This specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures. Ibikoresho byo kuri fottings bigizwe nicyuma bishwe, imibarire, ibibari, amasahani, ibicuruzwa birenze cyangwa bisukuye cyangwa gusunika. Guhimbaza cyangwa gukora ibikorwa bishobora gukorwa mu nyundo, ukanda, utontoma, uhindagurika, kuzunguruka, kuzunguruka, kuzunguruka, gukomera, cyangwa ku bijyanye n'ibikorwa bibiri cyangwa byinshi muribi bikorwa. The forming procedure shall be so applied that it will not produce injurious imperfections in the fittings. Fittings, nyuma yo gukora ubushyuhe bwo hejuru, bizakonjesha ubushyuhe munsi yimiterere iboneye mu rwego rwo kwirinda ubukonje bwihuse, ariko nta rubanza rwihuse kuruta igipimo gikonje.
