Overview

ASTM B862-23: Standard Specification for Titanium and Titanium Alloy Welded Pipe provides comprehensive requirements for the manufacture, chemical composition, mechanical properties, and testing of welded pipes made from 33 grades of titanium and titanium alloys. Developed by ASTM International, this standard is designed for pipes intended for general corrosion resistance and elevated temperature service applications. ASTM B862-23 ensures that titanium welded pipes meet stringent quality and performance criteria for use in a variety of demanding environments.

Key Topics

Key aspects of ASTM B862-23 include:

• Product Scope: Covers 33 grades of titanium and titanium alloy welded pipe, including unalloyed grades and those with specific alloying elements such as aluminum, vanadium, palladium, ruthenium, nickel, chromium, and others.
• Manufacturing Methods: Specifies welded pipe production from annealed flat-rolled products, which may be further processed by hot or cold working. Requirements for welding, annealing, and aging are detailed based on the grade.
• Chemical Composition: Defines strict limits for elements including nitrogen, carbon, hydrogen, iron, oxygen, aluminum, vanadium, and others to ensure material purity and suitability.
• Mechanical Properties: Sets minimum requirements for tensile strength, yield strength, and elongation for each pipe grade.
• Testing and Inspection: Mandates mechanical testing, chemical analyses, hydrostatic testing, dimensional checks, and optional supplementary requirements such as liquid penetrant testing.
• Dimensions and Tolerances: Provides nominal pipe sizes, schedules, wall thicknesses, and allowable dimensional tolerances aligned with ANSI/ASME standards.
• Certification and Marking: Specifies the need for traceable marking and comprehensive certification for each pipe segment.

Applications

Titanium and titanium alloy welded pipes manufactured to ASTM B862-23 are widely used in industries that demand high corrosion resistance and performance under elevated temperatures, including:

• Chemical Processing: Piping systems handling corrosive chemicals, acids, and chlorides, where titanium’s inertness extends service life.
• Oil & Gas: Offshore and subsea piping, heat exchangers, and flowlines where resistance to seawater corrosion is crucial.
• Power Generation: Condenser and heat recovery piping in thermal and nuclear power plants.
• Aerospace and Defense: Lightweight, high-strength piping in fuel and hydraulic systems.
• Pharmaceutical and Medical: Process lines where purity and biocompatibility of titanium alloys support stringent regulatory requirements.
• Desalination & Marine: Piping exposed to saltwater and corrosive marine environments.

ASTM B862-23 welded titanium pipes are selected where reliability, longevity, and minimal maintenance are critical, especially in aggressive media or high-stress applications.

Practical Value

By adhering to ASTM B862-23, manufacturers, engineers, and end users can ensure that titanium and titanium alloy welded pipes are suitably engineered for demanding service conditions. The standard enables selection of the correct grade and condition for specific processes, ensures material traceability, and provides confidence in meeting international compliance requirements for safety and performance.

NOTE 1—H 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.).

A
At minimum, the analysis of samples from the top and bottom of the ingot shall be completed and reported for all elements listed for the respective grade in this table.
B
Final product hydrogen shall be reported. Ingot hydrogen need not be reported. Lower hydrogen may be obtained by negotiation with the manufacturer.
C
Single values are maximum. The percentage of titanium is determined by difference.
D
Other elements need not be reported unless the concentration level is greater than 0.1 % each, or 0.4 % total. Other elements may not be added intentionally. Other elements may be present in titanium or titanium
alloys in small quantities and are inherent to the manufacturing process. In titanium these elements typically include aluminum, vanadium, tin, chromium, molybdenum, niobium, zirconium, hafnium, bismuth, ruthenium,
palladium, yttrium, copper, silicon, cobalt, tantalum, nickel, boron, manganese, and tungsten.

requirements of this specification. Filler metal, if used, shall be produced to the latest revision of Specification
AWS A5.16 ⁄A5.16M-2013 employing the ER Ti-X grade listed in Table 5, unless specified otherwise on the purchase order.
5.1.1 Welded pipe may be further reduced by cold working or hot working. Cold reduced pipe shall be annealed after cold working
at a temperature of not less than 1000°F.1000 °F. Hot worked pipe finished above 1400°F (760°C)1400 °F (760 °C) need not be
further heat treated.
5.2 Pipe shall be furnished as follows unless otherwise specified:
5.2.1 Grades 1, 2, 2H, 7, 7H, 11, 13, 14, 16, 16H, 17, 26H, 33, 37, and 39 shall be furnished as welded or annealed.
