《GB/T 44327-2024锆及锆合金焊管》由TC243（全国有色金属标准化技术委员会）归口，TC243SC3（全国有色金属标准化技术委员会稀有金属分会）执行，主管部门为中国有色金属工业协会。


Introduction

1. Standard Overview

GB/T 44327-2024 "Zirconium and Zirconium Alloy Welded Pipes" national standard specifies the classification, technical requirements, test methods, inspection rules, etc. of zirconium and zirconium alloy welded pipes, and is applicable to general industrial zirconium and zirconium alloy welded pipes.

2. Classification and application

Category Purpose Grade State
Class I Welded pipe for heat exchanger Zr﹘1, Zr﹘3, Zr﹘5 Annealed state (M)
Class II Welded pipe for pipeline Zr﹘1, Zr﹘3, Zr﹘5 Welded state (H), annealed state (M)

3. Interpretation of technical requirements

Chemical composition and tensile properties

The chemical composition of zirconium and zirconium alloys must comply with the requirements of GB/T 26314, and the room temperature tensile properties must be tested according to GB/T 228.1. 200~305 ≥20 Zr﹘3 ≥380 ≥205 Zr﹘4 ≥500 ≥200 ≥500 Zr﹘5 ≥500 ≥200 ≥500 ≥16 Zr﹘5 ≥550 ≥380 ≥16

4. Implementation Suggestions

To ensure the quality of zirconium and zirconium alloy welded pipes, it is recommended that:

  • Chemical composition and mechanical properties should be tested in strict accordance with the standards.
  • Select appropriate non-destructive testing methods (ultrasonic, eddy current, etc.).
  • Focus on welding process optimization to ensure joint quality.
  • When used in high temperature or corrosive environments, high alloy grades are preferred.
