Engineered for seamless integration into industrial and municipal pipelines, the Series 573 Electrofusion Branch Saddle with Flange combines advanced hydraulic compression technology with ANSI B16.5-compliant flanges. Designed for sizes 1.25” to 18”, this fitting ensures a secure, leak-proof connection between HDPE pipes and flanged systems, even under extreme pressure fluctuations. Ideal for water distribution, fire protection, and chemical processing, it features a multi-level barbed design that strengthens under stress and meets ASTM, NSF, FM, and AWWA standards.
Key Features & Benefits
- ANSI B16.5 Flange Compliance: Available in 150#, 300#, and 600# pressure ratings for versatile system compatibility.
- Pressure-Activated Seal: Multi-level barbs expand under internal pressure, ensuring zero leaks during thermal shifts or static conditions.
- 50-Year Durability: Built with a 2:1 safety factor at 73.4°F, certified to ASTM 1598/1599 and ARRA requirements.
- Corrosion-Resistant Materials: Epoxy-coated carbon steel (IF 194T), 304/316 stainless steel, or ERW pipe options for harsh environments.
Technical Specifications
- Sizes: 1.25”–18” (ANSI B16.5 flanges).
- HDPE Pipe: ASTM D3350 (PE3408/PE4710), F714, D3035. Tensile strength: 3,200–3,500 psi; ESCR ≥5,000 hours (zero failures).
- Melt Index: ≤0.15 g/10 min (ASTM D1238).
Installation Guidelines
- Follow electrofusion manufacturer’s procedures for saddle installation on main pipes.
- Use tapered coupling to cold-press HDPE into multi-level barbs—no heat required.
- Pressure-test joints before backfilling; compact soil to prevent ground shifts.
Material & Compliance
- Flanged Fittings: Carbon Steel (A53/A106, epoxy-coated), 304/316 Stainless Steel (ASTM A249/A269), or ERW pipe (ASTM SA-312).
