Product Description

3LPE Steel Pipe Field Joint Coating Corrosion Protection Heat Shrinkl Shrinkable Sleeve 
 

HUASHIDA-3LPE heat shrinkable sleeve is composed of cross-linked polythylene back and special heat melt adhesive. Heat melt adhesive has good bonding with PE back, steel pipe and epoxy prime. When heating PE back shrinks, adhesive layer melts, and closely wraps around pipe joints. It forms together with epoxy primer a firm and continuous anti-corrosion body. It is resistant to corrosion, wear, impact, UV and aging, easier to be operated.


 
Application area:
It is mainly used for 3LPE pipe fiele joint coating, joint closure for oil gas pipeline and water pipeline.




Feature of our heat shrinkable sleeve HUASHIDA-3LPE:
1.fast shrinkage speed,
2.good waterproof performance,
3 good anti-corrosive performance,
4.long service life

5.using pure PE material and imported adhesive for ensuring the quality

Heat Shrink Sleeve Installation Instruction

Bare area surface cleaning
Mixing primer
Preheating
Applying primer

Installation of heat-shrinkable sleeve:

Installation of closure patch

The sleeve is fully recovered when all of the following have occurred:

1. The sleeve have fully conformed to the pipe and adjacent coating;
2. The are no cold spots or dimples on the sleeve surface.
3. Weld bead profile can be seen through the sleeve.
4. After sleeve is cold, adhesive flow is evident on both edges.
