Large inventory, competitive pricing with strict in-house quality control. We rapidly source and consolidate all related piping products.

Used in construction materials, household products, and agricultural applications. Key sectors include urban and rural drinking water projects, sewage and wastewater systems, drainage and storm-water management, underground firewater pipelines, airports, ports, railways, highway drainage, sports venues, landscape irrigation, geothermal systems, solar and wind farm water piping, municipal water distribution, agricultural irrigation, gas distribution networks, chemical processing plants, mining sl

Achieves zero-leakage, permanent joints through a molecular bond that fuses fitting and pipe into a single entity. Core principle involves thermal fusion where polymer chains interdiffuse and recrystallize. Smart technology uses barcode data for automatic process control, real-time monitoring, and data logging to eliminate human error. Unlike mechanical fittings, it has no seal aging or loosening issues, offering lifetime performance equal to the pipe.

Step 1: Surface Preparation scrapes oxidized layers to ensure clean material for diffusion. Step 2: Clamping aligns pipe and fitting to prevent voids. Step 3: Initiation heats the coil to melt both surfaces uniformly. Step 4: Melting merges materials with fusion beads filling gaps. Step 5: Controlled cooling solidifies the joint without stress cracks, ensuring integrity under pressure and temperature changes.

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 like SHANGHAI JINFEI PETROCHEMICAL and ZHEJIANG PETROLEUM & CHEMICAL. This ensures Long-Term Hydrostatic Strength (LTHS), Environmental Stress Crack Resistance (ESCR), consistent electrofusion quality, and dimensional stability.
