Scope And Manufacturing

ASTM B366 covers nickel alloy pipe fittings. These pipe fittings are grades of (UNS N04400, UNS N10276, UNS N06022, UNS N10665, UNS N08020, UNS N02200 , UNS N02201) nickel and nickel alloys. Seamless pipe fittings are manufactured through hot rolled round bar billet of steel alloy. The billets are cut into suitable length depending on the required length of the finished fitting. The billets are heated in a furnace at a temperature of 1200 degree celsius to 1300 degree celsius. Then the seamless fitting is formed by drawing a solid billet over a piercer to create the hollow shell (mother blanks). These hollows are crimped at one end in hot condition and then, they are air cooled. The fittings are then surface treated (pickled, phosphate coated and lubricated) to facilitate the next process of drawing. Depending on the finished sizes required, the fittings are subjected to single, double or triple drawing. After every draw the fittings are annealed at a temperature of 750 degrees. The fittings are then straightened and cleaned if necessary and before being cut to the exact size required. The finished fittings are tested for quality and they are marked and coated with rust preventive oil before being bundled and dispatched.


ASTM B366 specification stands for nickel alloy pipe fittings including Inconel. Monel, Hastelloy and Nickel Alloy used for pressure vessels and chemical industry.
