HDPE Seamless Electro Fusion Welding Belt / Tape for Preinsulation Pipe Joint

HDPE Seamless Electro Fusion Welding Belt / Tape for Preinsulation Pipe Joint

Huashida HDPE Electro Fusion Sleeves is a pipe interface welding material: high-quality HDPE sheet is cut into sheets that meet the required length, width, and thickness according to actual needs, and then combined with special electric heating wire mesh through special heat sealing equipment. It solves the problems of the traditional pipeline connection is not tight, water seepage and air leakage.

Seamless hot melt sleeve process:

1.The working pipe is heated (expands)
2. The outer protective pipe is heated (tightened)
3. Expand internally and contract externally, with a tight combination

1.District Thermal Heating System Construction: Ensuring secure and leak-proof connections in extensive heating networks.
2.Pre-Insulated & Oil Pipe Field Joint Welding: Providing reliable welding for on-site connections of pre-insulated and oil pipelines.
3.Hollow Wall & Structure Pipe Joint Fitting: Ideal for joining sections of hollow wall spiral pipes and structured wall pipes. 
4.Steel Reinforced Spiral Pipe Joint Fitting: Ensuring strong and durable connections for steel reinforced spiral pipes.

1.High connection strength
2.Good sealing effect
3.It has a high airtight pressure resistance performance
4.Corrosion-resistant and aging-resistant
5.The bonding is firm and reliable.
6.Long service life
7.Reduce construction costs and maintenance expenses

Seamless hot melt sleeve operation process

1.Surface treatment with No. 50 sandpaper
2. Overlap 75mm for positioning
3. Apply a 5mm thick adhesive sheet along the positioning edges at both ends
4. Restore the heat shrinkable sleeve to the designated position
5. Bake over a flame for 15 to 20 minutes
6. Both ends of the port are sealed with 100mm heat shrink tape
7. Conduct a sealed test at 0.2Mpa for 3 minutes without leakage
