This new type of seamless hot-melt sleeve is a novel hot-melt pipe fitting independently developed. Its base material is polyethylene, processed through biaxial stretching. The thickness of the fitting's base material is the same as the pipe substrate, but its strength is increased by more than 20%. During construction, only a flame gun is used for heating; after shrinking, the fitting tightly connects to the pipe, fully meeting the standards for airtightness testing. If the pipe deforms at the port during foaming or transportation, the hot-melt sleeve may not pass the airtightness test 100% after welding. In this case, 100mm wide heat-shrinkable tape can be used on both sides of the seamless hot-melt sleeve for auxiliary reinforcement, ensuring the joint passes the airtightness test 100%. Alternatively, heating elements can be placed on the base material for secondary heating to complete the hot-melt process, thus ensuring the airtightness test passes.
