The mechanic performance targets such as indentation resistance, impact resistance and tensile strength have reached ISO21809-3 standards. Heat shrink wrap Sleeves provide great corrosion protection, Superior resistance to Cathodic Disbandment and excellent durability against abrasion and chemical attack. The result is effective, good performance of sealing, wide application, easy to operate and preheating temperature,,long term protection against corrosion. | |||
Product Features | High Temperatures 3-Layer (3LPE) Heat-Shrinkable Wrap-around Sleeve is a wraparound sleeve with a separate closure. Cross-linked backing provides superior abrasion, mechanical and chemical attack resistance. High performance adhesive provides excellent resistance to Cathodic Disbondment to ensure long-term corrosion protection Just-in-time customized lengths allow bulk rolls to be field cut top protect any pipe size Open sleeve configuration allows the product to be applied after the pipeline has been welded and cleaned. | |||

Installation Instructions | I. Construction tools: flame spray gun, pressure roller, wire brush, rag, etc. II. Installation steps: 1. Sandblasting and cleaning the joint part: draw the joint installation part at the joint, and remove the water and soil at the joint installation part. 2. Preheating and sanding: preheat the pipe wall at the joint installation position to about 70 ℃ and sanding along the circumference. 3. Apply epoxy primer 4. The HSS shall be used to cover the pipe, the two ends of the pipe to be connected shall be aligned horizontally, and the gap between the two sections shall be kept as small as possible. When the gap is greater than 15mm, the end face of the pipe shall be treated to minimize the gap. 5. Heat evenly along the circumference from the middle, make it shrink completely, and then extend to both ends for heating. When heating, the allowable heating temperature of the heat shrinkable zone shall not exceed 250 ℃, and pay attention to uniform use of fire. After all shrinkage, reheat the uneven surface to make it completely flat. After the whole heating, turn down the flame and reheat again to make the hot melt adhesive overflow fully. 6. During the heating process, the joint is rolled several times with the pressure roller, and the fusion lap joint is mainly rolled to eliminate bubbles. III. Installation quality judgment: 1. The heat shrinkable belt shrinks evenly along the circumference, and the surface is smooth without wrinkles, bubbles, voids, scorching and cracking. 2. The adhesive layer at the edge of the heat shrinkable zone is fully melted and evenly overflowed. IV. Note: 1. When the connected pipe needs to be moved, it should be moved after the joint is cooled to below 50 ℃, and the position with less stress at the joint should be kept as far as possible. 2. The heat shrinkable tape after installation shall be covered to avoid direct sunlight. When the temperature of the joint is too high, the cooling measures (such as watering, etc.) should be taken. | |||
