High-Efficiency 90 Degree Electrofusion Flange Pipe Elbow for Water Supply Pipelines

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

They are used in construction materials, household products, and agricultural applications. Specific uses include urban and rural drinking water projects, sewage and wastewater systems, domestic and industrial wastewater pipelines, drainage and storm-water management, underground firewater pipelines, infrastructure projects, airports, ports, railways, highway drainage, sports venues, landscape irrigation, geothermal heating and cooling, solar and wind farm water piping, municipal water distribut

They achieve a zero-leakage, permanent joint through a scientifically controlled process creating a homogeneous, monolithic molecular bond. Unlike mechanical seals, the fitting and pipe become a single entity. The process involves molecular diffusion and interfusion where polymer chains interdiffuse and entangle. Smart technology with barcode data ensures automatic process control, real-time monitoring, and data logging for traceability. This eliminates the interface where leakage could occur, m

Step 1: Surface Preparation removes oxidized layers to ensure clean material for diffusion. Step 2: Clamping & Alignment ensures straight positioning to prevent voids. Step 3: Initiation & Heating applies voltage to melt both surfaces uniformly. Step 4: Melting & Interfusion merges molten materials with internal pressure forcing intermixing and filling gaps with fusion beads. Step 5: Controlled Cooling allows polymer chains to solidify slowly under restraint, preventing stress cracks and maintai

High-Density Polyethylene (HDPE) 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 guarantees core performance (PE100/PE100RC classification), environmental stress crack resistance, consistent electrofusion quality, and dimensional stability. It mitigates risks of catastrophic failure, enables internati
