The PE Electrofusion 90° Elbow (PN20) is made from High-Density Polyethylene (HDPE) and features integrated precision resistance wires. It uses electrofusion welding to create a molecular-level bond between the fitting and the pipe, ensuring a permanent, sealed connection. This product is specifically designed for pressure pipeline systems and is particularly suitable for applications that require strict sealing integrity, such as water supply, gas distribution, and chemical industries. The Electrofusion 90° Elbow PN20 offers reliable performance under medium-high pressure conditions.

FAQ

Q: How are the welding parameters for the Electrofusion 90° Elbow set?

A: The welding parameters are detailed on the product label or manual. The welder must be set strictly according to the specified voltage, time, etc.; arbitrary adjustments are not permitted. Typical parameter example: For the L110 elbow, the welding time is approximately 270 seconds, with a cooling time of no less than 10 minutes.

Q: How to inspect the welding quality?

A: Quality can be inspected through the following four steps:
1. Visual Inspection: Check that the joint is even and free of cracks.
2. Dimensional Measurement: Ensure the outer diameter error is ≤ 0.5mm.
3. Seal Test: Perform a pressure hold test (30 minutes) with a pressure drop ≤ 0.05MPa.
4. Strength Test: Conduct sample tensile tests.

Q: Is this elbow suitable for chemical media?

A: The HDPE material offers good resistance to acids and alkalis, making it suitable for conveying most chemical media. It is advisable to confirm media compatibility before use.

Q: Do you support custom non-standard sizes?

A: Yes, we support custom manufacturing. Parameters like outer diameter and wall thickness can be adjusted according to customer requirements. Please contact customer service to confirm the Minimum Order Quantity (MOQ).

Q: How to troubleshoot leakage after welding?

A: Please contact our after-sales team promptly and provide a video or photos of the welded area. We will guide you through checking the resistance value with a multimeter or arrange for technical personnel to provide on-site support. Proper installation is crucial for the Electrofusion 90° Elbow PN20.
