Qingdao Tianzhida High-Tech Industrial Development Co., Ltd. is a professional manufacturer specializing in the production of large-diameter plastic drainage pipes, prefabricated directly buried heating pipes with plastic-clad steel, chemical containers, and other joint rehabilitation products. Main products include: electrofusion bands, electrofusion sleeves, specialized electrofusion bands for steel strip reinforced polyethylene spiral corrugated pipes, electrofusion bands for HDPE hollow-wall winding pipes, handheld plastic extrusion welding guns, electrofusion welding machines, heat-shrinkable bands, heat-shrinkable sleeves, plastic welding rods, stainless steel clamps, stainless steel buckles, EVA hot melt adhesives, and more.

The electrofusion sleeves for polyurethane insulated pipes produced by Qingdao Tianzhida High-Tech Industrial Development Co., Ltd. are manufactured using specialized PE sheets. Through a special thermal fusion integration process, a specific nickel-chromium alloy mesh is thermally fused and formed in one step. Due to the use of high-quality raw materials for the PE sheets, combined with a certain proportion of EVA hot melt adhesive, and produced via co-extrusion equipment through a composite die for homogeneous melting, followed by corona treatment, a small amount of gelled material can overflow during welding and melting. Coupled with the fine texture and uniform arrangement of the nickel-chromium alloy mesh, which generates high heat per unit time, it achieves excellent fusion with PE pipelines, ensuring significant sealing effects and superior welding performance.

Application: Primarily used for connecting joints of anti-corrosion insulated pipes and heating pipelines.

Characteristics: Excellent sealing performance, corrosion resistance, long service life, and ease of use.
