Description

ASME SA334 GR.6 Carbon Steel,Low Temperature,Seamless Tube For Condenser Tube Bundle, Boiler, Heat Exchanger, Condenser, Superheater, HRSG

ASME SA334 Gr.6 seamless pipe is a type of carbon steel pipe used in cryogenic applications. Its main difference from other grades of the same standard is that it is nickel-free, resulting in lower costs, and it is suitable for temperatures above -45°C.

The material has excellent weldability and has undergone hydrostatic or non-destructive testing to ensure safety and reliability in the manufacture of heat exchange equipment or pressure pipelines.

It is used in almost all well-known LNG, polar oil and gas, and large-scale chemical projects.

Chemical Composition
Element Composition (%) Note
Carbon (C) ≤ 0.30
Manganese (Mn) 0.29 - 1.06
Phosphorus (P) ≤ 0.025
Sulfur (S) ≤ 0.025
Silicon (Si) 0.10 - 0.35
Copper (Cu) ≥ 0.40 (min) When specified as Copper-bearing steel
Aluminum (Al) ≥ 0.02 (min) For grain refinement, may be used in place of silicon killing

Mechanical & Technological Properties
Property Requirement / Value Note / Condition
Tensile Strength ≥ 415 MPa (≥ 60,000 psi)
Yield Strength ≥ 240 MPa (≥ 35,000 psi)
Elongation (in 2 in. or 50mm) ≥ 35 % (min) Minimum for wall thickness ≥ 0.07 in. (1.8 mm)
Heat Treatment Normalized Mandatory for achieving low-temperature properties.
Impact Test Charpy V-Notch (CVN) Required
Test Temperature -50°F (-45°C)
Minimum Impact Energy Average of 3 specimens: ≥ 13.7 J (10 ft·lbf)
Single specimen: ≥ 11.4 J (8.4 ft·lbf)
Hardness As per applicable code limits Typically specified in the purchase agreement or governing design code.
Manufacturing Process Primarily Seamless Welded tube is permitted by the specification but less common for this grade.

Application:

  • Liquefied Natural Gas (LNG) Systems: LNG receiving terminals, liquefaction units, storage tanks, and external pipelines.
  • Air Separation Equipment: Pipeline transportation of liquid nitrogen, liquid oxygen, and liquid argon.
  • Cryogenic Refrigeration Engineering: Such as ethylene and propylene refrigeration systems.
  • Outdoor Pipelines in Cold Regions
