Haihao Group produces ASME B16.48 ASTM A516 Gr.70 spectacle blind flanges with inconel 625 layer for Singapore customers
Haihao Group recently produced ASME B16.48 ASTM A516 Gr.70 spectacle blind flanges with inconel 625 layer for a Singaporean customer. This product was manufactured in three different sizes: 2″, 3″, and 6″. It features a weld overlay of inconel 625, with a thickness of at least 3mm, applied to the surface of the ASTM A516 Gr.70 carbon steel base material. This combination offers excellent corrosion resistance and mechanical strength, making it ideal for high-performance applications in harsh environments.(How to weld overlay or cladding)
Flange with inconel 625 cladding
The ASME B16.48 ASTM A516 Gr.70 spectacle blind flanges with inconel 625 layer are specifically designed for pipeline systems that require a durable solution to isolate sections during maintenance or repair. The ASTM A516 Gr.70 material provides excellent toughness and strength, while the inconel 625 weld overlay ensures outstanding resistance to oxidation, pitting, and crevice corrosion, even in extreme temperatures and aggressive chemical environments.
Haihao Group maintains strict quality control throughout the production process. For this batch of ASME B16.48 ASTM A516 Gr.70 spectacle blind flanges with inconel 625 layer, we provided the customer with several detailed reports to verify the quality of the product:
1.Penetrant Test Report – to ensure the weld integrity and check for any surface cracks or defects in the inconel 625 layer.
2.Ultrasonic Testing (UT) Report – to confirm the absence of internal flaws within the carbon steel base and the weld overlay.
3.PMI (Positive Material Identification) Spectroscopy Report – to verify the chemical composition of the inconel 625 layer and ensure compliance with the required specifications.
4.Weld Overlay Thickness Measurement Report – to confirm that the inconel 625 layer meets the specified minimum thickness of 3mm.
By producing the ASME B16.48 ASTM A516 Gr.70 spectacle blind flanges with inconel 625 layer in various sizes and ensuring each product meets stringent quality standards, Haihao Group demonstrates its commitment to delivering high-performance products for the global market.
