Haihao Group Ships ASME B16.5 Blind Flange and ASTM A182 F11 Socket Weld Flange to Singapore
Haihao Group has completed another export order of forged flanges for a valued customer in Singapore. This shipment includes an ASME B16.5 blind flange manufactured from ASTM A105 carbon steel and a socket weld flange produced from ASTM A182 F11 Class 2 alloy steel. Both products were manufactured in accordance with ASME B16.5 requirements and carefully inspected before shipment.
Although compact in size, these forged flanges are intended for high-pressure piping systems where reliable sealing, precise machining, and long-term service performance are essential. The successful delivery once again demonstrates Haihao Group’s ability to provide customized flange solutions for industrial projects worldwide.

ASME B16.5 ASTM A105 RF blind flange and ASTM A182 F11 Class 2 socket weld flange
Designed for Reliable Industrial Service
The two flange types in this shipment serve different purposes within process piping systems.
The ASTM A105 blind flange is used to terminate pipelines or isolate sections of a piping system during maintenance and pressure testing. Its forged construction provides dependable sealing performance under medium- and high-pressure conditions.
The ASTM A182 F11 socket weld flange is commonly selected for small-bore, high-temperature piping where alloy steel offers improved strength and creep resistance. Socket weld connections also help achieve strong, leak-resistant joints in compact piping layouts.
By combining carbon steel and alloy steel materials, the customer can optimize both cost and performance according to different service conditions.
Quality Manufacturing from Raw Material to Final Inspection
Each ASME B16.5 flange undergoes a controlled manufacturing process supported by Haihao Group’s quality management system.
Inspection procedures include:
- Raw material verification
- Forging quality inspection
- CNC machining inspection
- Dimensional measurement
- Facing and sealing surface inspection
- Visual examination
- Material traceability verification
These inspection steps ensure that every ASME B16.5 flange fully complies with customer specifications before export.
Advantages of Forged Flanges
Forged flanges remain the preferred choice for critical industrial piping because of their excellent mechanical properties and structural integrity.
Key advantages include:
- High pressure resistance
- Excellent dimensional accuracy
- Reliable sealing performance
- Strong mechanical strength
- Long service life
- Easy installation and maintenance
Whether manufactured from ASTM A105 carbon steel or ASTM A182 F11 alloy steel, forged flanges provide dependable performance for refineries, petrochemical plants, power stations, offshore facilities, and process industries.
