Standard Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service
ASTM A234/A234M – 15
Scope
This specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction covered by the latest revision of ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures. The M in the designation stands for metric.
Materials
The starting material for fittings shall be fully killed steel, consisting of forgings, bars, plates, sheet, and seamless or fusion-welded tubular products with filler metal added and shall conform to the chemical requirements. Unless otherwise specified for carbon steel plates and sheet, the steel may be made to either coarse grain or fine grain practice. Grade WP9 shall be made to fine grain practice.
Chemical Requirements
NOTE 1: All requirements are maximum unless otherwise indicated.
NOTE 2: Where an ellipsis (...) appears in this table, there is no requirement and analysis for the element need not be determined or reported.

Protection

Astm A335 standard specication for seamless ferritic alloy-steel pipe for high-temperature service

ASTM A335 standard is issued under the fixed designation A 335/A 335M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

Astm A335 standard specication for seamless ferritic alloy-steel pipe

This specification covers nominal (average) wall seamless alloy-steel pipe intended for high-temperature service (Mote 1). Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Selection will depend upon design, service conditions, mechanical properties, and high-temperature characteristics.
