SDR Transition Adaptor
Buttweld Fittings
When joining pipes with different wall thicknesses (SDRs), using the correct transition fitting is essential for a strong and durable weld. Without the right connection, mismatched SDRs can cause notching—a stress concentration that weakens the fusion joint and may result in leaks or even catastrophic failure in service.
SDR Transition Adaptor
Our adaptors are specifically engineered to overcome these challenges. They create a smooth, even connection between pipes of different SDRs. For example, 630 mm SDR9 to 630 mm SDR17. This allows best-practice welding and long-term performance.
Manufactured from high-quality PE100 material and available in a range of PN ratings, each transition adaptor is suitable for both butt fusion and electrofusion welding methods.
Trusted by mining, civil, and industrial professionals across Australia. Our SDR adaptors provide a reliable solution for safe SDR changes, maintaining structural integrity, reducing risk, and delivering confidence in every weld.
