Question

Accepted Answer

The basic difference between Pipe specification A106 Gr.A / Gr.B/ Gr.C is the carbon content and mechanical properties.

A106 Gr.A has the lowest carbon content and is suitable for low-temperature applications.
A106 Gr.B has a slightly higher carbon content and is commonly used for high-temperature applications.
A106 Gr.C has the highest carbon content and offers better mechanical properties.
Gr.B and Gr.C are interchangeable in terms of pressure and temperature ratings.
The choice of grade depends on the specific requirements of the piping system.

Accepted Answer

Gr.A CARBON PERCENTAGE 0.25%

Gr.B CARBON PERCENTAGE 0.30%

Gr.C CARBON PERCENTAGE 0.35%

Accepted Answer

In my opinion, A106 is only known for Seamless (Seamless carbon pipe) products available in three steel grades A,B,C.
