Key Features of HDPE Butt Fusion Riser Inspection Opening for Siphonic Drainage
- Provides direct access to vertical stacks for inspection and rodding.
- Tight-sealing access cover prevents leakage and odor escape.
- Butt fusion joints on both ends form a homogeneous monolithic structure.
- High-strength body withstands drainage surge and water hammer.
- Corrosion-resistant HDPE ensures long service life inside buildings.
Manufacturing Process of HDPE Butt Fusion Riser Inspection Opening for Siphonic Drainage
Each inspection opening is injection molded from HDPE PE100 resin with precision tooling. The branch access port is formed via multi-slider tooling, and the sealing cover seat is precision-machined for a consistent, leak-tight fit. The butt fusion ends are machined to precise diameter and flatness for reliable fusion joining.
Critical Process Parameters of HDPE Butt Fusion Riser Inspection Opening for Siphonic Drainage
- Access port and cover seat dimensional accuracy.
