Used in construction materials, household products, and agricultural applications. Especially in urban and rural drinking water projects, sewage and wastewater systems, domestic and industrial wastewater pipelines, drainage and storm-water management systems, underground firewater pipelines, infrastructure projects, airports, ports, railways, highway drainage, sports venues, landscape irrigation, geothermal heating/cooling, solar/wind farm water piping, residential/commercial/municipal water dis

Achieves a zero-leakage, permanent joint through a scientifically controlled process creating a homogeneous, monolithic molecular bond. Unlike mechanical seals, it fuses materials into a single entity. Features include molecular diffusion, smart technology with barcode data for automatic process control, real-time monitoring to reject defects, and data logging for traceability. It eliminates the interface where leakage could occur, making it ideal for gas distribution, potable water, and chemica

Step 1: Surface Preparation (scraping to remove oxidized layer). Step 2: Clamping & Alignment (ensures straight position and precise gap). Step 3: Initiation & Heating (voltage applied to coil for uniform melting). Step 4: Melting & Interfusion (molten materials merge with fusion bead filling gaps). Step 5: Controlled Cooling (natural cooling under restraint to prevent stress cracks). Each step ensures a strong, leak-proof molecular bond.

High-Density Polyethylene is a thermoplastic polymer known for high strength-to-density ratio, durability, and impact resistance. We use brand-new, virgin HDPE raw materials from traceable sources (e.g., SHANGHAI JINFEI, ZHEJIANG PETROLEUM & CHEMICAL) to guarantee core performance, environmental stress crack resistance, consistent electrofusion quality, and dimensional stability. This ensures a 50+ year service life and compliance with international certifications.
