ASME B16.5 A694 F65 RF blind plate flanges for low temperature service shipment
Material Advantages: ASTM A694 Gr. F65
ASTM A694 F65 is widely used in high-pressure and low-temperature pipeline applications due to its excellent mechanical properties.
Key Benefits
- High yield strength and tensile performance
- Excellent toughness at sub-zero temperatures
- Suitable for high-pressure transmission pipelines
- Reliable structural stability in critical service
For this order, all RF blind plate flanges for low-temperature service passed the -46°C Charpy impact test, ensuring safe use in cold environments.
Compliance with NACE MR0175
To meet demanding project conditions, the flanges are manufactured in full compliance with NACE MR0175.
This means the RF blind plate flange for low-temperature service is suitable for sour service environments where resistance to sulfide stress cracking is essential.
Such compliance makes these flanges ideal for:
- oil and gas pipelines
- offshore platforms
- petrochemical facilities
- sulfur-containing process lines
Why Raised Face Blind Plate Flanges Matter
The raised face design improves gasket sealing performance and enhances joint reliability under Class 600 pressure conditions.
A high-quality RF blind plate flange for low-temperature service helps:
- safely isolate pipeline sections
- facilitate pressure testing
- provide maintenance access points
- ensure leak-tight shutdowns
This is especially important in critical pipeline systems where safety and uptime are priorities.
