ASTM A106 Gr.B Seamless Steel Pipes

Short Description:

ASTM A106/ASME SA106 is the standard specification for seamless carbon steel pipes for high temperature applications. It consists of three grades A, B and C, the commonly used grade is A106 grade B. It is not only used in pipeline systems such as oil and gas, water, and slurry transportation, but also in boilers, construction and structural applications.

Product Introduction

ASTM A106 Grade B pipe is chemically equivalent to ASTM A53 Grade B and API 5L Grade B in terms of chemical position and mechanical properties, generally using carbon steel, with a minimum yield strength of 240 MPa and a tensile strength of 415 MPa.

ASTM A106 Standard Specification for Seamless Steel Pipe has three grades, ASTM A106 Gr.A grade. B and C, the higher the material grade, the better the strength properties.
