    ASTM A106 GR.B A53 GR.B Black Carbon Seamless Steel Pipe
    According to the material,the pipes can divide into Carbon Steel Seamless Pipes and Alloy Steel Seamless Pipes.For carbon steel seamless pipes,the mechanical property is much lower than alloy steel materials.Especially the tensile strength and yield strength.
    So carbon steel pipes mainly used in transport petroleum,oil,gas and construction material.But alloy steel pipes can widely used in high pressure boiler system,heat exchanger,mechanical property.
