Introduction

Interpretation of the Standard for Aluminum Alloy Extruded Pipes for Non-nuclear Grade Nuclear Power Cooling

1. Background of Standard Formulation and Analysis of Technology Evolution

GB/T 37579-2019 "Aluminum Alloy Extruded Pipes for Non-nuclear Grade Nuclear Power Cooling" is a standard proposed by the China Nonferrous Metals Industry Association and managed by the National Technical Committee for Nonferrous Metals Standardization. The formulation of this standard fills the gap in the domestic standard for special aluminum materials in the nuclear energy field, which is of great significance to improving the industry's technical level and product quality.

2. Comparison of standard framework and product classification

Category	Requirement	Example brand
Product classification	Auxiliary cooling water system and closed cooling water system in the secondary and tertiary system pipelines of the conventional island of a pressurized water reactor nuclear power plant.	4032, 6061, 6101A
Brand and state	T6 state, suitable for high temperature and high corrosion environment.	6A02, 6063A

3. Mechanical properties and salt spray corrosion requirements

Mechanical properties:

Room temperature tensile: tensile strength ≥200 MPa, elongation after break ≥6%.
High temperature tensile (185℃): tensile strength ≥300 MPa.

Salt spray corrosion performance:

Neutral salt spray test for 72 hours, no pitting, cracks or bubbles.
Applicable to nuclear power systems in high humidity and corrosive environments.

4. Implementation suggestions

Manufacturer:

Material procurement and production should be carried out strictly in accordance with standards.
Establish a sound quality control system to ensure that the chemical composition and mechanical properties meet the requirements.

Testing agency:

Carry out hydraulic test and expansion test according to GB/T 241 and GB/T 242.
Periodically check the salt spray corrosion performance to ensure long-term reliability.

Purchaser:

Specify the special requirements in the order (such as air pressure performance).
Consult with the supplier to determine the batch inspection plan to ensure the quality of the delivered products.
