    Abstract

    This specification covers the requirements for 33 grades of titanium and titanium alloy welded pipe intended for general corrosion resisting and elevated temperature service. Welded pipe shall be made from annealed flat-rolled products by a welding process. Welded pipe may be further reduced by cold working or hot working. Grades 1, 2, 2 H, 7, 7H, 11,13, 14, 16, 16H, 17, 26H, 33, and 37 shall be furnished as welded or annealed. Grades 3, 12, 15, and 34 shall be furnished as annealed. Grade 5, 23, 24, 25, 35 shall be furnished as annealed, or aged. Grade 9, 18, 38 shall be furnished as annealed. Grade 19, 20, 21 shall be furnished as solution treated, or solution treated and aged. The materials shall conform to the required chemical composition for nitrogen, carbon, hydrogen, iron, oxygen, aluminum, vanadium, tin, ruthenium, palladium, cobalt, molybdenum, chromium, nickel, niobium, zirconium, silicon, and titanium. They shall also conform to the required mechanical propetries such as tensile strength, yield strength, and elongation.

    Note 1H grade material is identical to the corresponding numeric grade (that is, Grade 2H = Grade 2) except for the higher guaranteed minimum UTS, and may always be certified as meeting the requirements of its corresponding numeric grade. Grades 2H, 7H, 16H, and 26H are intended primarily for pressure vessel use.

    1.2 Pipe 8 in. NPS (nominal pipe size) and larger is most frequently custom made for an order. In such cases, the purchaser carefully should consider the applicability of this specification. Since the pipe is custom made, the purchaser may choose a wall thickness other than those in Table 1 to meet specific operating conditions. The purchaser may also be better served to specify only the portions of this specification that are required to meet the operating conditions (for example, annealing, flattening test, chemistry, properties, etc.).

    TABLE 1 Dimensions of Pipe
    Note 1Schedule sizes conform to ANSI/ASME B 36.19M-1985 (for “S” sizes) or B 36.10 (for non-S sizes).
    Note 2The decimal thickness listed for the respective pipe sizes represent their nominal wall dimensions.
