adhesive coating between a layer of
reinforced fibers, adhesive strength and higher tensile strength,
contraction faster, the effect is also better. Mainly used for oil
and gas pipeline joints to fill the mouth of the anticorrosion,
patching, can also be used for pipeline damage repair. This product
is suitable for 3PE steel pipe, 2PE steel pipe, epoxy powder
coating, thermal insulation pipe jacket skin and polyethylene
drainage and sewage pipeline pipeline patching, patching.

Advantages of Huashida heat shrinkable sleeve
A. Heat shrinkable sleeve base material for the production of raw
materials, raw material production from the outside looking highly
than other manufacturers bright. Other manufacturers of raw
materials accounted for 50% -60% recycled materials accounted for
50% of the
B. Stronger baking resistance, lap joints do not crack, convenient
construction
C. My company's hot melt adhesive using EVA hot melt adhesive,
adhesive strength, high peel strength glue
D. Shrinkage speed
E. Good sealing performance
F. Qingdao Huashida production of heat shrinkable tape (sets), the
use of adhesive are purchased from the United States DuPont, Japan
Sumitomo, South Korea, Hanwha and other international brands, EVA
content of 28%!
Feature
1.Fast shrinkage speed,
2.good waterproof performance,
3 good anti-corrosive performance,
4.long service life, convenient transportation and fast
construction.
2. 3Layer Fiber
reinforced PE heat shrinkable tape (sleeve) is composed of
cross-linked polyethylene back, a middle layer of fiber and special
heat melt adhesive an. The 3 layer reinforced sleeve gives better
shrink ratio, and better strength. It is resistant to corrosion,
wear, impact, UV and aging, easier to be operated.
Application area:
It is mainly used for Hollow wall spiral pipe, corrugated pipe and
metal reinforced corrugated spiral pipe etc.
TEST PROCEDURE
1. Clean the steel pipe and heat it by fire till over 80 ºC
2. Paint the steel pipe with Primer (mixed with A&B)
3. Fire heat the heat shrink sleeve, be attention to start heating
from middle of the sleeve, but act from up and down, and gradually
move from middle to two sides of sleeve, in order to drive air out
of the sleeve, after finish heating, the good result is that there
is about 1-2mm hot adhesive melt at the edge of sleeve.
TEST RESULT
1. Test result after cooling about 40 minutes.
Peel strength to primer is over 100N per 2cm(till the end of the
spring balance). at 30.7ºC
Co-adhesive: Half-half.
2. Test result after cooling about 24hours.
Peel strength to primer is over 172N per 2cm at room temperature
about 30.7ºC
Co-adhesive: Half-half.
3. 2. Test result after cooling about 24hours.
Peel strength to primer is over 9.2kg/90N per 1cm at room
temperature about 30.7ºC
Co-adhesive: Half-half.
