    DIN86037 flanges are cheaper than copper nickel high neck flanges. DIN86037 flanges are loose-fitting flanges, the outer flange can be rotated \uff0c you can easily install the flange on site.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    The din86037 flange is recommended to be fitted with an insulating liner. Copper nickel inner flange and carbon steel outer flange are two metals. Contact between two different metals will produce potential difference corrosion.<\/p>

    ps: potential difference corrosion is more serious than seawater corrosion.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Are your CuNi10Fe1.6Mn inner flanges forged or cast?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    We can answer unequivocally that our CuNi10Fe1.6Mn inner flange is made from solid bar forging.<\/p>

    We firmly do not use casting to make CuNi10Fe1.6Mn inner flange. Because the casting flange has air holes and is not hard enough. It leads to leakage and serious corrosion during actual use.<\/p>

    Below shows you the photo of metallographic analysis of cast CuNi10Fe1.6Mn inner flange.<\/p>

    You can see the defects in the cast CuNi10Fe1.6Mn flange in the picture below.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
