FAQs
Frequently Asked Questions
What is the Heat Shrinkable Vented Thin Wall Tube used for?
It is used for:
- Wind power anchor bolts
- Automotive parts and U-bolts
- Corrosion protection on threaded fasteners
How is it installed?
Clean and degrease the surface, position the part, then shrink it with a gas torch or a hot-air gun: keep the heat moving round it with a smooth, brushing motion so it recovers evenly without scorching. Start at one end and work steadily along to the other.
Which standards and test methods are quoted for it?
These, with the values in the Technical Specification on this page:
- ASTM D638
- ASTM D570
- ASTM D792
- ASTM D2671
- ASTM D2671B
- ASTM D150
- ASTM D257
- IEC 216
