Haihao Group Ships Custom SA694 F65 Blind Flanges to Indonesia
Haihao Group has successfully shipped custom SA694 F65 blind flange units tailored to client drawings for an Indonesian industrial pipeline project. Unlike standard stock flanges, this batch features a full flat face design with no bolt holes, manufactured strictly per custom dimensional and mechanical performance requirements for low-temperature piping service.
Custom SA694 F65 flat face blind flange without bolt holes, heat treated with -46°C low temperature impact resistance, shipped to Indonesia by Haihao Group
Product Technical Specification
| Product Type | Outer Diameter | Thickness | Material | Structural Feature | Technical Requirement |
| FF Blind Flange | 215.9mm | 44.45mm | ASTM SA694 F65 | Flat Face, No Bolt Holes | Heat treated, -46°C low temperature impact resistance |
| FF Blind Flange | 292.1mm | 50.8mm | ASTM SA694 F65 | Flat Face, No Bolt Holes | Heat treated, -46°C low temperature impact resistance |
The custom SA694 F65 blind flange batch includes two non-standard specifications. The first unit boasts an outer diameter of 215.9mm and a thickness of 44.45mm, while the second measures 292.1mm in outer diameter with 50.8mm thickness. Both flat face blind flanges adopt a bolt-hole-free structure, offering integrated sealing performance for pipeline isolation and shutdown applications.
To meet the project’s harsh low-temperature operating conditions, every SA694 F65 blind flange undergoes professional heat treatment to stabilize internal microstructure and mechanical properties. The core technical highlight lies in qualified -46°C low-temperature impact resistance, ensuring the flanges maintain stable toughness and structural integrity in extreme cold working environments common in Indonesian industrial facilities.
As a high-yield carbon steel flange grade, the SA694 F65 blind flange delivers excellent pressure-bearing capacity and mechanical stability. Our quality team conducted full dimensional calibration and performance testing for each custom flange, strictly verifying heat treatment effects and low-temperature impact indicators to fully comply with client drawing specifications and industrial safety standards.
