What is poly - merization cured coating? 4. :Three main products that are transported by pipelines? 5. Examples of non-convertible coatings 6. There are two ways to tell If the hot applied coat - ing tape Is fully shrunk: 7. Non-convertible curing def. 8. Convertible cur- ing def. 9. After fully shrink - ing tape, do the following checks: UV or radiation exposure Must be 50% overlap for both Hot and Cold Minimum overlap of 50 mm (2") Anchor the end or the tape Ensure the tape is completely shrunk Do NOT trap a,nr uder the tape! Two parts mixed together just prior to use • Oil • Gas • Water 1. Chlorinated rubber 2. Vinyl 3. Acrylic 4. Bituminous • The tape will shrink down tightly to the pipe surface • The adhesive flows out from the edges of the hot tape No chemical change during cure cycle Some chemical change during cure cycle • Look for adhesive bleed -out • Feel for air pockets • Look for holidays • Repair holidays per the owner's specification NACE C IP 2 STUDY GUIDE ( Master) LATEST U PDATED RATED A. 10.
