High-performance ASME B16.48 ASTM A516 Gr.70 spectacle blind flanges with inconel 625 cladding for Singaporean client
Haihao Group, a leading provider of advanced pipeline solutions, recently completed the production of ASME B16.48 ASTM A516 Gr.70 spectacle blind flanges with a 3mm inconel 625 weld overlay for a key customer in Singapore. These flanges were fabricated in three different sizes—2″, 3″, and 6″—to meet specific project needs, delivering exceptional performance in highly corrosive and high-temperature environments.
Material Overview and Technical Benefits
The base material, ASTM A516 Gr.70 carbon steel, is widely recognized for its superior toughness, ductility, and weldability, making it a reliable choice for structural components subjected to high-pressure environments. By integrating Inconel 625 cladding, a nickel-chromium alloy known for its resistance to oxidation, pitting, and crevice corrosion, the flanges are specifically designed to offer excellent mechanical strength and corrosion protection in the harshest operating conditions, including environments with aggressive chemicals and fluctuating temperatures.
The Inconel 625 overlay was applied with precision using advanced weld overlay or cladding techniques to achieve a minimum thickness of 3mm. This process ensures that the carbon steel core retains its structural integrity while the Inconel 625 layer shields the flange from corrosion, prolonging its service life in demanding applications.

Cladding and Weld Overlay Process
Weld overlay, also known as cladding, involves the application of a corrosion-resistant alloy—Inconel 625 in this case—over a carbon steel substrate. The overlay is deposited via a controlled welding process, which fuses the alloy onto the base material to create a metallurgically bonded layer. This method is ideal for enhancing the performance of flanges used in corrosive environments, as it combines the structural advantages of carbon steel with the exceptional corrosion resistance of Inconel 625.
At Haihao Group, this weld overlay process is carried out with strict adherence to industry standards to ensure the uniformity and durability of the Inconel layer, providing customers with a product that performs reliably even under the most challenging conditions.

Quality Assurance and Testing
As part of our commitment to quality, every batch of ASME B16.48 ASTM A516 Gr.70 spectacle blind flanges with Inconel 625 cladding undergoes a rigorous quality control process. For this project, the following tests and inspections were conducted:
- Penetrant Testing: This non-destructive testing method was used to check for any surface cracks or defects in the Inconel 625 weld overlay. The test ensures the structural integrity of the weld and helps identify any surface imperfections that could compromise performance.
- Ultrasonic Testing (UT): To verify the internal soundness of the carbon steel base material and the cladding, ultrasonic waves were used to detect any subsurface flaws, such as voids or inclusions. This ensures the flange’s core strength remains uncompromised and the weld overlay is properly bonded.
- Positive Material Identification (PMI): A detailed PMI spectroscopy report was provided to confirm that the Inconel 625 cladding meets the exact chemical composition required for the application. This ensures compliance with international material standards, guaranteeing the alloy’s resistance to corrosion in extreme conditions.
- Weld Overlay Thickness Measurement: Using precise measuring instruments, the weld overlay thickness was confirmed to be at least 3mm, meeting the customer’s stringent specifications. Proper overlay thickness is essential to ensure long-term durability and performance, particularly in corrosive environments.
Tailored Solutions for Challenging Environments
The spectacle blind flanges are designed to isolate sections of a pipeline, allowing for maintenance or repair while ensuring complete system integrity. The combination of ASTM A516 Gr.70 and Inconel 625 makes these flanges ideal for industries such as oil and gas, petrochemicals, and power generation, where equipment is frequently exposed to corrosive elements and high temperatures.
Haihao Group’s ability to customize flange production in various sizes and materials demonstrates our flexibility in meeting the unique demands of each customer. For this particular project, the different size options provided the client with versatility in installation, ensuring compatibility across multiple sections of the pipeline system.
