HDPE Coupler is a straight-through connector for connecting two sections of HDPE pipes, suitable for hot-melt or electric-melt connection. Made of high-density polyethylene (PE100 or PE100RC), this product has excellent pressure resistance, corrosion resistance and sealing, and is an ideal choice for pipe connections in municipal, agricultural, industrial, mining and other fields.
Product Features
(1) Excellent material properties
Strong corrosion resistance: HDPE Coupler can resist the erosion of acids, alkalis, salts and organic solvents, and is suitable for harsh environments such as chemical industry and sewage treatment.
High toughness & impact resistance: It maintains good flexibility even in low temperature environments and is not easy to crack.
Lightweight & easy to install: Lightweight, easy to transport and construct, and reduces labor costs.
Long life: Excellent anti-aging performance, with a service life of more than 50 years.
(2) Reliable connection method
Butt fusion coupler: The butt is heated by a hot-melt welding machine to integrate the joint with the pipe without the risk of leakage.
Main application areas
Municipal water supply and drainage: urban water supply and sewage network connection.
Gas transmission: high pressure resistance, leakage prevention, in line with gas pipeline safety standards.
Industrial pipelines: fluid transportation systems such as chemical, electric power, mining, etc.
Agricultural irrigation: good weather resistance, suitable for underground drip irrigation systems.
Production process and quality control
Raw materials: high-quality PE100 or PE80 grade HDPE raw materials are used to ensure strength and chemical resistance.
Manufacturing process: injection molding, some high-pressure pipe fittings use steel wire reinforced structure.
Testing standards: in line with international/national standards such as ISO 4427, GB/T 13663, etc., to ensure sealing and pressure resistance.
Market advantages
1. High sealing: no leakage after welding, better than traditional flange connection.
2. Convenient construction: reduce labor and machinery costs, improve engineering efficiency.
3. Economic and durable: low maintenance cost, high cost performance for long-term use.

HDPE Electrofusion Coupling is a type of HDPE pipe fitting that uses electric fusion technology to connect. It is widely used in gas transportation, municipal water supply and drainage, industrial fluid transportation and other fields. It achieves high-strength, leak-free pipe connection through heating and fusion with built-in electric heating wire, and is a key component of modern HDPE pipe systems.
HDPE Electrofusion Coupling Features
(1) High sealing & high-strength connection
Built-in resistance wire: Evenly heated after power is turned on, the pipe and the fitting are fused to form an integrated structure, eliminating the risk of leakage.
High pressure resistance: Suitable for PN10, PN12.5, PN16 and other pressure systems. Some products can meet higher pressure requirements.
(2) Corrosion resistance & long life
HDPE material: Acid and alkali resistant, chemical resistant, suitable for harsh environments such as sewage treatment and chemical pipelines.
Service life of more than 50 years: Excellent anti-aging performance, reducing maintenance costs.
(3) Convenient construction & strong adaptability
Quick installation: Only HDPE ElectroFusion Welding Machine is required to complete the connection, without complex equipment, improving construction efficiency.
Various specifications: suitable for pipe diameters from DN180 to DN1200mm, compatible with HDPE pipes such as PE80 and PE100
Main application areas
1. Gas pipeline: high sealing meets gas safety standards to prevent gas leakage.
2. Municipal water supply/drainage: pressure-resistant and corrosion-resistant, suitable for urban pipeline construction.
3. Industrial fluid transportation: corrosion-resistant pipeline systems in chemical, power and other industries.
Production process and quality control
Precision injection molding: ensure dimensional accuracy and structural strength.
Evenly arranged heating wires: optimize welding effect and avoid local overheating or cold welding.
Strict testing: each batch of products is pressure tested and sealed to ensure reliability.
