ASTM A106 Gr.B Pipe / Seamless Steel Pipe EN 1.0405 Steel Pipe for
Structure
ASTM A106 pipe is the carbon seamless steel pipe that widely used
for different industries. For oil and gas pipelines, water
transmissions, mineral slurry, boiler and high pressure services,
construction and structural.
A106 pipe has three grades: Grade A and Grade B and C, where in
most circumstances used for Grade B.

ASTM A106 standard specifications
ASTM A106 is the standard specification for seamless carbon steel
pipe applied for high temperature services.
Dimensions Schedule Range
The standard covers pipe sizes in NPS (National Standard Straight)
from 10.3mm DN6 – 1219mm DN1200 (1/8 inch to 48 inch), complied
with ASME B 36.10M. But other sizes out of this B36.10 also could
apply the A106 standard.
ASTM A106 Pipe Specifications
Raw materials
ASTM A106 standard raw material is carbon steel, it shall be
applicable for bending, flanging or similar forming processes.

Scope
ASTM A106 Seamless Pressure Pipe (also known as ASME SA106 pipe)
covers seamless carbon steel nominal wall pipe for high-temperature
service. Suitable for bending, flanging and similar forming
operations.
NPS 1-1/2″ and under may be either hot finished or cold drawn. NPS
2″ and larger shall be hot finished unless otherwise specified.
Process
Killed steel, with primary melting process being open-hearth,
basic-oxygen, or electric-furnace, possibly combined with separate
degassing or refining.
Steel cast in ingots or strand cast is permissible.
Hot-finished pipe need not be heat treated.
Cold-drawn pipe shall be heat treated after the final cold draw
pass.

Grade B Seamless Pipe
ASTM A106 standard specifications for the seamless steel pipe have
three grades, that is ASTM A106 Gr. A, Grade. B and C, with the
higher grade material, the strength performance is better.
Test Methods
The test methods for the ASTM A106 A, B, C are the flattening
tests, hydrostatic test, nondestructive electric test, Ultrasonic
test, eddy current test, flux leakage test, these test procedures
shall be notified or discussed with client to confirm what kind of
test will be applied.
