Introduction

The GB/T 31941 Q205HD; Q230HD; Q250HD; Q275HD; Q345HD1 standard specifies the requirements for welded carbon steel and alloy steel pipes used in non-nuclear ety class applications within nuclear power plants. These pipes are designed to withstand high-pressure and high-temperature conditions, ensuring the e and efficient operation of nuclear power plants.

Material and Specification

The material used in the production of GB/T 31941 Q205HD; Q230HD; Q250HD; Q275HD; Q345HD1 welded steel tubes is carbon steel and alloy steel. The specification outlines the following key features:

  • Welded construction: The pipes are manufactured using a welding process, ensuring a strong and reliable joint.
  • Non-nuclear ety class: These pipes are specifically designed for applications that do not involve direct contact with nuclear materials or critical ety systems.
  • High-pressure and high-temperature resistance: The pipes are capable of withstanding extreme conditions commonly encountered in nuclear power plants.

Chemical Composition

The chemical composition of the GB/T 31941 Q205HD; Q230HD; Q250HD; Q275HD; Q345HD1 welded steel tubes is as follows:

Steel Grade Chemical Composition (%)
Q205HD C: ≤0.12, Si: ≤0.30, Mn: ≤0.50, P: ≤0.035, S: ≤0.035
Q230HD C: ≤0.18, Si: ≤0.30, Mn: ≤0.50, P: ≤0.035, S: ≤0.035
Q250HD C: ≤0.22, Si: ≤0.30, Mn: ≤0.50, P: ≤0.035, S: ≤0.035
Q275HD C: ≤0.28, Si: ≤0.30, Mn: ≤0.50, P: ≤0.035, S: ≤0.035
Q345HD1 C: ≤0.20, Si: ≤0.55, Mn: ≤1.00, P: ≤0.035, S: ≤0.035

Mechanical Properties

The mechanical properties of the GB/T 31941 Q205HD; Q230HD; Q250HD; Q275HD; Q345HD1 welded steel tubes are as follows:

Steel Grade Tensile Strength (MPa) Yield Strength (MPa) Elongation (%)
Q205HD ≥315 ≥205 ≥33
Q230HD ≥375 ≥230 ≥26
Q250HD ≥390 ≥250 ≥24
Q275HD ≥410 ≥275 ≥22
Q345HD1 ≥490 ≥345 ≥21

Steel Grade and Application

The GB/T 31941 Q205HD; Q230HD; Q250HD; Q275HD; Q345HD1 welded steel tubes are available in different steel grades, each suitable for specific applications within nuclear power plants. The steel grades and their corresponding applications are as follows:

  • Q205HD: Suitable for general piping systems within nuclear power plants.
  • Q230HD: Ideal for high-temperature steam pipelines and heat exchangers.
  • Q250HD: Designed for high-pressure coolant systems and reactor internals.
  • Q275HD: Used in primary coolant systems and pressure vessels.
  • Q345HD1: Recommended for main coolant systems and steam generators.

Possible Alternative Grades

While the GB/T 31941 Q205HD; Q230HD; Q250HD; Q275HD; Q345HD1 welded steel tubes are specifically designed for nuclear power plant applications, there may be alternative grades available depending on specific project requirements. It is essential to consult with experts and adhere to relevant standards and regulations when considering alternative grades.
