Weldo flange or Nipo Flanges is the combination of Welded Neck Flange and Weldolet. Both these components are manufactured in one piece and are not welded. These flanges are primarily in branch connects which are designed more minutely for excellent smooth follow of liquid or gas in petro or chemical industry. You can also request a customised requirement for you type of industry. The standards includes for Stainless Steel Weldo / Nipo Flanges are ASME SA 182 F, 304, 304L, 304H, 309H, 310H, 316, 316H, 316L, 316 LN, 317, 317L, 321, 321H, 347, 347 H. For Carbon Steel Weldo / Nipo Flanges are as follows ASTM / ASME A 105, ASTM / ASME A 350 LF 2 and for Alloy Steel Weld / Nipo Flange are ASTM / ASME A 182 GR F 5, F 9, F 11, F 12, F 22, F 91. Alloy Steel Weldo/ Nipo Flanges are as ASTM / ASME A 182 GR F 5, F 9, F 11, F 12, F 22, F 91. Again for different types of industry there are types of other requirement which are customised according to the size and materials along with standards and dimensions or likewise with their grades
