Tanya Jawab Umum
The right dimensions depend on:
- Ukuran Pipa Nominal (NPS)
- Pressure Rating (Class 1500)
- Standard Flange Face Type (e.g., Raised Face, Flat Face)
You can refer to the ANSI / ASME B16.5 standard or consult manufacturers’ dimension charts for detailed specifications based on NPS and pressure class.
In addition to ANSI / ASME B16.5, other relevant standards include:
- ASME B31.3 for Process Piping
- ASME BPVC Section VIII for Pressure Vessels
- API 6A for Equipment Used in Oil and Gas Drilling
