Product Features
- One-piece spun and pressed forming creates a smooth dome transition with strong pressure-bearing sealing performance.
- Carbon steel construction provides uniform wall thickness, stable high-pressure resistance, and impact resistance.
- Standard welding bevels allow direct butt welding to pipes for leak-resistant end closure.
- Manufactured to common pipe-fitting standards for accurate dimensions and broad industrial pipeline compatibility.
