GOST 17217-79 PDF

Full title and description

GOST 17217-79 — "Трубы из медно-никелевого сплава марки МНЖ5-1. Технические условия" (Tubes of copper‑nickel alloy MNZh5-1 — Specifications). The standard sets technical requirements, dimensional tolerances, chemical and mechanical property limits, test methods, marking, packing and storage rules for cold‑worked and pressed tubes made of the copper‑nickel alloy MNZh5‑1, primarily intended for shipbuilding and related heat‑exchange applications.

Abstract

GOST 17217-79 is a technical specification that defines manufacture, acceptance testing and quality assurance requirements for tubes made from the copper‑nickel alloy MNZh5‑1. It covers material designation, required chemical composition and mechanical properties, dimensional series and tolerances, non‑destructive and destructive testing procedures, packaging, marking and transportation rules relevant to maritime and industrial heat‑exchange uses.

Scope

The standard applies to cold‑deformed and pressed seamless tubes manufactured from the copper‑nickel alloy grade MNZh5‑1. It specifies allowable dimensions and tolerances, chemical and mechanical requirements, sampling and test methods (including nondestructive inspection), acceptance criteria, marking, packaging, transportation and storage intended primarily for shipbuilding and heat‑exchange equipment. It does not cover welded tube types or tubes of other alloys unless expressly referenced.

Key topics and requirements

• Chemical composition limits for alloy MNZh5‑1 and permitted variation during manufacture.
• Mechanical property requirements (tensile strength, elongation, hardness) for different product conditions and diameters.
• Dimensional ranges, wall‑thickness classes and tolerances for external diameter and wall thickness.
• Sampling and test procedures: destructive tests (tensile, flattening, dimensional checks) and nondestructive methods (ultrasonic, eddy‑current) with referenced calibration/setup rules.
• Acceptance criteria for surface quality, permissible defects and condition (hard/soft states); procedures for removal and retesting of defective material.
• Packing, marking and transportation rules specific to tube weight, bundling and crate types; storage recommendations for preserving corrosion resistance.
• Normative references and cross‑references to related GOSTs for test methods and packaging (for example, standards on ultrasonic testing, sampling, packing and marking).

Typical use and users

Typical users are tube manufacturers, quality and test laboratories, procurement and engineering departments in shipbuilding, designers and OEMs of heat exchangers, condensers and marine piping systems, and suppliers/distributors of copper‑nickel tubes. The standard is used to specify material for seawater systems, condensers, and other applications where corrosion resistance of the MNZh5‑1 alloy is required.
