Full title and description

Standard Specification for Common Requirements for Steel Flanges, Forged Fittings, Valves, and Parts for Piping Applications — Russian-language product listing for ASTM A961/A961M-19 (original standard text published in English). This document groups the common requirements that apply across multiple individual product specifications for steel piping components.

Abstract

This specification establishes common requirements (materials, melting practices, heat treatment, inspection, marking, and packaging) that apply to steel flanges, forged fittings, valves, and related parts intended for piping applications. It is intended to be used in conjunction with the applicable individual product specifications (for example A105/A105M, A181/A181M, A182/A182M), with the individual product specification taking precedence in case of conflict.

Scope

The standard covers a set of common requirements applicable to steel flanges, forged fittings, valves, and parts for piping applications called out by individual product specifications. It addresses material source and melting practice (primary and secondary melting/refining), heat treatment and post‑fabrication treatments (full anneal, solution anneal, normalizing, tempering, post‑weld heat treatment, stress relieving), inspection and testing requirements, marking, packaging, and the use of inch‑pound and SI (M) units. Where requirements conflict, the individual product specification governs.

Key topics and requirements

• Applicability of common requirements across multiple product specifications (flanges, forged fittings, valves, parts).
• Melting and remelting practices: primary melting requirements, optional secondary remelting (electroslag, vacuum remelting), and heat definition criteria.
• Heat treatment procedures and requirements (annealing, normalizing, tempering, solution treatment, PWHT, stress relieving).
• Specified mechanical and chemical testing where required by the individual product specification (tensile, hardness, chemical analysis, impact as applicable).
• Non‑destructive examination and inspection practices referenced (for example magnetic particle examination where applicable).
• Marking, packaging, and purchaser‑supplier agreement provisions for any additional or special requirements.
• Dual‑unit handling: inch‑pound and SI (M) units treated separately; the inch‑pound system applies unless the M designation is specified in the order.

Typical use and users

Used by manufacturers of flanges, forged fittings, valves and related piping components, quality and inspection engineers, material purchasers, pipeline and plant owners (oil & gas, petrochemical, power generation, utilities), and certification bodies to ensure consistent common requirements across product specifications and to provide ordering, inspection, and traceability guidance.
