Low-Temperature Resistant 90 Degree Electrofusion Flange Pipe Elbow for Underfloor Heating Systems

Factory Direct Pricing, Large Stock, Quality. Manufacturer offers fittings from 20mm to 1400mm, rated for PN10 to PN25. Custom branding and products are backed by three plants. We maintain large inventory, offer competitive pricing with strict in-house quality control, and rapidly source and consolidate all related piping products.

Commonly used in construction materials, household products, and agricultural applications. Applications include urban and rural drinking water projects, sewage and wastewater systems, drainage and storm-water management, underground firewater pipelines, infrastructure projects, airports, ports, railways, highway drainage, sports venues, landscape irrigation, geothermal heating/cooling, solar/wind farm water piping, municipal water distribution, agricultural irrigation, gas distribution networks

Achieves a zero-leakage, permanent joint through a molecular bond between fitting and pipe. The process involves thermal fusion where polymer chains interdiffuse and recrystallize into a single mass. Smart technology uses barcodes to store welding parameters, ensuring automatic process control, real-time monitoring, and data logging for traceability. Unlike mechanical fittings, it has no seal aging or vibration sensitivity, offering lifetime performance equal to the pipe (50+ years).

Step 1: Surface Preparation to remove oxidized layers. Step 2: Clamping & Alignment to eliminate stress. Step 3: Initiation & Heating to create a uniform melt zone. Step 4: Melting & Interfusion where molten materials merge and fusion beads fill gaps. Step 5: Controlled Cooling to prevent stress cracks. This ensures a stress-free joint that maintains integrity under cyclic 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 (e.g., SHANGHAI JINFEI, ZHEJIANG PETROLEUM). This guarantees Core Performance (PE100/PE100RC classification), Environmental Stress Crack Resistance (ESCR), Consistent Electrofusion Quality, and Dimensional Stability. It ensures a 50+ year service life, passes international certifications (CE, ISO), and
