Product Description

HDPE Electrofusion Tapping Saddle is specifically designed to tap into existing HDPE pipelines. These fittings provide a reliable solution for bypass, purging, and off-takes in various piping systems.

💡

Technical Overview: It features implanted metal coils around the inner surface. The branch outlet is a long spigot type, requiring a coupler for connection. Each tapping tee is assembled with an internal metal cutter. Once welding is complete, installers use a specialized tool to screw down the cutter, tapping the hole, and then sealing the access to allow flow into the branch.

Manufactured from 100% PE100 virgin material, these saddles are available in diameters from 63×25mm to 315×90mm, conforming to international standards including ISO4427-3, EN12201-3, AS/NZS 4129, and EN1555.

Key Advantages

Simple Installation: Lightweight equipment allows for easy joining in confined spaces where butt fusion is not practicable.
Cost Effective: Reduces labor costs due to the simplified welding process and faster operation.
Superior Reliability: Consistent welding creates joints that are often stronger than the pipe itself.
Maintenance Friendly: Supports secondary welding if leaks occur and allows for quick pipeline repairs.
High Resistance: Excellent corrosion resistance and hygiene for water and gas distribution.

Quality Control & Materials

🛡️

We utilize top-tier PE100 materials from globally recognized suppliers such as Borealis (HE3490-LS), Sabic (P6006), and Sinopec (YGH041T). All products are manufactured in ISO9001 certified facilities.

Frequently Asked Questions

1. What is the electrofusion welding process?

It involves pipe preparation (cleaning/scraping), marking, applying electrical current through the fitting's internal coils, and a strictly timed cooling period to ensure a permanent bond.

2. Is scraping necessary before installation?

Yes. It is critical to scrape the oxidation layer (approx. 0.3mm depth) from the pipe surface to ensure proper molecular fusion during the heating cycle.

3. Can these fittings be used for PPR pipes?

No. HDPE electrofusion fittings are designed specifically for HDPE pipelines and are not compatible with PPR materials.

4. Why do some electrofusion joints fail?

The most common reasons are poor surface preparation (lack of scraping), contamination by dirt or grease during handling, or misalignment of the pipe within the fitting.

5. Are the fittings compatible with different PE grades?

Yes, PE100 electrofusion fittings can generally be welded to PE80 pipes, though using matching grades is recommended for the best results.

6. How are welding parameters managed?

Each fitting is equipped with a barcode. On-site workers can scan this with the electrofusion machine to automatically input the correct welding voltage and time.
