(Specification)Standard Specification for Titanium-Stabilized Carbon Steel Forgings for Glass-Lined Piping and Pressure Vessel Service
Standard Specification for Titanium-Stabilized Carbon Steel Forgings for Glass-Lined Piping and Pressure Vessel Service
ABSTRACT
This specification covers non-standard titanium-stabilized carbon steel forgings, as-forged fittings, and valve components and parts for glass-lined piping and pressure vessel service. Materials shall be manufactured by forging in the manner of hammering, pressing, rolling, extruding, or upsetting. Mechanical properties are certified on the basis of test material subjected to heat treatments to simulate glass-coating operations. Specimens shall conform to chemical composition and tensile requirements, such as tensile strength, yield strength, elongation, and reduction of area. A single retest may be performed to establish product acceptability when one or more representative test specimen does not conform to specifications. Repair welding shall be required only upon the approval of the purchaser.
SCOPE
1.1 This specification covers nonstandard as-forged fittings, valve components, and parts for glass-lined piping and pressure vessel service. Mechanical properties are certified on the basis of test material subjected to heat treatments to simulate glass-coating operations.
1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
