HDPE Electrofusion Stub End

HDPE Electrofusion Stub End Engineering Benefits:

✓ Dual Connection Technology – Integrates seamless electrofusion welding on the pipe side with standardized flange bolting on the equipment side, enabling easy demounting for valve replacement or system maintenance

✓ Superior Chemical Resistance – PE100 material provides exceptional corrosion resistance against acids, alkalis, and electrolytic environments, eliminating the need for cathodic protection

✓ Leak-Proof Integrity – Precision-machined flange face with serrated finish ensures perfect gasket seating and zero leakage under rated pressure conditions

✓ Installation Efficiency – Pre-fabricated design reduces field welding time by 60% compared to traditional fabricated stub ends; compatible with all ISO standard flange drilling patterns (EN 1092-1, ANSI B16.5, AS 2129)

✓ Long Service Life – 50+ years design life with excellent stress cracking resistance (ESCR) and UV stabilization for outdoor applications
