Product Description

Product Description

HDPE Electrofusion (EF) 45 Degree elbow
  Zhejiang Fengfeng Pipe's HDPE Electrofusion 45 Degree Elbow is a high-performance polyethylene pipe fitting designed for safe and reliable directional changes in HDPE pipeline systems. Manufactured from 100% virgin PE100 raw material, this electrofusion elbow offers excellent durability, corrosion resistance, chemical resistance, and long-term pressure performance.
The fitting is equipped with embedded copper heating wires, allowing efficient electrofusion welding with HDPE pipes. During installation, the welding process creates a strong molecular connection between the fitting and pipe, providing a leak-proof joint with excellent mechanical strength. The precise socket design ensures easy alignment and stable installation.
This 45-degree HDPE elbow is widely used in municipal water supply, drinking water pipelines, irrigation systems, industrial water transportation, mining, drainage systems, and underground piping projects. It is suitable for applications requiring high reliability, low maintenance, and a long service life.
Available in various sizes and pressure ratings, including SDR11 PN16 and SDR17 PN10, our HDPE electrofusion fittings comply with international standards such as ISO 4427 and EN 12201. OEM customization, private labeling, and customized packaging are available to meet different market requirements.

Application

Municipal Water Supply Systems: Used for drinking water pipelines, urban water distribution networks, and buried water transmission projects.
Agricultural Irrigation: Suitable for farmland irrigation, greenhouse irrigation, sprinkler systems, and water delivery pipelines.

Step 1: Pipe Cutting and Surface Preparation

Step 2: Pipe Insertion and Alignment

Before welding, cut the HDPE pipe end squarely using a suitable pipe cutter or cutting tool. Clean the pipe surface and remove any dirt, dust, oil, or moisture. Use a scraping tool to remove the oxidized layer from the pipe surface to ensure a clean PE material layer is exposed. Proper preparation is essential for achieving a strong molecular fusion connection.

Insert the prepared HDPE pipe ends into the electrofusion fitting socket according to the marked insertion depth. Ensure the pipe and fitting are properly aligned without excessive movement or gaps. Secure the pipe using clamps or alignment tools to prevent displacement during the welding process. Correct positioning helps ensure uniform heat distribution inside the fitting.

Step 3: Electrofusion Welding

Step 4: Cooling and Quality Inspection

Connect the electrofusion welding machine terminals to the copper pins on the fitting. Scan the barcode or manually input the welding parameters according to the fitting specifications. The welding machine supplies controlled electrical energy to heat the embedded copper wire, melting the surrounding PE material. The molten polyethylene from the fitting and pipe surface combines to form a strong, permanent molecular bond.

After completing the welding cycle, keep the pipe and fitting fixed during the recommended cooling time. Do not apply pressure or move the joint before the cooling process is finished. Once cooled, inspect the welding indicators, fitting position, and overall appearance to confirm a proper connection. A correctly completed electrofusion joint provides excellent sealing performance, pressure resistance, and long service life.

FAQ

What material is used for your HDPE Electrofusion Fittings?

Our HDPE Electrofusion Fittings are manufactured from 100% virgin PE100 polyethylene material, which provides excellent strength, impact resistance, corrosion resistance, and long-term durability. The fittings are suitable for drinking water, irrigation, industrial pipelines, and underground PE piping systems. High-quality raw materials ensure stable welding performance and reliable service life.

What standards and certifications do your electrofusion fittings comply with?

Our electrofusion fittings are designed and produced according to international HDPE pipe fitting standards, including EN 12201-3 and ISO 4427-3 requirements. We can provide quality documents, inspection reports, and certificates according to customer project requirements. OEM production and customized specifications are also available for different markets.

How does the electrofusion welding process ensure a strong connection?

The fittings contain embedded copper heating wires that generate controlled heat during the electrofusion process. The heat melts the inner surface of the fitting and the pipe surface, creating a permanent molecular bond after cooling. This results in a leak-free connection with high pressure resistance and excellent mechanical strength.

What sizes and pressure ratings are available?

We supply a wide range of HDPE Electrofusion Fittings, including couplers, elbows, tees, reducers, and saddles. Common sizes range from 20mm to 1400mm, with pressure ratings such as SDR11 PN16, SDR17 PN10, and SDR7.4 PN25. Customized sizes, colors, and packaging are available upon request.

Why should we choose your factory for HDPE Electrofusion Fittings?
