Huashida seamless hot melt sleeve integrates the dual advantages of electric heat melt sleeve and heat shrink sleeve, solving the pain points of traditional joint materials such as limited thickness (only 3mm), reliance on power supply and high welding failure rate. Its thickness ranges from 3 to 18mm and is suitable for complex working conditions. The construction only requires a flame gun for baking and does not need an external power supply, avoiding the risk of seal failure caused by unstable voltage and ensuring a 100% pass of the airtight test. The polyethylene base material innovatively adopts the biaxially oriented process, with its strength increased by more than 20% compared to the pipe base material. It also supports the superimposition of electric heating wire mesh or heat shrink tape for auxiliary reinforcement, achieving a dual sealing guarantee of "heat shrinkage + electric fusion".
Through unremitting efforts and insistence on independent research and development, Huashida has obtained a utility model patent certificate. Huashida seamless electrofusion sleeves have been widely used in major projects in over 30 countries, and export orders have also been continuously increasing. Its reliability has been certified by authoritative institutions such as the Pipeline Bureau of China National Petroleum Corporation, making it a benchmark for "high cost performance" in the industry.
