NACE MR0175 Compliant Flanges and Swage Nipples

At Haihao Group, our commitment to quality and compliance is reflected in every order we deliver. Recently, we completed a custom order for a Singaporean client, supplying high-performance RTJ WN flanges and swage nipples in Nickel Alloy ASTM B564 and B366 UNS N06625, fully compliant with NACE MR0175/ISO 15156 standards.

Our Inconel 625 Grade 1 flanges were designed to match API 6A Type 6BX specifications, with a pressure rating of 10,000 PSI. Each flange underwent strict heat treatment processes and was shipped with standard flange protectors to prevent transit damage.
