Seamless carbon steel pipe for high temperature service

Date:2021-06-15View:70Tags:Seamless carbon steel pipe for high temperature service

Basically there are three types of High Temperature Steel Pipe:

High Temperature Carbon Steel pipe

High Temperature Alloy Steel pipe

High Temperature Stainless Steel tube

High Temperature Carbon Steel tube

 

High Temperature service tube are typically knows as heat exchanger tube, which operates at 400 degree Celsius to 1100 degree Celsius.

Steel GradeThere are various grades of steel to manufacture steel pipe for high temperatures service, such as ASTM A106,A179, A192, A210

 

Parameters of Steel Pipe for High heat Service

1. Mechanical Properties

Standard Grade Tensile Strength (MPa) Yield Strength (MPa)
ASTM A106 A ≥ 330 ≥ 205
B ≥ 415 ≥ 240
C ≥ 485 ≥ 275

2. Chemical Composition of Seamless Carbon Steel Pipe

Standard Grade Chemical Composition
C Si Mn P S Cr Mo Cu Ni V
ASTM A106 A ≤ 0.25 ≥ 0.10 0.27-0.93 ≤ 0.035 ≤ 0.035 ≤ 0.40 ≤ 0.15 ≤ 0.40 ≤ 0.40 ≤ 0.08
B ≤ 0.30 ≥ 0.10 0.29-1.06 ≤ 0.035 ≤ 0.035 ≤ 0.40 ≤ 0.15 ≤ 0.40 ≤ 0.40 ≤ 0.08
C ≤ 0.35 ≥ 0.10 0.29-1.06 ≤ 0.35 ≤ 0.35 ≤ 0.40 ≤ 0.15 ≤ 0.40 ≤ 0.40 ≤ 0.08

ASTM A179 / A179M - 90a Standard Specification for Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser Tubes

ASTM A192 / A192M Standard Specification for Seamless Carbon Steel Boiler Tubes for High-Pressure Service

ASTM A210/ASME SA210 Standard Specification for Seamless Medium-Carbon Steel Boiler and Superheater Tubes.

High Temperature Alloy Steel tube

ASTM A213, A209 specification covers Alloy Steel Seamless tube for high temperature service. These tube are suitable for bending and similar forming operations, and for fusion welding at high temperatures.

 

Application:

heating-pipelines, containers, coal-saving devices superheaters and reheaters of high temperature and high press boiler(P>=9.8MPa, T>450oC)
