Manufacturer, Supplier & Exporter of Alloy Steel Pipe Nipple

Alloy steel pipe nipples are short lengths of piping or fittings with male threads at each end (or one end) that allow connection of two female‐fitted pipe segments or fittings. In the case of alloy steel, the material is selected for higher strength, temperature endurance and sometimes corrosion or creep resistance beyond standard carbon steel. Riddhi Siddhi Impex lists alloy steel pipe nipples under their pipe‑fittings‑nipple product range: “Alloy steel: ASTM / ASME A234 WP 1, WP 5, WP 9, WP 11, WP 12, WP 22, WP 91” among other material grades...
