Haihao Group Ships ASTM A105/A105N Forged Flanges to Côte d’Ivoire
Haihao Group has successfully delivered a new batch of forged carbon steel flanges to a valued customer in Côte d’Ivoire. The shipment includes weld neck (WN) flanges, socket weld (SW) flanges, and blind flanges, all manufactured in accordance with ASTM A105 and ASTM A105N standards to ensure outstanding strength and sealing performance for industrial pipeline systems.
These flanges are designed for high-pressure and high-temperature applications, commonly used in oil and gas facilities, petrochemical plants, and power generation projects. Each product underwent strict dimensional inspection and material verification before shipment to guarantee compliance with ASME B16.5 and client-specific requirements.

| FLANGE WN RF 600# 2″ SCH.160 ASTM A105N | Weld neck flange | 2″ | 600#, SCH.160 | RF | ASTM A105N |
| FLANGE WN RF 900# 1½” SCH.160 ASTM A105N | Weld neck flange | 1½” | 900#, SCH.160 | RF | ASTM A105N |
| BLIND FLANGE RF (TAPPED HOLE ¾”) 2″ 600# ASTM A105N | Blind flange | 2″ | 600# | RF | ASTM A105N |
Each flange is hot-forged and precision-machined to deliver optimal performance in sealing and pressure containment. The raised-face (RF) design ensures a secure and tight joint when paired with suitable gaskets, minimizing the risk of leakage under demanding operating conditions.
Performance You Can Trust
The use of ASTM A105 and A105N carbon steel provides excellent mechanical strength, impact resistance, and weldability. The “N” designation indicates normalized heat treatment, which refines grain structure and enhances toughness—making it ideal for high-pressure piping systems exposed to dynamic loads and temperature variations.
Key advantages of Haihao forged flanges:
- High dimensional accuracy and smooth sealing surfaces
- Reliable performance under pressure and temperature fluctuations
- Conformance to ASTM, ASME, and EN standards
- Optional heat treatment and NACE MR0175 compliance for critical services
