GOST 10092-2006 PDF

Full title and description

GOST 10092-2006 — Cupro‑nickel tubes for heat‑exchange apparatus. Specifications. National/interstate standard that establishes requirements for cold‑worked (cold‑drawn/cold‑rolled) cupro‑nickel (melchior) seamless tubes intended primarily for heat‑exchange equipment and related products.

Abstract

This standard specifies the assortment (sizes and limits), chemical and mechanical requirements, inspection and testing methods, acceptance rules, marking, packing, transportation and storage for seamless cupro‑nickel tubes used in heat exchangers. It sets dimensional tolerances, allowable defects and non‑destructive and destructive test procedures (including hydrostatic/pneumatic leak tests and eddy‑current inspection) needed to ensure product fitness for service.

• Number of pages: 19 (text of the standard).

Scope

Applies to cold‑deformed seamless cupro‑nickel (melchior) tubes intended for the manufacture of heat‑exchange apparatus and other products. The standard covers tube dimensions (diameter, wall thickness, lengths), materials/grades, technical requirements, sampling and acceptance criteria, methods of inspection and testing, packaging, marking, transportation and storage rules.

Key topics and requirements

• Material grades and chemical composition for typical cupro‑nickel alloys used (melchior types such as MNZhMts10‑1‑1, MNZhMts30‑1‑1 and similar specifications).
• Permitted dimensional range and tolerances — outside diameters and wall thicknesses commonly covered (typical diameters about 10–50 mm, wall thicknesses ~0.8–4 mm; lengths up to typical mill lengths — e.g., up to 14 m — as specified by producers/agreement).
• Cold‑worked, seamless tube manufacturing methods and requirements for surface condition, straightness and end‑cut quality.
• Mechanical property requirements (tensile strength, yield/temporary resistance where applicable) and hardness measurement methods (Vickers where referenced).
• Chemical‑analysis requirements and test methods for copper, nickel, iron, zinc, manganese and other alloying elements.
• Non‑destructive inspection: mandatory/optional eddy‑current testing procedures, acceptance levels and defect classification.
• Leak and integrity tests: hydrostatic and pneumatic test methods and acceptance (pressure ranges and test duration as specified for detection of through‑wall defects; such tests are not to be construed as pressure‑rating proofs).
• Sampling, acceptance rules and criteria for lot release, including handling of nonconforming pipes.
• Packaging, marking, transport and storage instructions to preserve tube condition and traceability.

Typical use and users

Used by manufacturers and purchasers of heat‑exchanger tubing, boiler and condenser fabricators, HVAC and process engineering companies, tube mills and metal distributors, inspection and test laboratories, and procurement/specification engineers who require standardized cupro‑nickel tubing for corrosion‑resistant heat‑exchange service in marine, chemical, power and industrial applications.

Related standards

References and related documents typically cited or used alongside GOST 10092‑2006 include the predecessor GOST 10092‑75, other GOST technical references for chemical and test methods (for example standards covering nickel and copper‑nickel alloys, hardness testing, hydraulic pressure testing, measuring instruments and packing), and international counterparts for copper alloy tubing (for example EN/ISO norms covering copper and copper‑alloy tubes such as EN 12449 and other regional/specification standards). Specific normative references appear in the standard text (test methods, measuring tools and metallurgical analysis standards).

FAQ

Q: What is this standard?

A: GOST 10092‑2006 is an interstate (GOST) standard that specifies technical requirements and test/acceptance rules for cold‑deformed cupro‑nickel (melchior) seamless tubes intended for heat‑exchange apparatus.

Q: What does it cover?

A: It covers tube dimensions and tolerances, allowable materials/grades and chemical composition, mechanical and physical requirements, inspection and testing methods (including eddy‑current and hydrostatic/pneumatic tests), sampling and acceptance criteria, marking, packaging, transportation and storage.

Q: Who typically uses it?

A: Tube manufacturers and mills, heat‑exchanger and condenser fabricators, materials engineers, procurement/specification teams, testing laboratories and distributors that supply or require cupro‑nickel tubing for corrosion‑resistant heat transfer applications.

Q: Is it current or superseded?

A: GOST 10092‑2006 replaced the earlier GOST 10092‑75. It was accepted by protocol on 24 June 2006, adopted by Order No. 500‑St dated 27 December 2006 and came into force as a national standard in the Russian Federation on 1 January 2008. As with any standards, users should confirm current status with the relevant national standards body (Rosstandart or the interstate standards commission) to check for later amendments or formal withdrawal.

Q: Is it part of a series?

A: It is part of the body of standards governing non‑ferrous metal pipes and related test methods; the standard cross‑references multiple GOST normative documents on alloy composition, test methods and measuring equipment. It is not a multi‑part numbered series itself but sits within the GOST system for tube and pipe specification and is associated with other GOSTs for copper/nickel alloys and testing procedures.

Q: What are the key keywords?

A: Cupro‑nickel, melchior, seamless tube, heat exchanger, cold‑worked, eddy‑current, hydrostatic test, GOST 10092‑2006, non‑ferrous pipes.
