- CS SEAMLESS RECTANGULAR PIPE ASTM A 106 GR. B / CARBON STEEL SEAMLESS RECTANGULAR PIPE ASTM A 106 GR. 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.
Raw materials
ASTM A106 standard raw material is carbon
steel, it shall be applicable for bending, flanging or similar forming
processes.
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.
Chemical composition in %
Carbon (C) Max For Grade A 0.25, For Grade B 0.30, Grade C 0.35
Manganese (Mn): 0.27-0.93, 0.29-1.06
Sulfur (S) Max: ≤ 0.035
Phosphorus (P) : ≤ 0.035

Please note:
For each reduction of 0.01% for maximum carbon element, an increase of 0.06%
manganese above the specified value shall be permitted, and up to maximum of
1.35%.
Elements Cr, Cu, Mo, Ni, V combined shall not exceed 1%.
