Seamless PE Electro Fusion Tape for Preinsulated Pipe Joints
Product Description
Huashida Seamless HDPE Electro Fusion Sleeves is a pipe interface welding material: high-quality HDPE sheet
is cut into sheets that meet the required length, width, and
thickness according to actual needs, and then combined with special
electric heating wire mesh through special heat sealing
equipment. It combines the high tensile toughness strength and shrinkage rate of both electrofusion sleeves and heat shrinkable sleeves.
Application scenarios
1. District thermal heating system construction,
2. Pre-insulated pipes field joint welding and oil
pipes joint welding;
3. Preinsulated bonded pipe system for directly buried
hot water networks;
4. Three PE/PP layers with foam jacket insulation
pipes connection;
5. Steel pipes anti-corrosion.
Operating Instructions
Construction precautions for seamless heat shrinkable joint sleeves
1. Remove dirt. Wipe the surfaces at both ends of the pipe clean and gently sand
it with sandpaper.
2. Preheat the temperature at both ends of the pipe to 60°-70°, take off the
adhesive tape and place it in an appropriate position, then remove
the isolation film.
3. The self-adhesive tape should be placed at the appropriate position on the outer edge of
the seamless heat shrinkable joint sleeve. Use a ruler to find the
right position and make the marking for pasting.
4. Pull back the seamless heat shrinkable joint sleeve to the
appropriate position.
5. Bake the edges 10cm high over high heat. First, bake the top
until it softens, then the sides, and finally the bottom. After
baking one side, bake the other side. It's best for two people to
bake each other at the same time. Repeat this process back and
forth
6. During on-site field construction, pay attention to the
crosswind and flame direction. The hot spot must not be exposed to
the suspended area (in the middle of the joint).
7. It is essential to allow the softened heat shrinkable joint
sleeve that has been baked to cool down for a certain period of
time. Only in this way can it shrink more tightly
8. Finally, seal both ends with heat shrink tape and inject
polyurethane in time. If the product is exposed to the sun for a
long time or is placed on the pipe without construction, it will
shrink, causing it to seize up with the pipe and be impossible to
remove. Therefore, construction and storage should be carried out
in accordance with the requirements!
9. Do not bake horizontally. Instead, swing the spray gun up and
down to bake
10. Store the product in a cool and well-ventilated place, away
from direct sunlight
11. Place horizontally to prevent deformation.
