Installation Guidelines
Best practices for optimal performance and longevity
Do's
- ✓Use EPC 40 for normal duty above ground or concrete-encased applications
- ✓Select EPC 80 for heavy-duty applications requiring higher wall thickness
- ✓Ensure EB type ducts are encased in concrete during installation
- ✓Utilize DB type ducts for direct burial without the need for concrete encasement
Don'ts
- ✗Do not use EB series ducts for direct burial applications without concrete encasement
- ✗Avoid using Class-O (non-pressure) pipes for applications requiring specified working pressures
- ✗Do not exceed the specified working pressure ratings for PN series pipes at 20°C
- ✗Avoid mismatched accessories; use standard duct sockets, end caps, and bellmouths for secure connections
